[0054] In optical communication technology, to establish information transmission between information processing devices, it is necessary to load the information onto light and use the propagation of light to achieve information transmission. Here, the light loaded with information is an optical signal. When transmitting optical signals within information transmission equipment, they can reduce optical power loss, thereby enabling high-speed, long-distance, and low-cost information transmission. The signals that information processing equipment can recognize and process are electrical signals. Information processing equipment typically includes optical network units (ONUs), gateways, routers, switches, mobile phones, computers, servers, tablets, televisions, etc., and information transmission equipment typically includes optical fibers and optical waveguides.

[0055] Optical modules can convert optical signals into electrical signals between information processing devices and information transmission devices. For example, at least one of the optical signal input or output ends of an optical module is connected to an optical fiber, and at least one of the electrical signal input or output ends of the optical module is connected to an optical network terminal. A first optical signal from the optical fiber is transmitted to the optical module, which converts the first optical signal into a first electrical signal and transmits the first electrical signal to the optical network terminal. A second electrical signal from the optical network terminal is transmitted to the optical module, which converts the second electrical signal into a second optical signal and transmits the second optical signal to the optical fiber. Because multiple information processing devices can transmit information via electrical signals, at least one of the multiple information processing devices needs to be directly connected to the optical module, rather than all of them. Here, the information processing device directly connected to the optical module is referred to as the optical module's host computer. Furthermore, the optical signal input or output end of the optical module can be referred to as an optical port, and the electrical signal input or output end of the optical module can be referred to as an electrical port.

[0056] FIG1 is a partial structural diagram of an optical communication system according to some embodiments. As shown in FIG1 , the optical communication system mainly includes a remote information processing device 1000 , a local information processing device 2000 , a host computer 100 , an optical module 200 , an optical fiber 101 , and a network cable 103 .

[0057] One end of optical fiber 101 extends toward remote information processing device 1000, and the other end of optical fiber 101 is connected to optical module 200 through the optical port of optical module 200. Optical signals can be totally reflected in optical fiber 101, and the propagation of the optical signal in the direction of total reflection can almost maintain the original optical power. The optical signal undergoes multiple total reflections in optical fiber 101 to transmit the optical signal from remote information processing device 1000 to optical module 200, and vice versa, thereby achieving long-distance, low-power information transmission.

[0058] The optical communication system may include one or more optical fibers 101, and the optical fibers 101 may be detachably connected or fixedly connected to the optical module 200. The host computer 100 is configured to provide data signals to the optical module 200, receive data signals from the optical module 200, or monitor or control the operating status of the optical module 200.

[0059] The host computer 100 includes a substantially rectangular housing and an optical module interface 102 disposed on the housing. The optical module interface 102 is configured to connect to the optical module 200 to establish a unidirectional or bidirectional electrical signal connection between the host computer 100 and the optical module 200.

[0060] The host computer 100 also includes an external electrical interface that can access an electrical signal network. For example, the external electrical interface includes a Universal Serial Bus (USB) interface or a network cable interface 104. The network cable interface 104 is configured to access a network cable 103 so that the host computer 100 establishes a unidirectional or bidirectional electrical signal connection with the network cable 103. One end of the network cable 103 is connected to the local information processing device 2000, and the other end of the network cable 103 is connected to the host computer 100, so that an electrical signal connection is established between the local information processing device 2000 and the host computer 100 via the network cable 103. For example, a third electrical signal emitted by the local information processing device 2000 is transmitted to the host computer 100 via the network cable 103. The host computer 100 generates a second electrical signal based on the third electrical signal. The second electrical signal from the host computer 100 is transmitted to the optical module 200. The optical module 200 converts the second electrical signal into a second optical signal and transmits the second optical signal to the optical fiber 101. The second optical signal is transmitted to the remote server 1000 via the optical fiber 101. For example, a first optical signal from the remote information processing device 1000 is transmitted through the optical fiber 101. The first optical signal from the optical fiber 101 is transmitted to the optical module 200. The optical module 200 converts the first optical signal into a first electrical signal. The optical module 200 transmits the first electrical signal to the host computer 100. The host computer 100 generates a fourth electrical signal based on the first electrical signal and transmits the fourth electrical signal to the local information processing device 2000. It should be noted that optical modules are tools for converting optical signals into electrical signals. During this conversion process, the information does not change, but the encoding and decoding methods of the information can change.

[0061] In addition to the optical network terminal, the host computer 100 also includes an optical line terminal (OLT), an optical network device (ONT), or a data center server.

[0062] Figure 2 is a partial structural diagram of a host computer according to some embodiments. To clearly illustrate the connection between the optical module 200 and the host computer 100, Figure 2 only shows the structure of the host computer 100 related to the optical module 200. As shown in Figure 2, the host computer 100 also includes a PCB circuit board 105 disposed within the housing, a cage 106 disposed on the surface of the PCB circuit board 105, a heat sink 107 disposed on the cage 106, and an electrical connector disposed within the cage 106. The electrical connector is configured to connect to the electrical port of the optical module 200; the heat sink 107 has raised structures such as fins to increase the heat dissipation area.

[0063] The optical module 200 is inserted into the cage 106 of the host computer 100. The cage 106 secures the optical module 200. Heat generated by the optical module 200 is transferred to the cage 106 and then dissipated through the heat sink 107. After the optical module 200 is inserted into the cage 106, the electrical port of the optical module 200 connects to the electrical connector inside the cage 106, thereby establishing a bidirectional electrical signal connection between the optical module 200 and the host computer 100. Furthermore, the optical port of the optical module 200 connects to the optical fiber 101, thereby establishing a bidirectional optical signal connection between the optical module 200 and the optical fiber 101.

[0064] Figure 3 is a structural diagram of an optical module according to some embodiments, and Figure 4 is an exploded view of an optical module according to some embodiments. As shown in Figures 3 and 4, the optical module 200 includes a housing, a circuit board 300 disposed within the housing, and an optical transceiver component 900.

[0065] The housing includes an upper housing 201 and a lower housing 202 . The upper housing 201 covers the lower housing 202 to form the housing having two openings 204 and 205 . The outer contour of the housing is generally a square.

[0066] In some embodiments, the lower shell 202 includes a base plate 2021 and two lower side plates 2022 located on both sides of the base plate 2021 and arranged perpendicular to the base plate 2021; the upper shell 201 includes a cover plate 2011, and the cover plate 2011 covers the two lower side plates 2022 of the lower shell 202 to form the above-mentioned shell.

[0067] In some embodiments, the lower shell 202 includes a base plate 2021 and two lower side plates 2022 located on both sides of the base plate 2021 and arranged perpendicularly to the base plate 2021; the upper shell 201 includes a cover plate 2011 and two upper side plates located on both sides of the cover plate 2011 and arranged perpendicularly to the cover plate 2011. The two upper side plates are combined with the two lower side plates 2022 to achieve the upper shell 201 covering the lower shell 202.

[0068] The direction of the line connecting the two openings 204 and 205 can be consistent with the length of the optical module 200, or it can be inconsistent with the length of the optical module 200. For example, opening 204 is located at the end of the optical module 200 (the right end in Figure 3), and opening 205 is also located at the end of the optical module 200 (the left end in Figure 3). Alternatively, opening 204 is located at the end of the optical module 200, while opening 205 is located on the side of the optical module 200. Opening 204 is an electrical port, from which the gold finger of the circuit board 300 extends and is inserted into the electrical connector of the host computer 100; opening 205 is an optical port, configured to receive an external optical fiber 101, so that the optical fiber 101 can connect to the optical transceiver component 900 in the optical module 200.

[0069] The combined assembly of the upper housing 201 and the lower housing 202 facilitates installation of the circuit board 300 and the optical transceiver 900 within the housing, which provides encapsulation and protection for these components. Furthermore, during assembly of the circuit board 300 and the optical transceiver 900, the positioning components, heat dissipation components, and electromagnetic shielding components of these components are easily positioned, facilitating automated production.

[0070] In some embodiments, the upper shell 201 and the lower shell 202 are made of metal materials, which facilitates electromagnetic shielding and heat dissipation.

[0071] In some embodiments, the optical module 200 further includes an unlocking component 600 located outside its housing. The unlocking component 600 is configured to achieve a fixed connection between the optical module 200 and the host computer, or to release the fixed connection between the optical module 200 and the host computer.

[0072] For example, the unlocking component 600 is located on the outside of the two lower side panels 2022 of the lower housing 202 and includes a snap-fit ​​component that mates with the cage 106 of the host computer 100. When the optical module 200 is inserted into the cage 106, the snap-fit ​​component of the unlocking component 600 secures the optical module 200 in the cage 106. When the unlocking component 600 is pulled, the snap-fit ​​component of the unlocking component 600 moves accordingly, thereby changing the connection between the snap-fit ​​component and the host computer, thereby releasing the optical module 200 from the cage 106 and allowing the optical module 200 to be removed from the cage 106.

[0073] The circuit board 300 includes circuit traces, electronic components, and chips. The electronic components and chips are connected according to the circuit design through the circuit traces to achieve functions such as power supply, electrical signal transmission, and grounding. Electronic components may include, for example, capacitors, resistors, transistors, and metal-oxide-semiconductor field-effect transistors (MOSFETs). Chips may include, for example, microcontroller units (MCUs), laser driver chips, transimpedance amplifiers (TIAs), limiting amplifiers, clock and data recovery chips (CDRs), power management chips, and digital signal processing (DSP) chips.

[0074] The circuit board 300 is generally a rigid circuit board. Due to its relatively hard material, the rigid circuit board can also realize the load-bearing function. For example, the rigid circuit board can stably carry the above-mentioned electronic components and chips; the rigid circuit board can also be inserted into the electrical connector in the cage 106 of the host computer 100.

[0075] The circuit board 300 also includes a gold finger formed on the surface of its end, and the gold finger is composed of a plurality of independent pins. The circuit board 300 is inserted into the cage 106, and the gold finger is connected to the electrical connector in the cage 106. The gold finger can be set only on the surface of one side of the circuit board 300 (for example, the upper surface shown in Figure 4), or it can be set on the upper and lower surfaces of the circuit board 300 to provide a larger number of pins, thereby adapting to occasions where a large number of pins are required. The gold finger is configured to establish an electrical connection with the host computer to achieve power supply, grounding, two-wire synchronous serial (Inter-Integrated Circuit, I2C) signal transmission, data signal transmission, etc. Of course, flexible circuit boards are also used in some optical modules. Flexible circuit boards are generally used in conjunction with rigid circuit boards to supplement rigid circuit boards.

[0076] In some embodiments, the optical transceiver component 900 includes only a first optical transceiver component, a second optical transceiver component or a third optical transceiver component, and the optical transceiver component 900 has both transmitting and receiving functions to realize at least one group of light transmission and at least one group of light reception.

[0077] In some other embodiments, the optical transceiver component 900 includes two first optical transceiver components, two second optical transceiver components or two third optical transceiver components that are staggered. The optical transceiver component 900 has both transmitting and receiving functions to realize two groups of light transmission and two groups of light reception.

[0078] In some other embodiments, the optical transceiver component 900 includes a first optical transceiver component and a second optical transceiver component that are staggered, or includes a first optical transceiver component and a third optical transceiver component that are staggered, or includes a second optical transceiver component and a third optical transceiver component that are staggered, and the optical transceiver component 900 has both transmitting and receiving functions to realize two groups of light transmission and two groups of light reception.

[0079] FIG5 is a cross-sectional view of the optical transceiver component and the circuit board provided in an embodiment of the present disclosure. FIG6 is an exploded view of the optical transceiver component and the circuit board provided in an embodiment of the present disclosure. As shown in FIG5 and FIG6 , an optical matching chip 302 and an optical chip 303 are provided on the circuit board 300. The optical matching chip 302 can be a bare chip such as a laser driver chip 3021 and / or a TIA chip 3022. The bare chip is bonded to the circuit board 300 with silver glue to fix and dissipate heat. Then, the bare chip is connected to the circuit board 300 by gold wire bonding. The optical chip 303 can be an optical transmitter chip 3031 and / or an optical receiver chip 3032. The optical transmitter chip 3031 and the optical receiver chip 3032 can be fixed side by side on the circuit board 300.

[0080] In some embodiments, the optical transceiver component 900 includes an optical fiber holder and a lens assembly, the optical fiber holder is optically connected to the lens assembly, and the lens assembly is covered on the optical matching chip 302 and the optical chip 303 on the circuit board 300 to place the optical matching chip 302 and the optical chip 303 in the covering cavity formed by the lens assembly and the circuit board.

[0081] Since the optical chip 303 is attached to the circuit board 300, its light-emitting surface or light-incident surface is located on the top surface of the optical chip 303, so the light beam emitted by the optical emitting chip 3031 is perpendicular to the circuit board 300, and the light beam received by the optical receiving chip 3032 is perpendicular to the circuit board 300; and the optical fiber 101 connected to the optical module is parallel to the circuit board 300, and the transmission direction of the light beam emitted by the optical emitting chip 3031 and the external light beam transmitted to the optical receiving chip 3032 needs to be changed. Therefore, the light beam emitted by the optical emitting chip 3031 is changed by the lens component, so that the light beam emitted by the optical emitting chip 3031 is reflected by the lens component, and the reflected light beam is parallel to the circuit board 300, so as to facilitate the coupling of the reflected light beam into the optical fiber; the receiving light beam transmitted by the external optical fiber is reflected by the lens component, and the reflected light beam is perpendicular to the circuit board 300, so as to facilitate the reception by the optical receiving chip 3032.

[0082] As shown in Figure 6, the circuit board 300 also includes a DSP chip 301, which is used for high-frequency signal processing. At the receiving end, the high-frequency signal received by the optical receiver chip 3032 is amplified by the TIA chip 3022 and then transmitted to the DSP chip 301 via a high-frequency signal line connecting the TIA chip 3022 and the DSP chip 301 for processing. The signal is then transmitted to the communication system via the gold finger. The transmitting end operates in the opposite direction. After receiving the signal at the gold finger, it is processed by the DSP chip 301. The processed signal is then transmitted to the laser driver chip 3021 via a signal line connecting the DSP chip 301 and the laser driver chip 3021. The processed signal is then transmitted to the optical transmitter chip 3031 for conversion into an optical signal. The optical signal emitted by the optical transmitter chip 3031 is coupled into an optical fiber through the lens assembly of the optical transceiver component 900 for transmission.

[0083] As communication rates increase, while power consumption per unit bandwidth decreases, the overall power consumption of optical modules continues to increase. Air cooling, the heat dissipation method used in client devices, is predominantly air cooling, which has reached its limits for high-speed transmission systems. To overcome this limitation, researchers are exploring various liquid cooling methods, one of which involves immersing the switch in a refrigerant such as fluorinated liquid (FC-40). However, due to cost-effectiveness requirements, optical modules deployed in data centers often use unsealed designs for their optical transmitter and receiver components, leaving their critical optical paths open. When the optical module enters the refrigerant along with the switch, these critical optical paths and components also enter the refrigerant, causing changes in the optical mechanism and contamination of the optical surfaces, seriously impacting the module's operation.

[0084] In some embodiments, to prevent coolant from seeping into the optical chip 303 and optical matching chip 302 within the lens assembly through the gap between the lens assembly and the circuit board 300, a first sealant is provided between the lens assembly and the circuit board 300 after the lens assembly cover is placed over the optical chip 303 and the optical matching chip 302. The first sealant is located between the outer wall of the lens assembly and the surface of the circuit board 300. That is, sealant is applied to the periphery of the contact point between the lens assembly and the circuit board 300 so that the sealant completely seals the gap between the lens assembly and the circuit board 300, and the sealant accumulates on the surface of the circuit board 300 and the outer wall of the lens assembly. After the sealant cures, the first sealant is formed. For example, the lens assembly can be a first lens assembly, with the first sealant provided between the first lens assembly and the circuit board 300; the lens assembly can be a second lens assembly, with the first sealant provided between the second lens assembly and the circuit board 300; and the lens assembly can be a third lens assembly, with the first sealant provided between the third lens assembly and the circuit board 300. In some embodiments, the sealing glue is an epoxy glue. The epoxy sealing glue has excellent chemical corrosion resistance, heat resistance and bonding properties, and can better prevent the coolant from penetrating.

[0085] The sealing glue of the epoxy system can be the first sealing glue, the second sealing glue, the third sealing glue, or the fourth sealing glue. The bonding strength of the first sealing glue, the third sealing glue, and the fourth sealing glue are all greater than the bonding strength of the second sealing glue. The viscosity of the first sealing glue is greater than the viscosity of the third sealing glue. The viscosity of the first sealing glue is greater than the viscosity of the fourth sealing glue. The viscosity of the third sealing glue is less than the viscosity of the fourth sealing glue.

[0086] In some embodiments, in order to prevent the cooling liquid from penetrating into the optical path between the lens assembly and the optical fiber holder through the gap between the lens assembly and the optical fiber holder, a second seal is provided between the optical fiber holder and the lens assembly after the optical fiber holder is inserted into the lens assembly.

[0087] For example, the lens assembly is provided with a snap-in groove, and the optical fiber holder is placed in the snap-in groove, that is, the three side surfaces of the snap-in groove are respectively provided to correspond to the side surfaces corresponding to the optical fiber holder, and the snap-in surface of the snap-in groove is provided to correspond to the first end surface of the optical fiber holder. After the optical fiber holder is placed in the snap-in groove, a first sealing glue is injected into the gap between the snap-in groove and the optical fiber holder (including the gaps between the three side surfaces of the snap-in groove and the side surfaces of the optical fiber holder, and the gap between the snap-in surface of the snap-in groove and the first end surface of the optical fiber holder). After the first sealing glue is cured, a second sealing member is formed to prevent the coolant from infiltrating through the gap between the optical fiber holder and the snap-in groove.

[0088] However, when the first sealing glue is injected into the gap between the clamping surface of the clamping groove and the first end face of the optical fiber holder (the side of the optical fiber holder facing the lens assembly), the first sealing glue may penetrate into the first end face of the optical fiber holder, and then penetrate into the optical path between the lens assembly and the optical fiber holder, affecting the total optical path of the optical transceiver component.

[0089] In order to solve this problem, a shielding member is provided to shield the gap between the lens assembly and the first end of the optical fiber bracket. A first sealing glue is applied on the outer wall of the shielding member so that the first end face of the optical fiber bracket is far away from the position of the first sealing glue, thereby making the first end face of the optical fiber bracket less likely to be contaminated by the first sealing glue.

[0090] In some embodiments, the shielding member is integrally formed with other structures of the lens assembly, the shielding member and the snap-fitting groove form a wrapping cavity, and the shielding member is a side wall of the wrapping cavity away from the circuit board.

[0091] In some other embodiments, the shielding member and other structures of the lens assembly are independent structural members. The shielding member is a sealing cover plate, one end of which is covered on the optical fiber bracket, and the other end of the sealing cover plate is covered on the optical port groove.

[0092] FIG7 is a structural diagram of the first optical transceiver component provided in an embodiment of the present disclosure. FIG8 is a decomposition diagram of the first optical transceiver component provided in an embodiment of the present disclosure. FIG9 is a cross-sectional view of the first optical transceiver component provided in an embodiment of the present disclosure. As shown in FIG7, FIG8 and FIG9, in some embodiments, the first optical transceiver component 901 includes a first lens assembly 911 and an optical fiber bracket 912, and a wrapping cavity 9112 is provided at one end of the first lens assembly 911, and an opening is provided on one side of the wrapping cavity 9112. An optical fiber 9127 is fixed to one end of the optical fiber bracket 912, and the optical fiber bracket 912 carries the optical fiber 9127 and is inserted into the wrapping cavity 9112 through the opening to achieve connection between the optical fiber bracket 912 and the first lens assembly 911.

[0093] After inserting the optical fiber holder 912 into the wrapping cavity 9112, the wrapping cavity 9112 wraps around the optical fiber holder 912, embedding the first end face of the optical fiber holder 912 within the wrapping cavity 9112. A first sealant is applied to the adhesive dispensing surface 91124 of the wrapping cavity 9112, positioning the first end face of the optical fiber holder 912 at a greater distance from the first sealant. This reduces the risk of contamination by the first sealant. After the first sealant cures, a second sealant is formed, located on the side of the optical fiber holder 912 and around the adhesive dispensing surface 91124 of the wrapping cavity 9112, to isolate the coolant. That is, after inserting the optical fiber holder 912 into the wrapping cavity 9112, the first sealing glue is applied to the glue dispensing surface 91124 of the wrapping cavity 9112 so that the first sealing glue can completely seal the gap between the wrapping cavity 9112 and the optical fiber holder 912. The first sealing glue is accumulated between the wrapping cavity 9112 and the optical fiber holder 912. After the first sealing glue is cured, a second sealing member is formed to ensure the sealing of the connection between the first lens assembly 911 and the optical fiber holder 912, thereby preventing the infiltration of coolant.

[0094] After the optical fiber holder 912 is inserted into the wrapping cavity 9112, the four side surfaces of the optical fiber holder 912 are respectively arranged corresponding to the four side walls corresponding to the wrapping cavity 9112, and the first end face of the optical fiber holder 912 is arranged corresponding to the clamping wall of the wrapping cavity 9112. The clamping wall of the wrapping cavity 9112 is located deep in the wrapping cavity 9112, away from the glue spot surface 91124 of the wrapping cavity 9112, that is, the first end face of the optical fiber holder 912 is located in the wrapping cavity 9112, away from the glue spot surface 91124 of the wrapping cavity 9112.

[0095] A first lens 9116 is provided in the wrapping cavity 9112. The first lens 9116 is provided corresponding to the optical fiber bracket 912. The first lens 9116 includes a receiving collimating lens and an emitting coupling lens. The emitting coupling lens couples the light beam emitted by the first lens assembly 911, and the receiving collimating lens collimates the light beam of the optical fiber 9127 in the optical fiber bracket 912.

[0096] When coupling and mounting the first lens assembly 911 on the circuit board 300, a gap needs to be created between the first lens assembly 911 and the circuit board 300. For example, a suction nozzle can be used to hold the first lens assembly 911, creating a gap between the first lens assembly 911 and the circuit board 300, and then coupling with the optical chip on the circuit board 300 can be performed. If the top surface of the first lens assembly 911 is uneven or lacks a sufficiently large flat surface, there will be no place to place the suction nozzle on the top surface of the first lens assembly 911. Therefore, it is necessary to provide a larger suction surface on the top surface of the first lens assembly 911 to place the suction nozzle, so that the suction nozzle can hold the first lens assembly 911.

[0097] In some embodiments, the top surface of the area of ​​the first lens assembly 911 corresponding to the wrapping cavity 9112 is flush with the top surface of the area of ​​the first lens assembly 911 other than the wrapping cavity 9112. In other words, the top surface of the first lens assembly 911 is a flat surface during manufacturing, and the wrapping cavity 9112 can be a groove formed on the side wall of the first lens assembly 911 by demolding or milling. The flush top surface can provide a larger adsorption plane for the suction nozzle to facilitate the suction nozzle to absorb the first lens assembly 911.

[0098] As shown in Figures 7, 8 and 9, an optical port slot 9111 is provided on the area of ​​the first lens assembly 911 except for the wrapping cavity 9112. The top surface of the optical port slot 9111 (the plane facing away from the circuit board 300) is provided with an opening, and the other end of the slot wall of the optical port slot 9111 (the end close to the circuit board 300) is formed with a reflecting surface 9115. The reflecting surface 9115 is arranged opposite to the first lens 9116, so that the optical signal emitted by the optical chip 303 (specifically the optical transmitting chip 3031) is reflected by the reflecting surface 9115, and the reflected light beam is emitted through the first lens 9116. The first lens 9116 reflects the light beam transmitted by the received optical fiber through the reflecting surface 9115, and the reflected light signal is incident on the optical chip 303 (specifically the optical receiving chip 3032).

[0099] The wrapping cavity 9112 wraps around each side of the optical fiber holder 912, increasing the thickness of the right side of the first lens assembly 911 (i.e., the end connected to the optical fiber holder 912). If the thickness of the left side of the first lens assembly 911 (i.e., the end not connected to the optical fiber holder 912) is not increased, it is easy to cause a large difference in the thickness ratio of the first lens assembly 911. Therefore, it is necessary to increase the thickness of the left side of the first lens assembly 911, that is, to increase the thickness of the area of ​​the first lens assembly 911 other than the wrapping cavity 9112 (the distance between the upper surface of the first lens assembly 911 and the lower surface of the first lens assembly 911). The thickness of the area of ​​the first lens assembly 911 other than the wrapping cavity 9112 is increased, while the height of the position where the first lens 9116 is mounted does not change. In order to enable the reflective surface 9115 to reflect the optical signal to the first lens 9116, in some embodiments, the depth of the optical port groove 9111 is increased. The depth of the optical port groove 9111 increases, and the distance between the opening of the optical port groove 9111 and the reflecting surface 9115 increases, thereby reducing the amount of sealing material that penetrates into the reflecting surface 9115 through the opening of the optical port groove 9111.

[0100] For example, when the top surface of the area of ​​the first lens assembly 911 excluding the wrapping cavity 9112 is higher than the top surface of the area of ​​the first lens assembly 911 corresponding to the wrapping cavity 9112, the depth of the light opening groove 9111 is 1.8-2.2 mm; when the top surface of the area of ​​the first lens assembly 911 corresponding to the wrapping cavity 9112 is flush with the top surface of the area of ​​the first lens assembly 911 excluding the wrapping cavity 9112, the depth of the light opening groove 9111 is less than 1 mm.

[0101] In order to prevent the coolant from penetrating into the reflective surface 9115, in some embodiments, a rubber-isolating protrusion is provided at one end of the groove wall of the optical port groove 9111, and a large number of third sealing members are provided on the rubber-isolating protrusion. The rubber-isolating protrusion narrows the optical port groove 9111 to form a deep well groove. A first sealing glue is injected into the opening of the optical port groove 9111 to seal the opening of the optical port groove 9111, isolating the external coolant from the reflective surface of the optical port groove 9111, and preventing the coolant from penetrating into the reflective surface inside the optical port groove 9111; because the first sealing glue is viscous, the first sealing glue can only cover the upper part of the deep well groove (i.e., the rubber-isolating protrusion of the optical port groove 9111), and the air in the lower part of the deep well groove supports the first sealing glue, so that the first sealing glue cannot flow downward onto the reflective surface 9115, thereby ensuring that the reflective surface 9115 is isolated from the external coolant and is not affected by the first sealing glue.

[0102] Since the top surface of the optical port slot 9111 is provided with an opening to facilitate demolding of the plastic mold, in some embodiments, a blocking assembly is provided on the top surface of the optical port slot 9111 at the opening to prevent coolant from seeping into the reflective surface 9115 through the opening of the optical port slot 9111. The blocking assembly is fixed to the top surface of the optical port slot 9111 to seal the opening of the optical port slot 9111, thereby preventing coolant from seeping through the opening of the optical port slot 9111.

[0103] In some embodiments, the blocking assembly includes a partial sealing cover plate, one end of the sealing cover plate covers the optical fiber bracket, and the other end of the sealing cover plate covers the optical port slot 9111 to seal the opening of the optical port slot 9111.

[0104] In some other embodiments, the blocking assembly includes a blocking piece 913 , which is fixed to the top surface of the optical port slot 9111 to seal the opening of the optical port slot 9111 .

[0105] In some embodiments, the side of the baffle 913 facing the optical port slot 9111 is coated with adhesive, and the baffle 913 is adhered to the top surface of the optical port slot 9111 through the adhesive to fix the baffle 913 to the top surface of the optical port slot 9111.

[0106] In some embodiments, the material of the blocking sheet 913 includes, but is not limited to, polyimide.

[0107] The size of the baffle 913 is larger than the opening size of the optical port slot 9111, so that the baffle 913 can completely block the opening of the optical port slot 9111. After the opening of the optical port slot 9111 is sealed by the baffle 913, a first sealing glue can be added to the side of the baffle 913, that is, the first sealing glue is added to the connection between the baffle 913 and the surface of the first lens assembly 911. After the first sealing glue is cured, a third sealing member is formed. The third sealing member seals the opening between the baffle 913 and the optical port slot 9111 to reduce the infiltration of coolant into the optical port slot 9111 and ensure that the optical port slot 9111 is isolated from the coolant.

[0108] However, the blocking piece 913 is only bonded to the opening of the optical port slot 9111 by adhesive, which has insufficient adhesive strength. This results in poor connection stability between the blocking piece 913 and the opening of the optical port slot 9111, and further results in poor sealing between the blocking piece 913 and the opening of the optical port slot 9111, i.e., the blocking piece 913 and the opening of the optical port slot 9111 cannot be completely sealed. In order to achieve a complete seal between the blocking piece 913 and the opening of the optical port slot 9111, in some embodiments, a first sealing adhesive is applied above and around the blocking piece 913. That is, the first sealing glue is added above the baffle 913, at the connection between the baffle 913 and the surface of the first lens assembly 911, and on the surface of the first lens assembly 911. After the first sealing glue is cured, a third sealing member is formed. The third sealing member completely seals the opening between the baffle 913 and the optical port groove 9111, further reducing the infiltration of the cooling liquid into the optical port groove 9111, and further ensuring that the optical port groove 9111 is isolated from the cooling liquid.

[0109] Because the first sealant can move, this movement can easily result in the third sealant, after the first sealant has cured, being unable to fully seal the baffle 913 from the opening of the optical port slot 9111. To address this issue, in some embodiments, a storage groove is provided outside the optical port slot 9111. Specifically, the storage groove is formed on the top surface of the first lens assembly 911, with the optical port slot 9111 located at the bottom of the storage groove. The storage groove contains the optical port slot 9111, the baffle 913, and a third sealant, with the third sealant located on the top and outer sidewalls of the baffle 913. The first sealant is injected into the storage groove so that it covers the top of the baffle 913, the junction between the baffle 913 and the surface of the first lens assembly 911, and the surface of the first lens assembly 911. After the first sealant cures, the third sealant is formed. The third sealant is located on the top and outer sidewalls of the baffle 913 to ensure a stable connection between the baffle 913 and the storage groove. The storage groove can limit the third seal to a preset position to prevent the third seal from deviating from the preset position, so as to achieve complete sealing between the baffle 913 and the opening of the optical port groove 9111, and further ensure that the optical port groove 9111 is isolated from the coolant.

[0110] In some embodiments, a storage groove is provided on the outside of the optical port slot 9111. The storage groove contains the optical port slot 9111, a baffle 913, and a third sealing member. A rubber barrier protrusion is provided at one end of the slot wall of the optical port slot 9111. The storage groove secures the third sealing member in a predetermined position, thereby completely sealing the baffle 913 from the opening and preventing coolant from seeping in. The first sealing glue in the storage groove seeps into the rubber barrier protrusion of the optical port slot 9111, coating the first sealing glue. The air in the lower portion of the deep well supports the first sealing glue, preventing it from flowing downward onto the reflective surface 9115. This ensures that the reflective surface 9115 is both isolated from the external coolant and unaffected by the first sealing glue.

[0111] In some embodiments, a storage groove is provided on the outside of the optical port slot 9111. The storage groove contains the optical port slot 9111, a baffle 913, and a third sealing member. A rubber barrier protrusion is provided at one end of the slot wall of the optical port slot 9111, and a large number of third sealing members are provided on the rubber barrier protrusion. The storage groove can fix the third sealing member in a preset position to achieve a complete seal between the baffle 913 and the opening, preventing the infiltration of coolant. The first sealing glue in the storage groove seeps into the first sealing glue in the optical port slot 9111, and the first sealing glue in the optical port slot 9111 is coated on the rubber barrier protrusion. The air in the lower portion of the deep well groove supports the first sealing glue, preventing the first sealing glue from flowing downward onto the reflective surface 9115, thereby ensuring that the reflective surface 9115 is both isolated from the external coolant and unaffected by the first sealing glue. In some embodiments, the optical module includes two sets of staggered optical transceiver components. When the two optical transceiver components are placed too close to each other, the optical fiber connecting one optical transceiver component needs to cross the other optical transceiver component. This can easily cause the bending radius of the optical fiber to be too small, affecting optical fiber transmission. To solve this problem, the first lens assembly 911 is provided with an inclined surface 9113. The inclined surface 9113 is inclined along the top surface of the first lens assembly 911 toward the side of the first lens assembly 911 away from the optical fiber bracket 912, that is, the inclined surface 9113 is an inclined surface inclined downward. The rear optical fiber is tilted upward along the inclined surface 9113, so that the optical fiber has a larger bending radius, avoiding the optical fiber transmission problem caused by the optical fiber radius being too small.

[0112] As shown in Figure 9, a cover cavity 9124 is provided on the side of the first lens assembly 911 facing the circuit board 300. The cover cavity 9124 is recessed from the bottom surface to the top surface of the first lens assembly 911. In this way, when the first lens assembly 911 is sealed and installed with the circuit board 300, the cover cavity 9124 forms a sealed cavity. Optoelectronic devices such as the optical chip 303 and the optical matching chip 302 are located in the sealed cavity, which can prevent coolant from seeping into the first lens assembly 911 and causing failure of optoelectronic devices such as the optical chip 303 and the optical matching chip 302.

[0113] A second lens 9117 is provided on the inner sidewall of the housing cavity 9124. The second lens 9117 is located below the reflective surface 9115, and the optical chip 303 is located below the second lens 9117. The second lens 9117 can be a transmitting collimating lens, and the optical chip 303 can be a light transmitting chip. In this case, the light beam emitted by the light transmitting chip is converted into a collimated light beam via the transmitting collimating lens. The collimated light beam is then reflected by the reflective surface 9115. The reflected collimated light beam is then converted into a convergent light beam via the first lens 9116 and coupled to the optical fiber. The second lens can also be a receiving coupling lens, and the optical chip 303 can be a light receiving chip. In this case, the received light beam is transmitted to the reflective surface 9115 via the first lens 9116. The received light beam is reflected by the reflective surface 9115, and the reflected received light beam is coupled to the light receiving chip via the receiving coupling lens.

[0114] After the first sealing glue seals the gap between the first lens assembly 911 and the circuit board 300, the optical module needs to be placed in a high temperature environment. After the first sealing glue seals the gap between the wrapping cavity 9112 and the optical fiber bracket 912, the optical module also needs to be placed in a high temperature environment. At high temperatures, the air in the cavity sealed by the first sealing glue will expand. If there is no release hole, the expanded air will push out an air hole in the uncured first sealing glue, causing the coolant to penetrate. Therefore, an air vent 9119 is also provided on the first lens assembly 911, and the air vent 9119 is connected to the cover cavity 9124 or the wrapping cavity 9112. The expanded air in the cover cavity 9124 or the wrapping cavity 9112 is released through the air vent 9119, and the air vent 9119 is filled with the second sealing glue. After the second sealing glue is cured, a twelfth seal is formed. The twelfth seal blocks the air vent 9119 to prevent the coolant from penetrating into the first lens assembly 911 through the air vent 9119.

[0115] Figure 10 is an assembly diagram of the first lens assembly and the baffle according to an embodiment of the present disclosure. Figure 11 is an exploded view of the first lens assembly and the baffle according to an embodiment of the present disclosure. Figure 12 is a structural diagram of the first lens assembly according to an embodiment of the present disclosure from a first viewing angle. As shown in Figures 10, 11, and 12, in some embodiments, the storage slot includes a first storage slot 9120, within which is disposed a baffle 913 and a third sealing member. The third sealing member is located on the top and outer sidewalls of the baffle 913. After the baffle 913 is attached to the first storage slot 9120, the first storage slot 9120 is filled with a first sealing adhesive. The first sealing adhesive is filled to a higher level than the baffle, so that the first sealing adhesive accumulates on top of the baffle 913. After the first sealing adhesive cures, the third sealing member is formed. The first storage slot 9120 defines the position of the third sealing member on the surface of the first lens assembly 911, preventing the third sealing member from deviating from the preset position and ensuring a stable connection between the baffle 913 and the opening of the optical port slot 9111.

[0116] The depth dimension of the first storage groove 9120 and the height dimension of the third seal are both greater than the thickness dimension of the baffle 913, the length dimension of the first storage groove 9120 is greater than the length dimension of the baffle 913, or the width dimension of the first storage groove 9120 is greater than the width dimension of the baffle 913, so that the third seal is located on the top and outer wall of the baffle 913.

[0117] In some embodiments, the storage slot further includes a second storage slot 9121, which is formed by an inward depression of the first storage slot 9120. The first storage slot 9120 includes a third sealant and a second storage slot 9121. A baffle 913 is placed in the second storage slot 9121, and the third sealant is located on the top and outer sidewall of the baffle 913. After the baffle 913 is attached to the second storage slot 9121, the first storage slot 9120 is filled with a first sealant, so that the first sealant accumulates on the top of the baffle 913. After the first sealant cures, the third sealant is formed. The second storage slot 9121 defines the position of the baffle 913 on the surface of the first lens assembly 911, preventing the baffle 913 from deviating from the preset position, so that the baffle 913 completely covers the opening of the optical port slot 9111, thereby achieving a stable connection between the baffle 913 and the second storage slot 9121.

[0118] The length of the second storage groove 9121 can be greater than the length of the baffle 913, or the width of the second storage groove 9121 can be greater than the width of the baffle 913, so that the baffle 913 and the third sealing member can be placed in the second storage groove 9121. After the baffle 913 is attached to the second storage groove 9121, the first sealing glue is injected into the gap between the baffle 913 and the second storage groove 9121, and the first storage groove 9120 is filled with the first sealing glue so that the first sealing glue accumulates on the outer wall and top of the baffle 913. After the first sealing glue cures, the third sealing member is formed.

[0119] Of course, in addition to the aforementioned arrangement of the first storage groove 9120 and the second storage groove 9121, an annular storage groove may also be provided around the opening of the optical port slot 9111, that is, a certain distance exists between the opening of the optical port slot 9111 and the annular storage groove. Accordingly, a baffle covering the optical port slot 9111 has the same dimensions as the area enclosed by the annular storage groove, and the baffle has an annular protrusion extending toward the bottom surface of the annular storage groove. During assembly, the baffle with the annular protrusion can be snapped into the annular storage groove, and a first sealing adhesive is applied within the annular storage groove. After the sealing adhesive cures, a third sealing member is formed, thereby sealing the baffle protrusion into the annular storage groove, thereby sealing the optical port slot 9111.

[0120] As shown in Figures 9, 10, 11, and 12, in some embodiments, the sealant protrusions include first sealant protrusions 9122. These protrusions 9122 are formed by protruding outward from the walls of the optical port slot 9111. These first sealant protrusions 9122 narrow the optical port slot 9111, forming a deep well. Due to the high viscosity of the first sealant, it can only coat the first sealant protrusions 9122 at the upper portion of the deep well. The air below the deep well supports the first sealant, preventing it from flowing downward onto the reflective surface 9115. This ensures that the reflective surface 9115 is both isolated from the external coolant and unaffected by the first sealant.

[0121] In some embodiments, the first rubber spacer protrusion 9122 is formed by a groove wall of the optical port groove 9111 protruding outward. The first rubber spacer protrusion 9122 is a non-closed annular protrusion, and the non-closed annular protrusion and the opening of the optical port groove 9111 form a step.

[0122] In some embodiments, the first rubber spacer protrusion 9122 is formed by all the groove walls of the optical port groove 9111 protruding outward. The first rubber spacer protrusion 9122 is a closed annular protrusion, and the closed annular protrusion and the opening of the optical port groove 9111 form a step.

[0123] In some embodiments, the first rubber spacer protrusion 9122 is formed by all the groove walls of the optical port groove 9111 protruding outward. The first rubber spacer protrusion 9122 includes multiple closed annular protrusions, and the multiple closed annular protrusions are connected in sequence. The sizes of the multiple closed annular protrusions are different. The multiple closed annular protrusions form N1 steps from small to large according to their sizes. The N1 step and the opening of the optical port groove 9111 form N1+1 steps, and N1≥2.

[0124] The closed annular protrusion with the same width narrows the size of the light opening groove 9111 compared to the non-closed annular protrusion with the same width, and the capacity of the first sealing glue that can be carried is increased. Therefore, the reflective surface of the first lens assembly 911 with the closed annular protrusion is less susceptible to the influence of external coolant and the first sealing glue than the first lens assembly 911 with the non-closed annular protrusion.

[0125] The maximum width dimension of the multiple closed annular protrusions is the same as the width dimension of a single closed annular protrusion. Compared with a single closed annular protrusion, the multiple closed annular protrusions narrow the size of the optical opening groove 9111, and the capacity of the first sealing glue that can be carried is increased. Therefore, the reflective surface of the first lens assembly 911 with multiple closed annular protrusions is less susceptible to the influence of external coolant and the first sealing glue than the first lens assembly 911 with a single closed annular protrusion.

[0126] In some embodiments, the sealant protrusions further include a second sealant protrusion 9123. This second sealant protrusion 9123 is formed by protruding outward from the first groove wall (referring to the groove wall where the reflective surface of the optical port groove 9111 is located) where the first sealant protrusion 9122 is located. This second sealant protrusion 9123 further narrows the optical port groove 9111, forming a deep well groove. Due to the viscosity of the first sealant, it can only coat the first sealant protrusion 9122 and the second sealant protrusion 9123 in the upper portion of the deep well groove. The air below the deep well groove supports the first sealant, preventing it from flowing downward onto the reflective surface 9115. This ensures that the reflective surface 9115 is both isolated from the external coolant and unaffected by the first sealant.

[0127] In some embodiments, the second rubber spacer protrusion 9123 is formed by the outward protrusion of the first groove wall of the optical port groove 9111. The second rubber spacer protrusion 9123 is a non-closed annular protrusion. The non-closed annular protrusion, the first rubber spacer protrusion 9122 and the opening of the optical port groove 9111 form M steps, and M is greater than 2.

[0128] In some embodiments, the second rubber spacer protrusion 9123 is formed by the outward protrusion of the first groove wall of the optical port groove 9111. The second rubber spacer protrusion 9123 includes a plurality of non-closed annular protrusions, which are connected in sequence. The sizes of the plurality of non-closed annular protrusions are different. The plurality of non-closed annular protrusions form N2 steps from small to large according to their sizes. The N2 steps, the first rubber spacer protrusion 9122 and the opening of the optical port groove 9111 form N1+N2+1 steps, where N1≥2 and N2≥2.

[0129] As shown in Figure 12, in some embodiments, the reflection surface 9115 includes an emitting reflection surface 9115a and a receiving reflection surface 9115b. The emitting reflection surface 9115a is set corresponding to the emitting collimating lens and the light emitting chip 3031, and the receiving reflection surface 9115b is set corresponding to the receiving coupling lens and the light receiving chip 3032. The optical signal emitted by the light emitting chip 3031 is reflected by the emitting reflection surface 9115a, and the reflected optical signal is emitted through the first lens 9116. The first lens 9116 reflects the optical signal transmitted by the optical fiber through the receiving reflection surface 9115b, and the reflected optical signal is incident on the light receiving chip 3032.

[0130] In some embodiments, there is only one optical port slot 9111, with no distinction between a transmitting optical port slot and a receiving optical port slot. This optical port slot is provided with a first rubber spacer protrusion 9122, a second rubber spacer protrusion 9123, and a reflective surface 9115. The reflective surface 9115 includes an emitting reflective surface 9115a and a receiving reflective surface 9115b, which are connected. The first lens assembly 911 is provided with only one optical port slot 9111, facilitating processing.

[0131] In some other embodiments, the optical port slot 9111 includes an emission optical port slot 9111a and a receiving optical port slot 9111b, with the emission optical port slot 9111a and the receiving optical port slot 9111b being separated. An emission septum protrusion is provided within the emission optical port slot 9111a, and a receiving septum protrusion is provided within the receiving optical port slot 9111b. The emission septum protrusion and the receiving septum protrusion are not connected. The emission septum protrusion includes a first emission septum protrusion 9122a. A second emission septum protrusion 9123a protruding outward is provided at one end of the first slot wall where the first emission septum protrusion 9122a is located. The other end of the first slot wall where the first emission septum protrusion 9122a is located forms an emission reflection surface 9115a. The first emission septum protrusion 9122a and the second emission septum protrusion 9123a are stepped to narrow the emission optical port slot 9111a. The receiving rubber spacer protrusion includes a first receiving rubber spacer protrusion 9122b. A second receiving rubber spacer protrusion 9123b protruding outward is provided at one end of the first groove wall where the first receiving rubber spacer protrusion 9122b is located. A receiving reflective surface 9115b is formed at the other end of the first groove wall where the first receiving rubber spacer protrusion 9122b is located. The first receiving rubber spacer protrusion 9122b and the second receiving rubber spacer protrusion 9123b are stepped to narrow the receiving light port groove 9111b. The emitting reflective surface 9115a and the receiving reflective surface 9115b are not connected.

[0132] The first lens assembly 911 is provided with an emitting light port slot 9111a and a receiving light port slot 9111b, which are separated from the emitting light port slot 9111a and the receiving light port slot 9111b, further narrowing the light port slot 9111, thereby ensuring that the first sealing glue cannot flow down to the reflecting surface 9115, thereby ensuring that the reflecting surface 9115 is isolated from the coolant and is not affected by the first sealing glue.

[0133] FIG13 is a structural diagram of the first lens assembly provided by an embodiment of the present disclosure at a second viewing angle. FIG14 is a structural diagram of the optical fiber bracket provided by an embodiment of the present disclosure. As shown in FIG13 and FIG14, in some embodiments, the wrapping cavity 9112 includes a first wrapping side wall 91121, a snap-fit ​​wall 91122, a second wrapping side wall 91123, a third wrapping side wall and a fourth wrapping side wall. The first wrapping side wall 91121, the snap-fit ​​wall 91122, the second wrapping side wall 91123, the third wrapping side wall and the fourth wrapping side wall form a wrapping cavity 9112 with an opening. The first wrapping side wall 91121 is arranged opposite to the fourth wrapping side wall. The second wrapping side wall 91123 and the third wrapping side wall are arranged opposite to the fourth wrapping side wall. The walls are arranged relative to each other, the snap-fitting wall 91122 is arranged opposite to the opening of the wrapping cavity 9112, the first wrapping side wall 91121 and the fourth wrapping side wall are respectively connected to the snap-fitting wall 91122, the second wrapping side wall 91123 and the third wrapping side wall, the second wrapping side wall 91123 and the third wrapping side wall are also respectively connected to the snap-fitting wall 91122, the snap-fitting wall 91122 is provided with a first positioning column 9118 and a first groove 9114 recessed toward the reflecting surface 9115, and a first lens 9116 is provided in the first groove 9114.

[0134] The outer side surface 91125 of the first wrapping side wall 91121, the outer side surface of the second wrapping side wall 91123, the outer side surface of the third wrapping side wall, and the fourth wrapping side wall constitute the glue-dispensing surface 91124 of the wrapping cavity 9112. A first sealant is applied to the glue-dispensing surface 91124, and the first sealant is allowed to cure to form a second sealant. The second sealant is located on each side surface of the optical fiber holder 912 and around the glue-dispensing surface 91124 of the wrapping cavity 9112. Specifically, the first sealant is applied to the outer side surface 91125 of the first wrapping side wall 91121, the outer side surface of the second wrapping side wall 91123, the outer side surface of the third wrapping side wall, and the fourth wrapping side wall, and the first sealant is allowed to cure to form a second sealant. The second sealant is located on each side surface of the optical fiber holder 912 and around the outer side surfaces of the first wrapping side wall 91121, the outer side surface of the second wrapping side wall 91123, the outer side surface of the third wrapping side wall, and the fourth wrapping side wall.

[0135] The first wrapping sidewall 91121 is a sidewall of the wrapping cavity 9112 away from the circuit board 300, and the fourth wrapping sidewall is a sidewall of the wrapping cavity 9112 close to the circuit board 300. Thus, the outer side surfaces of the three sidewalls of the wrapping cavity 9112 away from the circuit board 300 and the one sidewall of the wrapping cavity 9112 close to the circuit board 300 form the glue dispensing surface 91124 of the wrapping cavity 9112. In other words, the second sealing member is located between each side surface of the optical fiber holder 912 and the outer side surfaces of the three sidewalls of the wrapping cavity 9112 away from the circuit board 300, as well as around the one sidewall of the wrapping cavity 9112 close to the circuit board 300.

[0136] In some embodiments, the outer surface of the second wrapping sidewall 91123 includes a first outer portion 91126 and a second outer portion 91127. The first outer portion 91126 is connected to the second outer portion 91127. The first outer portion 91126 is also connected to the outer surface 91125 of the first wrapping sidewall 91121. The first outer portion 91126 is located between the outer surface 91125 and the second outer portion 91127 of the first wrapping sidewall 91121. The outer surface 91125 of the first wrapping sidewall 91121 and the first outer portion 91126 are vertical surfaces, while the second outer portion 91127 is an inclined surface. It will be understood that the inclined surface of the second outer portion 91127 facilitates the application of the first sealant between the second wrapping sidewall 91123 and the side of the optical fiber holder 912.

[0137] The second wrapping side wall 91123 and the third wrapping side wall are two symmetrically arranged structural members, which will not be described in detail here.

[0138] As shown in Figure 14, the first end face of the optical fiber bracket 912 (the side of the optical fiber bracket 912 facing the first groove 9114) is provided with a penetrating first positioning hole 9126, and the first positioning hole 9126 is arranged opposite to the first positioning column 9118. In this way, when the optical fiber bracket 912 is inserted into the wrapping cavity 9112, the first positioning column 9118 is inserted into the first positioning hole 9126 to position and install the optical fiber bracket 912.

[0139] Of course, a first positioning column can also be set on the first end face of the optical fiber bracket 912, and a first positioning hole adapted to the first positioning column can be formed on the clamping wall 91122 of the wrapping cavity 9112 to achieve positioning and installation between the optical fiber bracket 912 and the lens assembly.

[0140] The first end face of the optical fiber holder 912 is also provided with an optical fiber hole, and the second end face of the optical fiber holder 912 (the opposite side of the first end face of the optical fiber holder 912) is provided with an optical fiber jack, which is connected to the optical fiber jack, so that the optical fiber 9127 is inserted into the optical fiber hole through the optical fiber jack, and the light incident surface of the optical fiber 9127 can be located inside the optical fiber holder 912, or it can protrude from the first end face of the optical fiber holder 912.

[0141] Insert the optical fiber 9127 into the optical fiber holder 912 through the optical fiber jack, and use the first sealing glue to seal all the gaps between the optical fiber 9127 and the optical fiber jack. The first sealing glue is added to the periphery of the contact point between the optical fiber 9127 and the optical fiber jack, and is accumulated on the second end face of the optical fiber 9127 and the optical fiber holder 912. After the first sealing glue is cured, a fourth sealing member is formed to prevent the cooling liquid from extending into the interior of the optical fiber holder 912 from the optical fiber jack.

[0142] As shown in FIG14 , the top surface of the optical fiber holder 912 is further provided with an observation hole 9125, which is in communication with the optical fiber hole in the optical fiber holder 912. The insertion of the optical fiber 9127 into the optical fiber holder 912 can be viewed through the observation hole 9125. After the optical fiber 9127 is inserted into the optical fiber holder 912 through the optical fiber insertion hole, a first sealant can be applied to the observation hole 9125 to form a seal, thereby sealing the observation hole 9125 and preventing coolant from seeping into the interior of the optical fiber holder 912 through the observation hole 9125.

[0143] In some embodiments, the first wrapping side wall 91121, the second wrapping side wall 91123, the third wrapping side wall and the fourth wrapping side wall are respectively arranged corresponding to the side surfaces corresponding to the optical fiber bracket 912, and the clamping wall 91122 is arranged corresponding to the first end surface of the optical fiber bracket 912 to realize that the wrapping cavity 9112 wraps the optical fiber bracket 912.

[0144] In some embodiments, the length of the first wrapping side wall 91121 is less than or equal to the length of a side surface of the optical fiber bracket 912 corresponding to the first wrapping side wall 91121. The dispensing needle can be placed directly on the optical fiber bracket 912 to facilitate the dispensing needle to dispense glue into the gap between the first wrapping side wall 91121 and the optical fiber bracket 912.

[0145] In some embodiments, the length dimension of the fourth wrapping side wall is smaller than the length dimension of a side surface of the optical fiber holder 912 corresponding to the fourth wrapping side wall. For example, the area of ​​the optical fiber holder 912 other than the optical fiber 9127 is partially located outside the wrapping cavity 9112.

[0146] In some embodiments, the length dimension of the fourth wrapping side wall is greater than or equal to the length dimension of a side surface corresponding to the fourth wrapping side wall in the optical fiber holder 912, that is, the area in the optical fiber holder 912 except the optical fiber 9127 is located in the wrapping cavity 9112, and the dispensing needle can be directly placed on the fourth wrapping side wall of the wrapping cavity 9112 to facilitate dispensing glue in the gap between the fourth wrapping side wall and the optical fiber holder 912.

[0147] Since the length dimension of the side surface corresponding to the first wrapping side wall 91121 in the optical fiber bracket 912 is the same as the length dimension of the side surface in contact with the fourth wrapping side wall in the optical fiber bracket 912, the length dimension of the first wrapping side wall 91121 is smaller than the length dimension of the fourth wrapping side wall, which not only can completely wrap the optical fiber bracket 912, but also makes it easier for the dispensing needle to dispense glue into the gap between the wrapping cavity 9112 and the optical fiber bracket 912.

[0148] FIG15 is a first structural diagram of the first lens assembly provided by an embodiment of the present disclosure at a third viewing angle. As shown in FIG15 , in some embodiments, the air vent 9119 includes a first air vent 9119a and a second air vent 9119b. The first air vent 9119a is located above the wrapping cavity 9112, and the second air vent 9119b is located above the cover cavity. The first air vent 9119a is connected to the wrapping cavity 9112, and the second air vent 911b is connected to the cover cavity 9124. The air expanding in the cover cavity 9124 is released through the second air vent 911b, filling the second air vent 9119b with a second sealing glue. The second sealing glue solidifies to form a twelfth sealing member, which blocks the second air vent 9119b to prevent coolant from seeping into the cover cavity 9124 through the second air vent 9119b.

[0149] The expanded air in the wrapping cavity 9112 is released through the first air vent 9119a, and the first air vent 9119a is filled with the second sealing glue. The second sealing glue solidifies to form a twelfth sealing member, which blocks the first air vent 9119a to prevent the coolant from penetrating into the wrapping cavity 9112 through the first air vent 9119a.

[0150] In some embodiments, the second seal extends within the gap between the first wrapping side wall 91121 and the top surface of the optical fiber bracket 912 without exceeding the first air hole 9119a. In other words, the first air hole 9119a is provided on the first wrapping side wall 91121 corresponding to the second seal and the clamping wall 91122, that is, the second seal does not block the first air hole 9119a, so that the expanded air in the wrapping cavity 9112 can be released through the first air hole 9119a.

[0151] FIG16 is a second structural diagram of the first lens assembly provided by an embodiment of the present disclosure at a third viewing angle. As shown in FIG16 , in some embodiments, the air vent 9119 includes a second air vent 9119b and a vent 9119c. The second air vent 9119b is located above the housing cavity 9124, and the vent 9119c is located below the wrapping cavity 9112. The second air vent 9119b is connected to the housing cavity 9124. The expanding air in the housing cavity 9124 is released through the second air vent 9119b. The expanding air in the wrapping cavity 9112 is released into the housing cavity 9124 through the vent 9119c, and then released out through the second air vent 9119b. The second air vent 9119b is filled with a second sealing glue, which solidifies to form a twelfth sealing member. The twelfth sealing member seals the second air vent 911b to prevent coolant from seeping into the housing cavity 9124.

[0152] FIG17 is a third structural diagram of the first lens assembly provided by an embodiment of the present disclosure at a third viewing angle. As shown in FIG14 and FIG17 , in some embodiments, the air vent 9119 includes a first air vent 9119a and a vent 9119c. The first air vent 9119a is located above the wrapping cavity 9112, and the vent 9119c is located below the wrapping cavity 9112. The first air vent 9119a is in communication with the wrapping cavity 9112. The air expanding within the housing cavity 9124 is released into the wrapping cavity 9112 through the vent 9119c and then released out through the first air vent 9119a. The air expanding within the wrapping cavity 9112 is released out through the first air vent 9119a, filling the first air vent 9119a with a second sealing adhesive. The second sealing adhesive solidifies to form a twelfth sealing member, which blocks the first air vent 9119a to prevent coolant from seeping into the housing cavity 9124.

[0153] As shown in Figures 15, 16 and 17, the second lens 9117 includes a transmitting collimating lens 9117a and a receiving coupling lens 9117b. The transmitting collimating lens 9117a is arranged corresponding to the light transmitting chip 3031 and the transmitting reflecting surface 9115a, and the receiving coupling lens 9117b is arranged corresponding to the light receiving chip 3032 and the receiving reflecting surface 9115b.

[0154] FIG18 is a first optical path diagram of a first optical transceiver component provided in an embodiment of the present disclosure. FIG19 is a second optical path diagram of a second optical transceiver component provided in an embodiment of the present disclosure. As shown in FIG18 , in some embodiments, the angle between the transmitting reflective surface 9115a and the horizontal plane is the same as the angle between the receiving reflective surface 9115b and the horizontal plane. The angle between the transmitting reflective surface 9115a and the horizontal plane and the angle between the receiving reflective surface 9115b and the horizontal plane are both 45°. The angle between the surface where the transmitting collimating lens 9117a is located and the horizontal plane and the angle between the surface where the receiving coupling lens 9117b is located and the horizontal plane are both 0°. The transmitting collimating lens 9117a and the receiving coupling lens 9117b are arranged side by side along the width direction of the first lens assembly 911, and the optical transmitting chip 3031 and the optical receiving chip 3032 are arranged side by side along the width direction of the circuit board 300.

[0155] The optical transmitter chip 3031 emits a divergent light beam upward. The divergent light beam is converted into a collimated light beam by the transmitting collimating lens 9117a. The collimated light beam is then reflected by the transmitting reflective surface 9115a. The reflected collimated light beam is then converted into a convergent light beam by the transmitting coupling lens and coupled to the optical fiber. The optical fiber is then transmitted to the optical receiver chip in the optical module at the other end of the optical fiber. The light beam emitted by the optical transmitter chip at the other end of the optical fiber is transmitted through the optical fiber to the receiving collimating lens. The receiving collimating lens collimates the light beam into a collimated light beam. The collimated light beam is then reflected by the receiving reflective surface 9115b. The reflected collimated light beam is then directed vertically downward, coupled by the receiving coupling lens 9117b, and vertically incident on the optical receiver chip 3032.

[0156] The angle between the emitting reflection surface 9115a and the horizontal plane is the same as the angle between the receiving reflection surface 9115b and the horizontal plane. The emitting light port slot 9111a provided with the emitting reflection surface 9115a and the receiving light port slot 9111b provided with the receiving reflection surface 9115b are connected to form a light port slot 9111, that is, the emitting reflection surface 9115a and the receiving reflection surface 9115b form a reflection surface 9115, which is convenient for processing and more accurate.

[0157] The angle between the receiving reflective surface 9115b and the horizontal plane is 45°. The portion of the light beam perpendicularly incident on the optical receiving chip 3032 returns to the optical fiber along its original path, affecting the performance of the optical transmitting chip at the other end of the optical fiber. To address this issue, as shown in FIG19 , in some embodiments, the angle between the transmitting reflective surface 9115a and the horizontal plane is 45°, and the angle α between the receiving reflective surface 9115b and the horizontal plane is less than 45°. For example, the angle α between the receiving reflective surface 9115b and the horizontal plane is 30° to 38°, and the angle α between the receiving reflective surface 9115b and the horizontal plane is 39° to 42°.

[0158] The angle between the transmitting reflective surface 9115a and the horizontal plane is 45°, the angle between the surface on which the transmitting collimating lens 9117a is located and the horizontal plane is 0°, the angle between the receiving reflective surface 9115b and the horizontal plane is less than 45°, and the surface on which the receiving coupling lens 9117b is located is moved backward relative to the surface on which the transmitting collimating lens 9117a is located and is tilted, i.e., the angle between the surface on which the receiving coupling lens 9117b is located and the horizontal plane changes from 0° to β. The transmitting collimating lens 9117a and the receiving coupling lens 9117b are staggered along the width direction of the first lens assembly 911. According to the reflection theorem, the angle deflection angle γ between the receiving reflective surface 9115b and the horizontal plane is 45°-α, and the angle deflection angle β between the surface on which the receiving reflective surface 9115b is located and the horizontal plane is 2γ, i.e., the angle β between the surface on which the receiving coupling lens 9117b is located and the horizontal plane is equal to 2*(45°-α).

[0159] The emitting collimating lens 9117a and the receiving coupling lens 9117b are staggered along the width direction of the first lens assembly 911, so the light emitting chip 3031 and the light receiving chip 3032 are staggered along the width direction of the circuit board 300, and the horizontal vertical distance between the light emitting chip 3031 and the light receiving chip 3032 is L = H*tanβ, where H is the vertical distance between the reflecting surface 9115 and the optical chip 303.

[0160] The optical transmitter chip 3031 emits a divergent beam upward. The divergent beam is converted into a collimated beam by the transmitting collimating lens 9117a. The collimated beam is then reflected by the transmitting reflective surface 9115a. The reflected collimated beam is then converted into a convergent beam by the transmitting coupling lens and coupled to the optical fiber. The optical fiber is then transmitted to the optical receiver chip in the optical module at the other end of the optical fiber. The beam emitted by the optical transmitter chip at the other end of the optical fiber is transmitted through the optical fiber to the receiving collimating lens. The receiving collimating lens collimates the beam into a collimated beam. The collimated beam is then reflected by the receiving reflective surface 9115b. The reflected collimated beam is tilted downward and, after being coupled by the receiving coupling lens 9117b, is incident obliquely on the optical receiver chip 3032. The beam incident obliquely on the optical receiver chip 3032 is reflected by the optical receiver chip 3032. Instead of returning along its original path, the reflected beam is tilted upward, thus preventing the beam returning to the optical fiber 9127 from affecting the performance of the optical transmitter chip at the other end of the optical fiber 9127.

[0161] The angle between the emitting reflection surface 9115a and the horizontal plane is different from the angle between the receiving reflection surface 9115b and the horizontal plane. The emitting light port slot 9111a provided with the emitting reflection surface 9115a and the receiving light port slot 9111b provided with the receiving reflection surface 9115b are connected to form a light port slot 9111, that is, the emitting reflection surface 9115a and the receiving reflection surface 9115b form two reflection surfaces with different angles, which is convenient for processing.

[0162] The angle between the emitting reflection surface 9115a and the horizontal plane is different from the angle between the receiving reflection surface 9115b and the horizontal plane. The emitting light port slot 9111a provided with the emitting reflection surface 9115a and the receiving light port slot 9111b provided with the receiving reflection surface 9115b are not connected, that is, the emitting reflection surface 9115a and the receiving reflection surface 9115b are also not connected. The light port slot 9111 is narrowed to ensure that the second sealing glue cannot flow onto the reflection surface 9115.

[0163] In some embodiments, the first seal, the second seal, and the blocking assembly are used to isolate the coolant to prevent the coolant from contaminating the optoelectronic devices in the first lens assembly; the first end face of the optical fiber holder is buried in the package cavity and the blocking protrusion is used to isolate the sealing glue to prevent the sealing glue from contaminating the optical path between the first lens assembly and the optical fiber holder, thereby ensuring the normal operation of the optical module. In some embodiments, the first seal, the second seal, the blocking piece, and a twelfth seal are provided in the first air vent to isolate the coolant to prevent the coolant from contaminating the optoelectronic devices in the first lens assembly; the first end face of the optical fiber holder is buried in the package cavity to isolate the sealing glue to prevent the sealing glue from contaminating the optical path between the first lens assembly and the optical fiber holder, thereby ensuring the normal operation of the optical module; the second seal extends within the gap between the top surface of the optical fiber holder and the package cavity without exceeding the first air vent to facilitate the release of air in the package cavity.

[0164] FIG20 is a structural diagram of a second optical transceiver component provided in an embodiment of the present disclosure. FIG21 is an exploded view of the second optical transceiver component provided in an embodiment of the present disclosure. FIG22 is a cross-sectional view of the second optical transceiver component provided in an embodiment of the present disclosure. As shown in FIG20, FIG21, and FIG22, in some embodiments, the second optical transceiver component 902 includes a second lens assembly 921, an optical fiber holder 922, and a sealing cover plate 923. The sealing cover plate 923 is disposed on the second lens assembly 921. A snap-in groove 9212 is provided at one end of the second lens assembly 921. An optical fiber 9223 is fixed to one end of the optical fiber holder 922. The optical fiber holder 922 carries the optical fiber 9223 and is inserted into the snap-in groove 9212 to achieve connection between the optical fiber holder 922 and the second lens assembly 921. After the optical fiber holder 922 is inserted into the snap-in groove 9212, a second sealing member is disposed between the optical fiber holder 922 and the snap-in groove 9212. The second sealing member is located between each sidewall of the snap-in groove 9212 and each corresponding side surface of the optical fiber holder 922. That is, after inserting the optical fiber holder 922 into the snap-in groove 9212, the first sealing glue is used to seal all the gaps between the side walls of the snap-in groove 9212 and the side surfaces corresponding to the optical fiber holder 922. The first sealing glue is accumulated at the connection between the side walls of the snap-in groove 9212 and the side surfaces corresponding to the optical fiber holder 922. After the first sealing glue is cured, a second sealing member is formed to ensure the connection sealing between the side surfaces of the optical fiber holder 922 except the top surface and the second lens assembly 921, thereby preventing the infiltration of cooling liquid.

[0165] One end of the sealing cover plate 923 covers the optical port slot 9211 of the second lens assembly 921, and the other end of the sealing cover plate 923 covers the optical fiber holder 922 in the engaging slot 9212. The first end face of the optical fiber holder 922 is located on the bottom surface of the sealing cover plate 923. A first sealant is applied to the outer wall of the sealing cover plate 923 to distance the first end face of the optical fiber holder 922 from the location of the first sealant, thereby preventing contamination of the first end face of the optical fiber holder 922 by the first sealant. After the first sealant cures, a fifth sealant is formed. The fifth sealant is located between the outer wall of the sealing cover plate 923, the second lens assembly 921, and the optical fiber holder 922 to isolate them from the coolant. That is, after the sealing cover 923 is covered on the second lens assembly 921 and the optical fiber bracket 922, the first sealing glue is applied to the outer wall of the sealing cover 923 so that the first sealing glue can completely seal the gaps between the sealing cover 923 and the second lens assembly 921 and the optical fiber bracket 922. The first sealing glue is accumulated between the sealing cover 923 and the second lens assembly 921 and the optical fiber bracket 922. After the first sealing glue is cured, a fifth sealing member is formed to ensure the sealing of the connection between the sealing cover 923 and the second lens assembly 921 and the optical fiber bracket 922, thereby preventing the infiltration of cooling liquid.

[0166] As shown in Figure 22, a first lens 9216 is provided in the snap-in groove 9212. The first lens 9216 is provided corresponding to the optical fiber bracket 922. The first lens 9216 includes a receiving collimating lens and an emitting coupling lens. The emitting coupling lens couples the light beam emitted by the second lens assembly 921, and the receiving collimating lens collimates the light beam of the optical fiber 9223 in the optical fiber bracket 922.

[0167] As shown in Figures 21 and 22, an optical port slot 9211 is provided on the second lens assembly 921. The top surface of the optical port slot 9211 (the plane facing away from the circuit board 300) is provided with an opening, and the slot wall of the optical port slot 9211 (the end facing the circuit board 300) forms a reflecting surface 9215. The reflecting surface 9215 is arranged opposite to the first lens 9216. In this way, the optical signal emitted by the optical chip 303 (specifically the optical transmitting chip 3031) is reflected by the reflecting surface 9215, and the reflected light beam is emitted through the first lens 9216. The first lens 9216 reflects the light beam transmitted by the received optical fiber through the reflecting surface 9215, and the reflected light signal is incident on the optical chip 303 (specifically the optical receiving chip 3032).

[0168] The reflecting surface 9215 includes an emitting reflecting surface and a receiving reflecting surface. The emitting reflecting surface is set corresponding to the emitting collimating lens and the light emitting chip, and the receiving reflecting surface is set corresponding to the receiving coupling lens and the light receiving chip 3032. The optical signal emitted by the light emitting chip 3031 is reflected by the emitting reflecting surface, and the reflected optical signal is emitted through the first lens 9216. The first lens 9216 reflects the optical signal transmitted by the optical fiber through the receiving reflecting surface, and the reflected optical signal is incident on the light receiving chip 3032.

[0169] Since an opening is provided on the top surface of the optical port slot 9211 to facilitate demolding of the plastic mold, a sealing cover plate 923 is placed over the optical port slot 9211 to prevent coolant from seeping into the second lens assembly 921 through the opening of the optical port slot 9211. The size of the sealing cover plate 923 corresponding to the optical port slot 9211 is larger than the size of the opening of the optical port slot 9211, so that the sealing cover plate 923 can seal the opening of the optical port slot 9211, thereby reducing the infiltration of coolant into the optical port slot 9211 and ensuring that the optical port slot 9211 is isolated from the coolant.

[0170] In some embodiments, to prevent the first sealant from flowing into the reflective surface 9215, a sealant-isolating protrusion is provided at one end of the wall of the optical port slot 9211. This sealant-isolating protrusion narrows the optical port slot 9211, forming a deep well. Due to the high viscosity of the first sealant, it can only coat the upper portion of the deep well (i.e., the sealant-isolating protrusion of the optical port slot 9211). The air below the deep well supports the first sealant, preventing it from flowing downward onto the reflective surface 9215. This ensures that the reflective surface 9215 is both isolated from the external coolant and unaffected by the first sealant.

[0171] In some embodiments, the sealant protrusions include first sealant protrusions, which are formed by outwardly protruding from the walls of the optical aperture slot 9211. The first sealant protrusions narrow the optical aperture slot 9211, forming a deep well. Due to the viscosity of the first sealant, it can only coat the first sealant protrusions in the upper portion of the deep well. The air below the deep well supports the first sealant, preventing it from flowing downward onto the reflective surface 9215. This ensures that the reflective surface 9215 is both isolated from the external coolant and unaffected by the first sealant.

[0172] In some embodiments, the sealant protrusions further include a second sealant protrusion. The second sealant protrusion is formed by protruding outward from the first groove wall of the first sealant protrusion (referring to the groove wall where the reflective surface is located in the optical port groove 9211). The second sealant protrusion further narrows the optical port groove 9211, forming a deep well groove. Due to the viscosity of the first sealant, it can only cover the first and second sealant protrusions in the upper portion of the deep well groove. The air in the lower portion of the deep well groove supports the first sealant, preventing it from flowing downward onto the reflective surface 9215. This ensures that the reflective surface 9215 is both isolated from the external coolant and unaffected by the first sealant.

[0173] In some embodiments, the second lens assembly 921 is provided with an inclined surface 9213, which slopes along the top surface of the second lens assembly 921 toward the side of the second lens assembly 921 away from the fiber optic bracket 912. In other words, the inclined surface 9213 is a downwardly inclined surface. The rear optical fiber 9223 tilts upward along the inclined surface 9213, giving the optical fiber 9223 a larger bending radius, thereby avoiding fiber transmission problems caused by a fiber radius that is too small.

[0174] As shown in FIG22 , a housing cavity 9222 is provided on the side of the second lens assembly 921 facing the circuit board 300. A second lens 9217 is provided on the inner sidewall of the housing cavity 9222. The second lens 9217 is located below the reflective surface 9215, and the optical chip 303 is located below the second lens 9217. The second lens 9217 can be a transmitting collimating lens, and the optical chip 303 can be a light transmitting chip. In this case, the light beam emitted by the light transmitting chip is converted into a collimated light beam via the transmitting collimating lens. The collimated light beam is then reflected by the reflective surface 9215. The reflected collimated light beam is then converted into a convergent light beam via the first lens 9216 and coupled to the optical fiber. The second lens can also be a receiving coupling lens, and the optical chip 303 can be a light receiving chip. In this case, the received light beam is emitted by the first lens 9216 onto the reflective surface 9215. The received light beam is then reflected by the reflective surface 9215 and coupled to the light receiving chip via the receiving coupling lens.

[0175] In some embodiments, the sealing cover plate 923 and the snap-in groove 9212 form a wrapping cavity. A first air vent is provided on the sealing cover plate 923. The expanded air in the wrapping cavity is released through the first air vent. The first air vent is filled with a second sealing glue. The second sealing glue solidifies to form a twelfth seal. The twelfth seal is used to block the first air vent to prevent the coolant from penetrating into the wrapping cavity through the first air vent.

[0176] In some embodiments, a second air vent is further provided on the second lens assembly 921. The second air vent 9219 is located above the cover cavity 9222. The second air vent 9219 is communicated with the cover cavity 9222. The expanded air in the cover cavity 9222 is released through the air vent 9219 to prevent the coolant from seeping in.

[0177] Figure 23 is a structural diagram of the second lens assembly provided in an embodiment of the present disclosure. As shown in Figure 23, in some embodiments, the optical port slot 9211 includes only one optical port slot, in which an emitting reflective surface and a receiving reflective surface are provided, and the emitting reflective surface and the receiving reflective surface are connected.

[0178] In some embodiments, the optical port slot 9211 includes an emitting optical port slot and a receiving optical port slot, the emitting optical port slot is separated from the receiving optical port slot, an emitting spacer protrusion and an emitting reflecting surface are provided in the emitting optical port slot, a receiving spacer protrusion and a receiving reflecting surface are provided in the receiving optical port slot, the reflecting spacer protrusion and the receiving spacer protrusion are not connected, and the emitting reflecting surface and the receiving reflecting surface are not connected.

[0179] Figure 24 is a structural diagram of the second lens assembly provided by an embodiment of the present disclosure from another perspective. As shown in Figure 24, in some embodiments, the snap-in slot 9212 includes a snap-in wall, a first snap-in side wall, a second snap-in side wall, and a third snap-in side wall. The snap-in wall, the first snap-in side wall, the second snap-in side wall, and the third snap-in side wall form a snap-in slot 9212 having two openings (one opening facing upward and one opening facing right). The snap-in wall, the second snap-in side wall, and the third snap-in side wall are respectively connected to the first snap-in side wall. The second snap-in side wall is disposed opposite the third snap-in side wall. The snap-in wall is provided with a first positioning post 9218 and an inwardly recessed first groove 9214. The second lens 9216 is disposed in the first groove.

[0180] In some embodiments, the first clamping side wall, the second clamping side wall and the third clamping side wall are respectively arranged corresponding to the corresponding side surfaces of the optical fiber bracket 912, and the clamping wall is arranged corresponding to the first end surface of the optical fiber bracket 922 to realize the clamping of the optical fiber bracket 922 in the clamping groove 9212.

[0181] The structure of the optical fiber bracket 922 of the second optical transceiver component 902 is the same as that of the optical fiber bracket 912 of the first optical transceiver component 901, and will not be repeated here.

[0182] FIG25 is a structural diagram of a sealing cover plate provided in an embodiment of the present disclosure. FIG26 is a structural diagram of a sealing cover plate provided in an embodiment of the present disclosure from another perspective. As shown in FIG25 and FIG26, in some embodiments, the top surface of the optical fiber holder 922 is higher than the top surface of the second lens assembly 921. The lower surface of the sealing cover plate 923 is provided with an inwardly recessed covering groove 9232. Each surface of the covering groove 9232 is respectively connected to each corresponding side surface of the optical fiber holder 922. The depth of the covering groove 9232 is greater than or equal to the height difference between the top surface of the optical fiber holder 922 and the top surface of the second lens assembly 921. The depth of the covering groove 9232 is equal to the height difference between the top surface of the optical fiber holder 922 and the top surface of the second lens assembly 921, so that the sealing cover plate 923 is tightly fitted with the second lens assembly 921 and the optical fiber holder 922, thereby improving the sealing performance of the connection between the sealing cover plate 923, the second lens assembly 921 and the optical fiber holder 922.

[0183] In some embodiments, the top surface of the optical fiber bracket 922 is flush with the top surface of the second lens assembly 921, and the lower surface of the sealing cover plate 923 does not need to be provided with an inwardly recessed covering groove 9232, that is, all points on the lower surface of the sealing cover plate 923 are flush.

[0184] In some embodiments, the covering groove 9232 includes a top wall, a first side wall, a second side wall and a third side wall, the first side wall, the second side wall and the third side wall are respectively connected to the top wall, the top wall is connected to the top surface of the optical fiber bracket 922 (the side of the optical fiber bracket 922 away from the circuit board 300), the first side wall and the third side wall are respectively connected to the side surfaces of the optical fiber bracket 922, and the second side wall is connected to the first end surface of the optical fiber bracket 922.

[0185] In some embodiments, the sealing cover plate 923 is made of plastic and is formed by injection molding. There is no covering protrusion on the upper surface of the sealing cover plate 923 , that is, all positions on the upper surface of the sealing cover plate 923 are flush.

[0186] In some embodiments, the sealing cover plate 923 is made of steel plate and is formed by stamping. A covering protrusion 9231 is provided on the upper surface of the sealing cover plate 923 , and the covering protrusion 9231 is corresponding to the covering groove 9232 .

[0187] In the present application, the first seal, the second seal, the sealing cover plate and the fifth seal are used to isolate the coolant to prevent the coolant from contaminating the optoelectronic devices in the second lens assembly; the first end face of the optical fiber holder is located on the bottom surface of the sealing cover plate to isolate the sealing glue to prevent the sealing glue from contaminating the optical path between the second lens assembly and the optical fiber holder, thereby ensuring the normal operation of the optical module.

[0188] FIG27 is a structural diagram of a third optical transceiver component provided in an embodiment of the present disclosure. FIG28 is an exploded view of the third optical transceiver component provided in an embodiment of the present disclosure. FIG29 is a cross-sectional view of the third optical transceiver component provided in an embodiment of the present disclosure. As shown in FIG27, FIG28, and FIG29, in some embodiments, the third optical transceiver component 903 includes a third lens assembly 931, an optical fiber holder 932, and a baffle 934. The third lens assembly 931 is provided with a recessed optical port 9311. The top surface (the plane facing away from the circuit board 300) of the optical port 9311 is provided with an opening, and the opening of the optical port 9311 is covered by a baffle 934. A snap-fitting slot 9312 is provided at one end of the third lens assembly 931. An optical fiber 9323 is fixed to one end of the optical fiber holder 932. The optical fiber holder 932, carrying the optical fiber 9323, is inserted into the snap-fitting slot 9312 to connect the optical fiber holder 932 to the third lens assembly 931.

[0189] A fourth sealant is applied to the gap between the first end face of the optical fiber holder 932 and the third lens assembly 931. The fourth sealant has a greater viscosity than the first sealant, preventing the fourth sealant from seeping into the first end face of the optical fiber holder 932 and the third lens assembly 931, thereby reducing contamination of the first end face of the optical fiber holder 932 by the first sealant. After the fourth sealant cures, a thirteenth sealant is formed, thereby achieving a sealed connection between the first end face of the optical fiber holder 932 and the third lens assembly 931. Specifically, the fourth sealant, having a higher viscosity, is applied to the engaging wall of the engaging groove 9312. When the optical fiber holder 922 is inserted into the engaging groove 9312, the fourth sealant completely seals the gap between the first end face of the optical fiber holder 932 and the engaging wall of the engaging groove 9312. After the fourth sealant cures, a thirteenth sealant is formed, ensuring a tight connection between the first end face of the optical fiber holder 922 and the third lens assembly 931.

[0190] In some embodiments, the third optical transceiver component 903 also includes a sealing dam 933, which is covered on the circuit board 300 and the third lens assembly 931. The first end of the sealing dam 933 is fixed on the circuit board 300, and the second end of the sealing dam 933 is fixed on the third lens assembly 931. The sealing dam 933, the circuit board 300 and the third lens assembly 931 form a storage cavity, and a baffle 934, an optical fiber bracket 932 and a sixth seal are provided in the storage cavity. The sixth seal surrounds the baffle 934 and the optical fiber bracket 932 to seal the gaps between the optical fiber bracket and the baffle and the third lens assembly respectively, thereby ensuring the sealing of the connection between the baffle 934 and the optical fiber bracket 922 and the third lens assembly 931 respectively, thereby preventing the infiltration of cooling liquid.

[0191] Insert the optical fiber holder 922 into the snap-in slot 9312, cover the baffle 934 on the optical port slot 9311, and after the sealing dam 933 is covered on the circuit board 300 and the third lens assembly 931, fill the storage cavity with a third sealing glue with a lower viscosity. The third sealing glue in the storage cavity surrounds the baffle 934 and the optical fiber holder 932 to completely seal the gaps between the optical fiber holder 922 and the baffle 934 and the third lens assembly 931 respectively. After the third sealing glue is cured, a sixth sealing member is formed to ensure the sealing of the connection between the baffle 934 and the optical fiber holder 922 and the third lens assembly 931 respectively, thereby preventing the infiltration of coolant.

[0192] The thirteenth seal is used to block the infiltration of the sixth seal, and the thirteenth seal blocks the gap between the first end face of the optical fiber bracket 932 and the clamping wall of the clamping groove 9312 to prevent the third sealing glue from penetrating into the first end face of the optical fiber bracket 932 and contaminating the optical path between the optical fiber bracket 932 and the third lens assembly 931.

[0193] The third lens assembly 931 of the third optical transceiver component 903 has the same structure as the second lens assembly 921 of the second optical transceiver component 902 , and will not be described in detail here.

[0194] The optical path diagram of the third optical transceiver component 903 is the same as the optical path diagram of the second optical transceiver component 902, and will not be repeated here.

[0195] The optical fiber bracket 932 of the third optical transceiver component 903 has the same structure as the optical fiber bracket 922 of the second optical transceiver component 902 and the optical fiber bracket 912 of the first optical transceiver component 901 , and will not be described in detail here.

[0196] However, the seal that flows into the optical port groove in the third lens assembly 931 is the sixth seal, and the rubber spacer protrusion in the optical port groove supports the sixth seal so that the sixth seal cannot flow into the reflective surface in the optical port groove.

[0197] Figure 30 is a structural diagram of a sealing dam provided in an embodiment of the present disclosure. Figure 31 is a structural diagram of a sealing dam provided in an embodiment of the present disclosure from another perspective. As shown in Figures 30 and 31, in some embodiments, the third lens assembly 931 is disposed over the circuit board 300. The height of the third lens assembly 931 is greater than the height of the circuit board 300, and the thickness of the first end of the sealing dam 933 is greater than the thickness of the second end of the sealing dam 933, so that one end of the sealing dam 933 is fixed to the circuit board 300 and the other end of the sealing dam 933 is fixed to the third lens assembly 931. The thickness refers to the distance between the upper surface and the lower surface of the structure.

[0198] In some embodiments, the sealing dam 933 is a container without an upper cover, so that the third sealing glue can be injected into the sealing dam 933; the sealing dam 933 is a blocking member without a lower cover, so that the third sealing glue in the sealing dam 933 can penetrate into the gap between the optical fiber bracket 932 and the blocking piece 934 and the third lens assembly 931.

[0199] The sealing dam 933 is a hollow enclosure member without upper and lower covers. The sealing dam 933, the circuit board 300 and the third lens assembly 931 form a storage cavity. The circuit board 300 and the third lens assembly 931 serve as the bottom surface of the storage cavity, and the sealing dam 933 serves as the side wall of the storage cavity. An optical fiber bracket 932, a baffle 934 and a sixth sealing member are provided in the storage cavity.

[0200] In some embodiments, the sealing dam 933 is fixed to the circuit board 300 by glue.

[0201] In addition to the above-mentioned method of detachably connecting the sealing dam 933 to the third lens assembly 931 and the circuit board 300, in other examples, the sealing dam 933 can be integrally formed with the third lens assembly 931. Of course, in order to facilitate the docking of the optical fiber holder 932 with the third lens assembly 931, an avoidance channel can be opened on the side of the sealing dam 933 close to the optical fiber holder 932. When the optical fiber holder 932 and the third lens assembly 931 are docked, the avoidance channel is blocked by a shielding member so that the sealing dam encloses a storage cavity between the circuit board 300 and the third lens assembly 931, thereby injecting the third sealing glue into the storage cavity to achieve sealing between the circuit board 300, the third lens assembly 931 and the optical fiber holder 932.

[0202] In some embodiments, the sealing dam 933 is secured to the circuit board 300 via a second positioning post 9335. The second positioning post 9335 is provided at the bottom of one end of the sealing dam 933. The circuit board 300 is provided with a second positioning hole corresponding to the second positioning post 9335. The second positioning post 9335 is inserted into the second positioning hole of the circuit board 300 to secure the sealing dam 933 to the circuit board 300. The provision of the second positioning post 9335 on the sealing dam 933 not only facilitates the installation and positioning of the sealing dam 933, but also facilitates securing the sealing dam 933 to the circuit board 300.

[0203] In some embodiments, the sealing dam 933 is provided with a second positioning column 9335, and a second positioning column 9335 is provided corresponding to a second positioning hole on the circuit board 300. A second positioning column 9335 is inserted into a second positioning hole of the circuit board 300 to fix the sealing dam 933 on the circuit board 300.

[0204] In some embodiments, the sealing dam 933 is provided with two second positioning columns 9335, and the two second positioning columns 9335 are respectively located on both sides of the bottom of one end of the sealing dam 933. The two second positioning columns 9335 are respectively arranged corresponding to the two second positioning holes on the circuit board 300. The two second positioning columns 9335 are respectively inserted into the corresponding second positioning holes of the circuit board 300 to make the sealing dam 933 more stably fixed on the circuit board 300.

[0205] In addition to the second positioning columns 9335 , the bottom of the first end of the sealing dam 933 is also provided with an avoidance hole 9339 . The avoidance hole 9339 is located between the two second positioning columns 9335 . The optical fiber 9323 is placed in the avoidance hole 9339 . The avoidance hole 9339 is used to avoid the optical fiber 9323 .

[0206] In some embodiments, a fourteenth sealing member is further disposed within the avoidance hole 9339. The fourteenth sealing member is used to seal the area of ​​the avoidance hole 9339 excluding the optical fiber 9323. That is, the fourteenth sealing member is disposed within the area between the avoidance hole 9339 and the optical fiber 9323 therein to prevent the third sealing adhesive of lower viscosity within the storage cavity from flowing out through the avoidance hole 9339. Specifically, after the sealing dam 933 is disposed over the circuit board 300 and the third lens assembly 931, the optical fiber 323 is placed within the avoidance hole 9339, and the fourth sealing adhesive of higher viscosity is injected into the avoidance hole 9339. After the fourth sealing adhesive cures, the fourth sealing adhesive of lower viscosity is injected into the storage cavity. The fourth sealing adhesive cures to form the sixth sealing member.

[0207] In some embodiments, the number of avoidance holes 9339 is greater than or equal to the number of optical fibers in the optical fiber holder, so that the sealing dam 933 can avoid the optical fibers in the optical fiber holder. For example, if the optical fiber holder has only one optical fiber, the sealing dam 933 has at least one avoidance hole 9339; if the optical fiber holder has only two optical fibers, the sealing dam 933 has at least two avoidance holes 9339; and if the optical fiber holder has only three optical fibers, the sealing dam 933 has at least three avoidance holes 9339.

[0208] A first snap-in interface 9336 is provided at the bottom of the second end of the sealing dam 933. The first snap-in interface 9336 snaps onto the third lens assembly 931. A snap-in surface 9337 is provided at each end of the first snap-in interface 9336. These snap-in surfaces 9337 correspond to the first seal at the end of the third lens assembly 931. The inclination angle of these snap-in surfaces 9337 is the same as that of the first seal at the end of the third lens assembly 931. This ensures close contact between the snap-in surface 9337 and the first seal at the end of the third lens assembly 931, thereby ensuring a tight connection between the sealing dam 933 and the end of the third lens assembly 931.

[0209] In some embodiments, a second card interface 9338 recessed inwardly is provided on one side of the first card interface 9336, and the second card interface 9338 is snapped onto the upper surface of the third lens assembly 931 and the outer wall of the third lens assembly 931, which not only ensures the stability of the connection between the sealing dam 933 and the third lens assembly 931 and prevents the sealing dam 933 from detaching from the third lens assembly 931, but also ensures the sealing of the connection between the sealing dam 933 and the top of the third lens assembly 931 and prevents the third sealing glue from flowing out along the outer wall of the third lens assembly 931.

[0210] The sealing dam 933 includes a first dam side plate 9331, a second dam side plate 9332, a third dam side plate 9333 and a fourth dam side plate 9334. The first dam side plate 9331, the second dam side plate 9332, the third dam side plate 9333 and the fourth dam side plate 9334 are connected in sequence. The first dam side plate 9331, the second dam side plate 9332, the third dam side plate 9333 and the fourth dam side plate 9334 form a barrier member without an upper or lower cover. The first dam side plate 9331 and the third dam side plate 93 33 are arranged relative to each other, the second dam side plate 9332 and the fourth dam side plate 9334 are arranged relative to each other, a second positioning column 9335 is provided at the bottom of the first dam side plate 9331, a first card interface 9336 and a second card interface 9338 are provided at the bottom of the second dam side plate 9332, the third dam side plate 9333 and the fourth dam side plate 9334, the first card interface 9336 and the second card interface 9338 are both U-shaped, and a card connection surface 9337 is provided at the bottom of the second dam side plate 9332 and the fourth dam side plate 9334.

[0211] In some embodiments, the second positioning column 9335 is inserted into the second positioning hole of the circuit board 300, and the bottom of the first dam side plate 9331 is in contact and connected with the surface of the circuit board 300 to realize the connection between the sealed dam 933 and the circuit board 300; the bottom of the second dam side plate 9332, the third dam side plate 9333 and the fourth dam side plate 9334 are in contact and connected with the third lens assembly 931 to realize the connection between the sealed dam 933 and the third lens assembly 931.

[0212] In some embodiments, the top surface height of the sealing dam is greater than or equal to the top surface height of the optical fiber bracket 932, the top surface height of the optical fiber bracket 932 is greater than or equal to the top surface height of the baffle 934 on the third lens assembly 931, and the top surface height of the sixth seal is greater than or equal to the top surface height of the optical fiber bracket 932, so that the sixth seal blocks the gaps between the optical fiber bracket 932 and the baffle 934 and the third lens assembly 931, respectively, thereby ensuring the sealing of the connection between the optical fiber bracket 932 and the baffle 934 and the third lens assembly 931, respectively.

[0213] In the present application, the first sealing member, the sealing dam and the sixth sealing member are used to isolate the coolant to prevent the coolant from contaminating the optoelectronic devices in the third lens assembly, thereby ensuring the normal operation of the optical module.

[0214] The optical fiber 9127 of the first optical transceiver component 901 , the optical fiber 9223 of the second optical transceiver component 902 , and the optical fiber 9323 of the third optical transceiver component 903 are all optical fibers 101 .

[0215] In some embodiments, the optical module 200 is detachably connected to the optical fiber 101. That is, the optical module 200 has a pluggable optical port, and the optical fiber 101 is connected or disconnected to the optical module 200 by inserting or removing the pluggable optical port. When the optical module is immersed in coolant, the coolant can easily enter the optical module through the pluggable optical port, thereby contaminating the optical module and affecting light transmission.

[0216] Figure 32 is an assembly diagram of an optical module and an optical cable provided in an embodiment of the present disclosure. Figure 33 is an exploded view of an optical module and an optical cable provided in an embodiment of the present disclosure. As shown in Figures 32 and 33, in order to prevent coolant from entering the optical module through the optical port, in some embodiments, the optical module 200 is fixedly connected to the optical fiber 101, and the optical fiber is an active optical fiber or a pigtail. Multiple optical fibers are combined into an optical cable 108, and then the optical module 200 is fixedly connected to the optical cable 108, and the optical cable 108 is an active optical cable (AOC cable) or a pigtail cable (Pigtail cable).

[0217] FIG34 is an exploded view of an optical cable provided in an embodiment of the present disclosure. FIG35 is an exploded view of an optical cable fixture and an optical cable body provided in an embodiment of the present disclosure. FIG36 is a cross-sectional view of an optical cable fixture and an optical cable body provided in an embodiment of the present disclosure. As shown in FIG34, FIG35, and FIG36, in some embodiments, the optical cable 108 includes an optical cable body 182. The optical cable body 182 located within the optical module 200 includes an optical fiber. The optical cable body 182 located outside the optical module 200 includes a cable sheath 1821. The cable sheath 1821 contains an optical fiber 1822 (i.e., the optical fiber 101) and a reinforcing wire 1823. The optical fiber located within the optical module 200 and the optical fiber 1822 located outside the optical module 200 are the same optical fiber. The reinforcing wire 1823 is Kevlar, which has excellent flexibility to protect the optical fiber 1822.

[0218] In some embodiments, the optical cable 108 also includes an optical cable fixing 181, which is covered on one end of the outer side of the optical cable body 182. The optical cable fixing 181 is engaged with the optical module 200. The optical cable fixing 181 is used to fix the optical cable fixing 181 in the outer shell of the optical module 200 and prevent the cooling liquid inside the optical module 200 from seeping into the interior of the optical cable body 182.

[0219] In some embodiments, the optical cable 108 further includes an isolator 183, which is coated in the middle of the outer side of the optical cable body 182. The isolator 183 is used to isolate the coolant from one end of the optical cable 108, thereby preventing the coolant from seeping from one end of the optical cable body 182 to the other end of the optical cable body 182. The middle of the outer side of the optical cable body 182 is only used to indicate the two ends outside the optical cable body 182, but does not indicate the exact middle of the outer side of the optical cable body 182. In other words, the middle of the outer side of the optical cable body 182 is not the midpoint of the outer side of the optical cable body 182. In other words, the isolator 183 can be located anywhere between the two ends of the optical cable body 182.

[0220] In some embodiments, the optical cable 108 also includes an optical cable fixing member 181 and an isolating member 183. The optical cable fixing member 181 is covered on one end of the outer side of the optical cable body 182. The optical cable fixing member 181 is engaged with the optical module 200. The optical cable fixing member 181 is used to fix the optical cable fixing member 181 in the outer shell of the optical module 200 and prevent the cooling liquid inside the optical module 200 from seeping into the interior of the optical cable body 182. The isolating member 183 is covered on the middle of the outer side of the optical cable body 182. The isolating member 183 is used to isolate the cooling liquid from one end of the optical cable 108.

[0221] Figure 37 is an exploded view of an optical cable fixture provided in an embodiment of the present disclosure. Figure 38 is an assembly view of a clamp, a first crimping ring, and a second crimping ring provided in an embodiment of the present disclosure. Figure 39 is an assembly view of the clamp and the first crimping ring provided in an embodiment of the present disclosure. As shown in Figures 37, 38, and 39, in some embodiments, an optical cable fixture 181 includes a clamp 1811. One end of the clamp 1811 engages with the optical port of the optical module 200, and the other end of the clamp 1811 is positioned adjacent to the cable sheath 1821. The clamp 1811 defines a first cavity within which an optical fiber 1822 and a fifth sealant are positioned. After the fifth sealant cures, a seventh sealant is formed. The seventh sealant fills the gap between the inner sidewall of the clamp 1811 and the optical fiber 1822. The seventh sealant is seamlessly connected to the optical fiber 1822 to prevent coolant within the optical module 200 from seeping into the interior of the optical cable body 182 through the first cavity of the clamp 1811.

[0222] To ensure that the fifth sealant not only seals but also protects the optical cable, in some embodiments, the fifth sealant is a soft glue. For example, the fifth sealant is silicone. Clamp 1811 includes a clamp body 1815 and a stop protrusion 1816. Clamp body 1815 is located at one end of clamp 1811, and stop protrusion 1816 is located at the other end of clamp 1811 (closer to the optical module relative to clamp body 1815). The inner sides of clamp body 1815 and stop protrusion 1816 form a first cavity.

[0223] In some embodiments, the optical cable fixture 181 further includes a second crimping ring 1813. One end of the second crimping ring 1813 is crimped onto the reinforcement wire 1823 on the outside of the clamp 1811, and the other end of the second crimping ring 1813 is crimped onto the cable sheath 1821, thereby compressing the optical cable fixture 181 and the reinforcement wire 1823 to ensure that the required tension of the optical cable 108 is met. When the second crimping ring 1813 is pushed to the stop protrusion 1816 on the outside of the clamp 1811, the end of the reinforcement wire 1823 (Kevlar) passes over the second crimping ring 1813, ensuring that the required tension of the optical cable body 182 is met.

[0224] However, the end of the reinforcing wire 1823 (Kevlar) passes over the second crimping ring 1813, and the coolant will penetrate into the interior of the optical cable body 182 along the reinforcing wire 1823 (Kevlar). In order to prevent the coolant from penetrating into the interior of the optical cable body 182 along the reinforcing wire 1823 (Kevlar), in some embodiments, the optical cable fixing member 181 further includes a first crimping ring 1812 and a second crimping ring 1813. The first crimping ring 1812 is provided on the outside of the clamp body 1815 and is located in front of the stop protrusion 1816. A reinforcing wire 1823 is provided between the first crimping ring 1812 and the outside of the clamp 1811. 3. Crimp the reinforcement wire 1823 onto the outside of the clamp body 1815. One end of the second crimping ring 1813 is crimped onto the right end of the outside of the first crimping ring 1812. The center of the second crimping ring 1813 is crimped onto the reinforcement wire 1823 on the outside of the clamp body 1815. The other end of the second crimping ring 1813 is crimped onto the cable sheath 1821. This compresses the optical cable fixture 181 and the reinforcement wire 1823, thereby ensuring that the required tension of the optical cable 108 is met. Push the first crimping ring 1812 to the stop protrusion 1816 on the outside of the clamp 1811. Wrap the end of the reinforcement wire 1823 (Kevlar) inside the first crimping ring 1812. Crimping the first crimping ring 1812 ensures that the Kevlar is crimped between the clamp 1811 and the first crimping ring 1812. Push the second crimping ring 1813 to the stop protrusion 1816 of the clamp 1811, and crimp the second crimping ring 1813 so that the second crimping ring 1813 is respectively crimped to the first crimping ring 1812, the reinforcement wire 1823 outside the clamp 1811, and the cable sheath 1821, thereby ensuring that the tension of the optical cable 108 meets the requirements.

[0225] In some embodiments, the reinforcing wire 1823 must not extend beyond the left end of the first crimping ring 1812 to prevent coolant from the outside of the optical module from seeping through the reinforcing wire 1823 into the optical fibers 1822 within the optical cable body 182. After crimping the second crimping ring 1813, inspect the second crimping ring 1813 for flatness, any damaged threads, and visibility of the first crimping ring 1812. Once the second crimping ring 1813 is flat, free of damaged threads, and the first crimping ring 1812 is clearly visible, perform a tensile test to ensure the cable reaches a tensile strength of 15 kg / min.

[0226] After completing the tensile test, apply the sixth sealing glue on the outside of the first crimping ring 1812, apply the sixth sealing glue on the gap between the first crimping ring 1812 and the clamp body 1811, apply the sixth sealing glue on the connection between the first crimping ring 1812 and the second crimping ring 1813, and apply the sixth sealing glue on the connection between the second crimping ring 1813 and the optical cable body 182. After the silicone has been stationary for a period of time, the sixth sealing glue on the outside of the first crimping ring 1812, the gap between the first crimping ring 1812 and the clamp body 1811, and the connection between the first crimping ring 1812 and the second crimping ring 1813 solidifies to form an eighth seal, and the sixth sealing glue at the position of the optical cable body 182 solidifies to form a ninth seal. The eighth seal not only seals the gap between first crimping ring 1812 and second crimping ring 1813 to ensure a sealed connection between the first and second crimping rings 1812 and 1813, but also seals the gap between first crimping ring 1812 and clamp body 1811 to ensure a sealed connection between clamp body 1811 and first crimping ring 1812. Furthermore, it isolates first crimping ring 1812 from the coolant to prevent the coolant from seeping into optical fibers 1822 within optical cable body 182 through reinforcement wire 1823. The ninth seal seals the gap between optical cable body 182 and second crimping ring 1813 to ensure a sealed connection between second crimping ring 1813 and optical cable body 182.

[0227] In some embodiments, the sixth sealing glue is a soft glue. For example, the fifth sealing glue is silicone. The optical cable fixture 181 also includes a protective sleeve 1814, which is disposed over the eighth sealing member, the second crimping ring 1813, and the cable sheath 1821 to protect the optical cable body 182. The height of the eighth sealing member must not exceed the height of the second crimping ring 1813 to prevent the protective sleeve 1814 from being pushed to the fixed position of the clamp 1811, that is, before the protective sleeve 1814 is fixed to the stop protrusion 1816 of the clamp 1811. The eighth sealing member evenly covers the first crimping ring 1812, further preventing the reinforcement wire 1823 from being exposed to the coolant. The ninth sealing member evenly covers the gap between the optical cable body 182 and the second crimping ring 1813, further ensuring a sealed connection between the second crimping ring 1813 and the optical cable body 182.

[0228] In some embodiments, the seventh seal is filled in the first cavity of the clamp to prevent the cooling liquid inside the optical module from penetrating into the interior of the optical cable body through the first cavity of the clamp; the reinforcement wire is crimped by the first crimping ring, and the reinforcement wire must not exceed the left end of the first crimping ring to prevent the cooling liquid outside the optical module from penetrating into the optical fiber inside the optical cable body through the reinforcement wire; the second crimping ring crimps the first crimping ring and the reinforcement wire to ensure the tension of the optical cable.

[0229] In some embodiments, the optical cable body 182 located outside the optical module 200 includes a cable sheath 1821, a reinforcing wire 1823, and an optical fiber 1822. A tenth sealing member, optical fiber 1822, and reinforcing wire 1823 are disposed within the cable sheath 1821. The tenth sealing member is coated on the inner wall of the cable sheath 1821, and the tenth sealing member is coated on the optical fiber 1822 and reinforcing wire 1823 to prevent coolant from penetrating from one end of the optical cable body 182 to the other end. Specifically, a seventh sealing adhesive is applied to the inner wall of the cable sheath 1821, the optical fiber 1822, and the reinforcing wire 1823. The seventh sealing adhesive cures to form the tenth sealing member, which is coated on the inner wall of the cable sheath 1821, the optical fiber 1822, and the reinforcing wire 1823 to prevent coolant from penetrating from one end of the optical cable body 182 to the other end.

[0230] In some embodiments, the optical cable body 182 located outside the optical module 200 is an uncut optical cable body, which includes a first optical cable body. The first optical cable body includes an unbroken cable sheath 1821, an unbroken reinforcement wire 1823 and an unbroken optical fiber 1822. The inner wall of the unbroken cable sheath 1821, the unbroken optical fiber 1822 and the unbroken reinforcement wire are all coated with a seventh sealing glue. The seventh sealing glue is cured to form a tenth sealing member. The tenth sealing member is coated on the inner wall of the cable sheath 1821, the optical fiber 1822 and the reinforcement wire 1823 to prevent the cooling liquid from penetrating from one end of the optical cable body 182 to the other end of the optical cable body 182.

[0231] In some embodiments, the optical cable body 182 located outside the optical module 200 is an uncut optical cable body, and an isolating member 183 is provided on the outside of the uncut optical cable body. The uncut optical cable body includes a first optical cable body, and the first optical cable body includes an unbroken cable sheath 1821, an unbroken reinforcement wire 1823 and an unbroken optical fiber 1822. The inner wall of the unbroken cable sheath 1821, the unbroken optical fiber 1822 and the unbroken reinforcement wire are all coated with a seventh sealing glue, and the seventh sealing glue is cured to form a tenth sealing member, which is coated on the inner wall of the cable sheath 1821, the optical fiber 1822 and the reinforcement wire 1823 to prevent the cooling liquid from penetrating from one end of the optical cable body 182 to the other end of the optical cable body 182.

[0232] In some embodiments, the tenth sealing member fills the gap between the inner wall of the cable sheath 1821 and the unbroken optical fiber 1822 and the unbroken reinforcing wire 1823 , and the tenth sealing member is seamlessly connected to the unbroken optical fiber 1822 and the unbroken reinforcing wire 1823 .

[0233] Figure 40 is an exploded view of the optical cable body and the spacer provided in an embodiment of the present disclosure. Figure 41 is a cross-sectional view of the optical cable body and the spacer provided in an embodiment of the present disclosure. In some embodiments, the optical cable body 182 located outside the optical module 200 is a cut optical cable body, and an isolating member 183 is provided on the outside of the cut optical cable body. The cut optical cable body includes a second optical cable body, which includes a disconnected cable sheath 1821, an undisconnected reinforcing wire 1823, and an undisconnected optical fiber 1822. A seventh sealing glue is applied to the inner wall of the disconnected cable sheath 1821, the outer wall of the disconnected cable sheath 1821, the cross section of the disconnected cable sheath 1821, the outer wall of the undisconnected reinforcing wire 1823, and the outer wall of the undisconnected optical fiber 1822. The seventh sealing glue is cured to form a tenth sealing member, which is coated on the inner wall of the cable sheath 1821, the outer wall of the disconnected cable sheath 1821, the cross section of the disconnected cable sheath 1821, the outer wall of the undisconnected reinforcing wire 1823, and the outer wall of the undisconnected optical fiber 1822 to prevent the cooling liquid from penetrating from one end of the optical cable body 182 to the other end of the optical cable body 182.

[0234] As shown in FIG41 , in some embodiments, the tenth seal fills the gap between the inner wall of the isolation sleeve 1831 and the disconnected cable sheath 1821 , the undisconnected optical fiber 1822 , and the undisconnected reinforcement wire 1823 , and the tenth seal is seamlessly connected to the disconnected cable sheath 1821 , the undisconnected optical fiber 1822 , and the disconnected reinforcement wire 1823 .

[0235] In some embodiments, the optical cable body 182 located outside the optical module 200 is a cut optical cable body, and an isolation piece 183 is provided on the outside of the cut optical cable body. The cut optical cable body includes a third optical cable body, and the third optical cable body includes a disconnected cable sheath 1821, a disconnected reinforcement wire 1823 and an undisconnected optical fiber 1822. The inner wall of the disconnected cable sheath 1821, the outer wall of the disconnected cable sheath 1821, the cross section of the disconnected cable sheath 1821, the outer wall of the disconnected reinforcement wire 1823, the cross section of the disconnected reinforcement wire 1823 and the outer wall of the undisconnected optical fiber 1822 are coated with a seventh sealing glue. After the seventh sealing glue is cured, a tenth sealing member is formed. The tenth sealing member is coated on the inner wall, the outer wall of the disconnected cable sheath, the disconnected surface of the disconnected cable sheath, the outer wall of the disconnected reinforcement wire, the cross section of the disconnected reinforcement wire and the outer wall of the undisconnected optical fiber to prevent the cooling liquid from penetrating from one end of the optical cable body to the other end of the optical cable body.

[0236] In some embodiments, the tenth sealing member fills the gap between the inner wall of the isolation sleeve 1831 and the disconnected cable sheath 1821, the disconnected optical fiber 1822, and the undisconnected reinforcement wire 1823, and the tenth sealing member is seamlessly connected to the disconnected cable sheath 1821, the disconnected optical fiber 1822, and the undisconnected reinforcement wire 1823.

[0237] As shown in Figures 40 and 41, in some embodiments, the isolation member 183 includes an isolation sleeve 1831, a second cavity is provided in the isolation sleeve 1831, a second optical cable body and a tenth sealing member are provided in the second cavity, and the tenth sealing member fills the gap between the second optical cable body and the isolation sleeve 1831 to prevent the cooling liquid from penetrating from one end of the optical cable body 182 to the other end of the optical cable body 182.

[0238] In some embodiments, the isolation member 183 includes an isolation sleeve 1831, a second cavity is provided in the isolation sleeve 1831, a third optical cable body and a tenth sealing member are provided in the second cavity, and the tenth sealing member fills the gap between the third optical cable body and the isolation sleeve 1831 to prevent the cooling liquid from penetrating from one end of the optical cable body 182 to the other end of the optical cable body.

[0239] The length of the broken reinforcement line in the second cavity is 3 to 5 mm to ensure that the tension of the isolation member 183 meets the requirements.

[0240] Isolation sleeve 1831 includes a first inner plug and a second inner plug. The first and second inner plugs are identical in shape and connected to form isolation sleeve 1831, which has a second cavity and two first through-holes 1837. Apply the seventh sealant to the bottom of the first inner plug. Install the cut optical cable body inside the first inner plug. Then apply another layer of the seventh sealant to completely seal the cut ends of the cut optical cable body. Cover with the second inner plug and secure the first and second inner plugs with masking tape. Dry the secured first and second inner plugs at 100°C for at least one hour, allowing the seventh sealant to cure to form the tenth seal.

[0241] In some embodiments, isolation member 183 further includes protective tail tubes 1833 and 1834, which are respectively mounted on both ends of isolation sleeve 1831 to protect the optical cable body. After the seventh sealant within isolation sleeve 1831 cures to form a tenth sealant, protective tail tubes 1833 are placed on both ends of isolation sleeve 1831.

[0242] The protective tail tube 1833 is provided with a third through hole 1839 , which is provided corresponding to the first through hole 1837 to avoid the optical cable body 182 , so that the optical cable body 182 passes through the first through hole 1837 and the third through hole 1839 .

[0243] Both the protective tail tube 1833 and the protective tail tube 1834 include a clamping end and a protective end. One end of the clamping end is covered at both ends of the isolation sleeve 1831, and the other end of the clamping end is connected to one end of the protective end, and the other end of the protective end wraps around the optical cable body 182. One end of the protective end is not parallel to the other end of the protective end, so that the protective end has a certain inclination angle.

[0244] In some embodiments, the inclination angle of the protection end is not equal to 90°, so as to reduce the stress received by the optical cable body 182 and protect the optical cable body 182 .

[0245] In some embodiments, isolation member 183 further includes a heat shrink tubing, which is sleeved over isolation sleeve 1831 to ensure the stability of isolation sleeve 1831. After the seventh sealant in isolation sleeve 1831 cures to form a tenth sealant, the heat shrink tubing is placed over isolation sleeve 1831 and heated by a heater to shrink the tubing and secure it to isolation sleeve 1831, thereby improving the stability of isolation sleeve 1831.

[0246] However, since the isolation sleeve 1831 is composed of a first inner block and a second inner block, there is a gap at the connection between the first inner block and the second inner block, which makes the strength of the isolation sleeve 1831 at the connection between the first inner block and the second inner block poor, and easily causes the isolation sleeve 1831 to break at the connection between the first inner block and the second inner block.

[0247] Figure 42 is an exploded view of an isolator provided in an embodiment of the present disclosure. Figure 43 is a cross-sectional view of an isolator provided in an embodiment of the present disclosure. Figure 44 is a cross-sectional view of a protective sleeve and a protective tail tube provided in an embodiment of the present disclosure. As shown in Figures 42, 43, and 44, to prevent the isolation sleeve 1831 from breaking, in some embodiments, the isolator 183 further includes a protective sleeve 1832 and a protective tail tube 1833. The protective sleeve 1832 is mounted on the isolation sleeve 1831 to ensure the strength of the isolation sleeve 1831. The two protective tail tubes 1833 are respectively mounted on both ends of the protective sleeve 1832 to protect the optical cable body 182.

[0248] Second through holes 1838 are provided at both ends of the protective sleeve 1832 , and the second through holes 1838 are correspondingly arranged to the first through hole 1837 and the third through hole 1839 to avoid the optical cable body 1822 , so that the optical cable body 1822 passes through the first through hole 1837 , the second through hole 1838 and the third through hole 1839 .

[0249] Two limiting protrusions 1835 are provided on the outside of the protective sleeve 1832, located at either end of the protective sleeve 1832. The protective sleeve 1832 is connected to the clipping end of the protective tail tube 1833 to define the clipping position of the protective tail tube 1833 within the protective sleeve 1832. A third cavity is provided on the inside of the protective sleeve 1832, within which are disposed the isolation sleeve 1831 and the eleventh sealing member. The eleventh sealing member is located between the isolation sleeve 1831 and the protective sleeve 1832 to fill the gap between the optical cable body 182, the isolation sleeve 1831, and the protective sleeve 1832, thereby achieving a stable connection between the isolation sleeve 1831 and the protective sleeve 1832, and a sealed connection between the protective sleeve 1832 and the optical cable body 182.

[0250] In some embodiments, a limiting step 1836 is provided in the third cavity inside the protective sleeve 1832. The limiting step 1836 is used to limit the position of the isolation sleeve 1831 inside the protective sleeve 1832. For example, a limiting step 1836 is provided at one end of the third cavity inside the protective sleeve 1832, and the isolation sleeve 1831 is located between the other end of the third cavity and the limiting step 1836 to limit the position of the isolation sleeve 1831 within the protective sleeve 1832. For example, a limiting step 1836 is provided at each end of the third cavity inside the protective sleeve 1832, and the isolation sleeve 1831 is located between the two limiting steps 1836 to limit the position of the isolation sleeve 1831 within the protective sleeve 1832.

[0251] In some embodiments, an eleventh seal is provided in the area of ​​the third cavity except for the isolation sleeve 1831. The eleventh seal is located between the limiting step 1836 and the inner side wall of the protective sleeve 1832. It is not only used to achieve a fixed connection between the isolation sleeve 1831 and the protective sleeve 1832, but also used to achieve a sealed connection between the protective sleeve 1832 and the optical cable body 182 to further prevent the infiltration of cooling liquid.

[0252] The protective sleeve 1832 is a hollow cylinder (with a third cavity on the inside). After the seventh sealing glue in the isolation sleeve 1831 solidifies into the tenth sealing component, the seventh sealing glue is applied to the outside of the isolation sleeve 1831 and inserted into the protective sleeve 1832. The seventh sealing glue is applied to both ends of the protective sleeve 1832 and sealed, and then placed at a high temperature of 100°C to dry for more than 1 hour, waiting for the seventh sealing glue to solidify to form the eleventh sealing component. After the seventh sealing glue in the protective sleeve 1832 solidifies into the eleventh sealing component, the protective tail pipe 1833 is respectively put on the two ends of the protective sleeve 1832.

[0253] In some embodiments, the seventh sealant is a hard glue, for example, a hot melt glue. Epoxy-based sealants are also hard glues, but the seventh sealant has a lower hardness than the epoxy-based sealant and a higher hardness than the fifth and sixth sealants.

[0254] In some embodiments, an optical cable is optically connected to an optical module, a coolant is contained within the optical module, and the optical cable includes an optical cable body. The optical cable body located outside the optical module includes a cable sheath, reinforcing wires, and optical fibers. A tenth sealant, optical fibers, and reinforcing wires are disposed within the cable sheath. The tenth sealant covers the inner wall of the cable sheath, and the tenth sealant covers the optical fibers and reinforcing wires, thereby encapsulating the inner wall of the cable sheath, the optical fibers, and the reinforcing wires to prevent the coolant from seeping from one end of the optical cable body to the other end of the optical cable body. In some embodiments, a tenth sealant is disposed within the cable sheath, and the tenth sealant covers the inner wall of the cable sheath, the reinforcing wires, and the optical fibers to prevent the coolant from seeping from one end of the optical cable body to the other end of the optical cable body.
