[0070] In optical communication technology, in order to establish information transmission between information processing devices, it is necessary to load information onto light and use the propagation of light to achieve information transmission. Here, the light loaded with information is an optical signal. When optical signals are transmitted in information transmission equipment, the loss of optical power can be reduced, so high-speed, long-distance, and low-cost information transmission can be achieved. The signals that information processing equipment can recognize and process are electrical signals. Information processing equipment usually includes optical network terminals (Optical Network Unit, ONU), gateways, routers, switches, mobile phones, computers, servers, tablets, televisions, etc., and information transmission equipment usually includes optical fibers and optical waveguides.

[0071] The optical module can realize the mutual conversion between optical signals and electrical signals between information processing equipment and information transmission equipment. For example, at least one of the optical signal input end or the optical signal output end of the optical module is connected to an optical fiber, and at least one of the electrical signal input end or the electrical signal output end of the optical module is connected to an optical network terminal; the first optical signal from the optical fiber is transmitted to the optical module, and the optical module converts the first optical signal into a first electrical signal, and transmits the first electrical signal to the optical network terminal; the second electrical signal from the optical network terminal is transmitted to the optical module, and the optical module converts the second electrical signal into a second optical signal, and transmits the second optical signal to the optical fiber. Since multiple information processing devices can transmit information through electrical signals, at least one of the multiple information processing devices needs to be directly connected to the optical module, and all information processing devices do not need to be directly connected to the optical module. Here, the information processing device directly connected to the optical module is called the upper computer of the optical module. In addition, the optical signal input end or the optical signal output end of the optical module can be called an optical port, and the electrical signal input end or the electrical signal output end of the optical module can be called an electrical port.

[0072] Figure 1 FIG. 1 is a partial architecture diagram of an optical communication system according to some embodiments. Figure 1 As shown, 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 .

[0073] One end of the optical fiber 101 extends toward the remote information processing device 1000, and the other end of the optical fiber 101 is connected to the optical module 200 through the optical port of the optical module 200. The optical signal can be totally reflected in the optical fiber 101, and the propagation of the optical signal in the total reflection direction can almost maintain the original optical power. The optical signal undergoes multiple total reflections in the optical fiber 101 to transmit the optical signal from the remote information processing device 1000 to the optical module 200, or to transmit the optical signal from the optical module 200 to the remote information processing device 1000, thereby realizing long-distance, low-power loss information transmission.

[0074] The optical communication system may include one or more optical fibers 101, and the optical fibers 101 are 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 working state of the optical module 200.

[0075] 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 so that the host computer 100 and the optical module 200 establish a unidirectional or bidirectional electrical signal connection.

[0076] The host computer 100 also includes an external electrical interface, which can be connected to an electrical signal network. For example, the external electrical interface includes a Universal Serial Bus (USB) interface or a network cable interface 104, and the network cable interface 104 is configured to access the 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 as to establish an electrical signal connection between the local information processing device 2000 and the host computer 100 through the network cable 103. For example, the third electrical signal sent by the local information processing device 2000 is transmitted to the host computer 100 through the network cable 103, and the host computer 100 generates a second electrical signal according to the third electrical signal. The second electrical signal from the host computer 100 is transmitted to the optical module 200, and 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, and the second optical signal is transmitted to the remote information processing device 1000 in the optical fiber 101. For example, the first optical signal from the remote information processing device 1000 is transmitted through the optical fiber 101, and the first optical signal from the optical fiber 101 is transmitted to the optical module 200, and the optical module 200 converts the first optical signal into a first electrical signal, and the optical module 200 transmits the first electrical signal to the host computer 100, and the host computer 100 generates a fourth electrical signal according to the first electrical signal, and transmits the fourth electrical signal to the local information processing device 2000. It should be noted that the optical module is a tool for realizing the mutual conversion between optical signals and electrical signals. During the conversion process between the optical signals and electrical signals, the information does not change, but the encoding and decoding methods of the information can change.

[0077] 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.

[0078] Figure 2 FIG. 1 is a partial structural diagram of a host computer according to some embodiments. In order to clearly show the connection relationship between the optical module 200 and the host computer 100, Figure 2 Only the structure of the host computer 100 related to the optical module 200 is shown. Figure 2 As shown, the host computer 100 further includes a PCB circuit board 105 disposed in 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 inside the cage 106. The electrical connector is configured to access the electrical port of the optical module 200; the heat sink 107 has a protruding structure such as fins to increase the heat dissipation area.

[0079] The optical module 200 is inserted into the cage 106 of the host computer 100, and the cage 106 fixes the optical module 200. The heat generated by the optical module 200 is transferred to the cage 106 and then diffused through the heat sink 107. After the optical module 200 is inserted into the cage 106, the electrical port of the optical module 200 is connected to the electrical connector inside the cage 106, so that the optical module 200 establishes a bidirectional electrical signal connection with the host computer 100. In addition, the optical port of the optical module 200 is connected to the optical fiber 101, so that the optical module 200 establishes a bidirectional optical signal connection with the optical fiber 101.

[0080] Figure 3 A structural diagram of an optical module provided according to some embodiments. Figure 4 FIG. 1 is an exploded view of an optical module provided according to some embodiments. Figure 3 and Figure 4 As shown, the optical module 200 includes a shell, a circuit board 300 disposed in the shell, and an optical transceiver component 900 .

[0081] The housing comprises 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 body.

[0082] In some embodiments, the lower shell 202 includes a bottom plate 2021 and two lower side plates 2022 located on both sides of the bottom plate 2021 and arranged perpendicular to the bottom 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.

[0083] In some embodiments, the lower shell 202 includes a bottom plate 2021 and two lower side plates 2022 located on both sides of the bottom plate 2021 and vertically arranged with the bottom 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 vertically arranged with the cover plate 2011, and the two upper side plates are combined with the two lower side plates 2022 to realize that the upper shell 201 covers the lower shell 202.

[0084] The direction of the line connecting the two openings 204 and 205 may be consistent with the length direction of the optical module 200, or may be inconsistent with the length direction of the optical module 200. For example, the opening 204 is located at the end of the optical module 200 ( Figure 3 The opening 205 is also located at the end of the optical module 200 ( Figure 3Alternatively, the opening 204 is located at the end of the optical module 200, and the opening 205 is located at the side of the optical module 200. The opening 204 is an electrical port, and the gold finger of the circuit board 300 extends from the electrical port and is inserted into the electrical connector of the host computer 100; the opening 205 is an optical port, which is configured to access the external optical fiber 101 so that the optical fiber 101 is connected to the optical transceiver component 900 in the optical module 200.

[0085] The upper housing 201 and the lower housing 202 are combined to facilitate the installation of the circuit board 300 and the optical transceiver component 900 into the housing, and the upper housing 201 and the lower housing 202 can encapsulate and protect the components. In addition, when assembling the circuit board 300 and the optical transceiver component 900, the positioning components, heat dissipation components, and electromagnetic shielding components of these components are conveniently arranged, which is conducive to automated production.

[0086] In some embodiments, the upper shell 201 and the lower shell 202 are made of metal materials to facilitate electromagnetic shielding and heat dissipation.

[0087] 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.

[0088] For example, the unlocking component 600 is located on the outside of the two lower side plates 2022 of the lower housing 202, and includes a snap-fit ​​component that matches 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 fixes 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 relationship between the snap-fit ​​component and the host computer, so as to release the fixation of the optical module 200 and the host computer, so that the optical module 200 can be pulled out of the cage 106.

[0089] The circuit board 300 includes circuit traces, electronic components and chips, etc. The electronic components and chips are connected according to the circuit design through the circuit traces to realize the functions of power supply, electrical signal transmission and grounding.

[0090] 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.

[0091] The circuit board 300 also includes a gold finger formed on the end surface thereof, 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 provided on the surface of only one side of the circuit board 300 (for example, Figure 4 The upper surface shown in the figure) can also be set on the upper and lower surfaces of the circuit board 300 to provide a larger number of pins, so as to adapt to occasions where the number of pins is large. 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.

[0092] In some embodiments, the optical transceiver component 900 includes only a first optical transceiver component or 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 a group of light transmission and a group of light reception.

[0093] In some embodiments, the optical transceiver component 900 includes two first optical transceiver components or 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 achieve two groups of light transmission and two groups of light reception.

[0094] In some 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.

[0095] Figure 5 A cross-sectional view of an optical transceiver component and a circuit board according to some embodiments. Figure 6 FIG. 1 is an exploded view of an optical transceiver component and a circuit board according to some embodiments. Figure 5 and Figure 6 As shown, the circuit board 300 is provided with an optical matching chip 302 and an optical chip 303. 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 by silver glue to play a role of fixing and heat dissipation. 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 on the circuit board 300 side by side.

[0096] In some embodiments, the optical transceiver component 900 includes an optical fiber bracket and a lens assembly, the optical fiber bracket 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.

[0097] 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 transmitting chip is perpendicular to the circuit board 300, and the light beam received by the optical receiving chip 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 it is necessary to change the transmission direction of the light beam emitted by the optical transmitting chip and the external light beam transmitted to the optical receiving chip. Therefore, the light beam emitted by the optical transmitting chip is changed through the lens component, so that the light beam emitted by the optical transmitting chip 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 be convenient for being received by the optical receiving chip.

[0098] like Figure 6 As shown, a DSP chip 301 is also provided on the circuit board 300, and the DSP chip 301 is used for processing high-frequency signals. The high-frequency signal received by the optical receiving chip 3032 at the receiving end is amplified by the TIA chip 3022, and then transmitted to the DSP chip 301 for processing via the high-frequency signal line connecting the TIA chip 3022 and the DSP chip 301, and then transmitted to the communication system via the gold finger. The transmitting end is just the opposite. After the signal is received at the gold finger, it is processed by the DSP chip 301. The processed signal is transmitted to the laser driving chip 3021 via the signal line connecting the DSP chip 301 and the laser driving chip 3021, and then transmitted to the optical transmitting chip 3031 to be converted into an optical signal. The optical signal emitted by the optical transmitting chip 3031 is coupled into the optical fiber through the lens assembly of the optical transceiver component 900 for transmission.

[0099] With the increase of communication rate, although the power consumption per unit bandwidth is decreasing, the overall power consumption of optical modules is still increasing. The heat dissipation method used in client devices is mostly air cooling. For high-speed transmission systems, its heat dissipation capacity has reached its limit. In order to get rid of the dilemma of air cooling, people began to study various liquid cooling methods. One of the liquid cooling methods is to immerse the switch in a refrigerant such as fluorinated liquid (FC-40). However, due to the requirement of low cost, the optical modules deployed in data centers mostly use non-sealed design structures for their optical transmitting components and optical receiving components, and their key optical paths are all in an open state. When the optical module enters the refrigerant with the switch, these key optical paths and components will also enter the refrigerant, causing changes in the optical mechanism and contamination of the optical surface, seriously affecting the normal operation of the optical module.

[0100] In some embodiments, in order to prevent the coolant from penetrating into the optical chip 303 and the optical matching chip 302 inside the lens assembly through the gap between the lens assembly and the circuit board 300, after the lens assembly cover is set on the optical chip 303 and the optical matching chip 302, a first sealant is provided between the lens assembly and the circuit board 300. The first sealant is located on the outer wall of the lens assembly and the surface of the circuit board 300, that is, the sealant is added 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 is accumulated on the surface of the circuit board 300 and the outer wall of the lens assembly, so that the first sealant is formed after the sealant is cured. For example, the lens assembly can be a first lens assembly, and a first sealant is provided between the first lens assembly and the circuit board 300; the lens assembly can be a second lens assembly, and a first sealant is provided between the second lens assembly and the circuit board 300; the lens assembly can be a third lens assembly, and a first sealant is provided between the third lens assembly and the circuit board 300.

[0101] In some embodiments, the sealing glue is an epoxy system glue, which has excellent chemical corrosion resistance, heat resistance and bonding properties, and can better prevent the coolant from penetrating.

[0102] 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, and the viscosity of the third sealing glue is less than the viscosity of the fourth sealing glue.

[0103] In some embodiments, in order to prevent 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.

[0104] 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 arranged corresponding to the side surfaces corresponding to the optical fiber holder, and the snap-in surface of the snap-in groove is arranged corresponding to the first end surface of the optical fiber holder. After the optical fiber holder is placed in the snap-in groove, the first sealing glue is injected into the gap between the snap-in groove and the optical fiber holder (including the gap between the three side surfaces of the snap-in groove and the side surface 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), and a sealing member is formed after the first sealing glue is cured to prevent the coolant from penetrating through the gap between the optical fiber holder and the snap-in groove.

[0105] However, when the first sealing glue is injected into the gap between the clamping surface of the clamping groove and the first end surface 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 surface 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.

[0106] In order to solve this problem, a covering member is provided to cover the gap between the lens assembly and the first end of the optical fiber bracket. The first sealing glue is applied on the outer wall of the covering 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 not easily contaminated by the first sealing glue.

[0107] In some embodiments, the shielding member is integrally formed with other structures of the lens assembly, the shielding member and the snap-in groove form a wrapping cavity, and the shielding member is a side wall of the wrapping cavity away from the circuit board.

[0108] In some 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 covers the optical fiber bracket and the other end of which covers the optical port groove.

[0109] Figure 7 It is a structural diagram of a first optical transceiver component provided according to some embodiments. Figure 8 An exploded view of a first optical transceiver component provided according to some embodiments. Fig. 9 FIG. 4 is a cross-sectional view of a first optical transceiver component provided according to some embodiments. Figure 7 , Figure 8 and Fig. 9 As shown, in some embodiments, the first optical transceiver component 901 includes a first lens assembly 911 and an optical fiber bracket 912. A wrapping cavity 9112 is provided at one end of the first lens assembly 911, and an opening is provided at one side of the wrapping cavity 9112. An optical fiber 9127 is fixed at one end of the optical fiber bracket 912. The optical fiber bracket 912 carries the optical fiber 9127 and is inserted into the wrapping cavity 9112 through the opening to achieve the connection between the optical fiber bracket 912 and the first lens assembly 911. After the optical fiber bracket 912 is inserted into the wrapping cavity 9112, the wrapping cavity 9112 wraps the optical fiber bracket 912, and the first end face of the optical fiber bracket 912 is buried in the wrapping cavity 9112. The first sealing glue is applied on the glue application surface 91124 of the wrapping cavity 9112, so that the first end face of the optical fiber bracket 912 is far away from the position where the first sealing glue is located, thereby making it difficult for the first end face of the optical fiber bracket 912 to be contaminated by the first sealing glue. After the first sealant is cured, a second sealant is formed. The second sealant is located around the side of the optical fiber bracket 912 and the glue-dispensing surface 91124 of the wrapping cavity 9112 to isolate the coolant. That is, after the optical fiber bracket 912 is inserted into the wrapping cavity 9112, the first sealant is applied to the glue-dispensing surface 91124 of the wrapping cavity 9112 so that the first sealant completely seals the gap between the wrapping cavity 9112 and the optical fiber bracket 912. The first sealant is accumulated between the wrapping cavity 9112 and the optical fiber bracket 912. In this way, after the first sealant is cured, a second sealant is formed to ensure the sealing of the connection between the first lens assembly 911 and the optical fiber bracket 912, thereby preventing the coolant from penetrating.

[0110] After the optical fiber bracket 912 is inserted into the wrapping cavity 9112, the four side surfaces of the optical fiber bracket 912 are respectively arranged corresponding to the four side walls corresponding to the wrapping cavity 9112, and the first end surface of the optical fiber bracket 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 spotting surface 91124 of the wrapping cavity 9112, that is, the first end surface of the optical fiber bracket 912 is located in the wrapping cavity 9112, away from the glue spotting surface 91124 of the wrapping cavity 9112.

[0111] A first lens 9116 is arranged in the wrapping cavity 9112. The first lens 9116 is arranged 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.

[0112] When coupling and mounting the first lens assembly 911 on the circuit board 300, a suction nozzle is required to suck the first lens assembly 911, so that there is a gap between the first lens assembly 911 and the circuit board 300, and then couple with the optical chip on the circuit board 300. If the upper surface of the first lens assembly 911 is not flat or there is not a large enough plane, there is no place to place the suction nozzle on the upper surface of the first lens assembly 911. Therefore, it is necessary to set a larger suction plane on the upper surface of the first lens assembly 911 to place the suction nozzle, so that the suction nozzle can suck the first lens assembly 911. 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, which is used to provide a larger suction plane for the suction nozzle to facilitate the suction nozzle to suck the first lens assembly 911.

[0113] like Figure 7 , Figure 8 and Fig. 9 As shown, the first lens assembly 911 is provided with an optical port slot 9111 in an area other than 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 is formed with a reflecting surface 9115, and 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, and the first lens 9116 reflects the light beam received by the optical fiber transmission through the reflecting surface 9115, and the reflected light signal is incident on the optical chip 303 (specifically the optical receiving chip 3032).

[0114] 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 make the reflection surface 9115 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.

[0115] 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 port groove 9111 is less than 1 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 port groove 9111 is 1.8-2.2 mm.

[0116] 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. The 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, so as to prevent the coolant from penetrating into the reflective surface in the optical port groove 9111; since 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.

[0117] Since an opening is provided on the top surface of the optical port slot 9111, it is convenient for the plastic mold to be demoulded. In order to prevent the coolant from penetrating into the reflective surface 9115 through the opening of the optical port slot 9111, in some embodiments, a blocking component is provided on the top surface of the opening of the optical port slot 9111, and the blocking component is fixed to the top surface of the optical port slot 9111 to seal the opening of the optical port slot 9111, thereby preventing the coolant from penetrating through the opening of the optical port slot 9111.

[0118] In some embodiments, the blocking assembly includes a sealing cover plate, one end of which covers the optical fiber bracket, and the other end of which covers the optical port slot to seal the opening of the optical port slot 9111.

[0119] In some 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 .

[0120] 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.

[0121] In some embodiments, the material of the blocking sheet 913 may be, but is not limited to, polyimide.

[0122] The size of the baffle 913 is larger than the size of the opening 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, and the third sealing member seals the opening of the baffle 913 and the optical port slot 9111 to reduce the penetration of the coolant into the optical port slot 9111, and ensure that the optical port slot 9111 is isolated from the coolant.

[0123] However, the blocking piece 913 and the opening of the optical port slot 9111 are only bonded by adhesive, and the adhesive strength of the adhesive is insufficient, resulting in poor connection stability between the blocking piece 913 and the opening of the optical port slot 9111, and further resulting in poor connection sealing between the blocking piece 913 and the opening of the optical port slot 9111, that is, the blocking piece 913 and the opening of the optical port slot 9111 cannot be completely sealed. In order to achieve complete sealing between the blocking piece 913 and the opening of the optical port slot 9111, in some embodiments, a first sealing glue 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 component is formed. The third sealing component completely seals the opening of 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.

[0124] Since the first sealing glue can move, the movement of the first sealing glue can easily lead to the third sealing member after the first sealing glue is cured to be unable to completely seal the opening of the baffle 913 and the optical port slot 9111. In order to solve this problem, in some embodiments, a storage groove is provided on the outside of the optical port slot 9111, and the optical port slot 9111, the baffle 913 and the third sealing member are provided in the storage groove, and the third sealing member is located at the top and outer side wall of the baffle 913. The first sealing glue is injected into the storage groove so that the first sealing glue is coated on the top of the baffle 913, the connection between the baffle 913 and the surface of the first lens assembly 911, and the surface of the first lens assembly 911, and the third sealing member is formed after the first sealing glue is cured. The third sealing member is located on the top and outer side wall of the baffle 913 to achieve 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.

[0125] In some embodiments, a storage groove is provided on the outside of the optical port groove 9111, and the optical port groove 9111, the baffle 913 and the third sealing member are provided in the storage groove, and a rubber isolation protrusion is provided at one end of the groove wall of the optical port groove 9111. The storage groove can fix the third sealing member at a preset position to achieve complete sealing between the baffle 913 and the opening to prevent the coolant from penetrating; the first sealing glue in the storage groove penetrates into the rubber isolation protrusion of the optical port groove 9111, and the first sealing glue is coated on the rubber isolation protrusion, 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 reflecting surface 9115, thereby ensuring that the reflecting surface 9115 is isolated from the external coolant and is not affected by the first sealing glue.

[0126] In some embodiments, a storage groove is provided on the outside of the optical port groove 9111, and the storage groove is provided with the optical port groove 9111, the baffle 913 and the third sealing member, and a rubber isolation 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 isolation protrusion. The storage groove can fix the third sealing member at a preset position to achieve complete sealing between the baffle 913 and the opening to prevent the coolant from penetrating; the first sealing glue in the storage groove penetrates into the first sealing glue of the optical port groove 9111, and the first sealing glue of the optical port groove 9111 is coated on the rubber isolation protrusion, 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.

[0127] In some embodiments, the optical module includes two sets of staggered optical transceiver components. When the two optical transceiver components are placed too close, the optical fiber connecting one optical transceiver component needs to cross the other optical transceiver component, which can easily cause the bending radius of the optical fiber to be too small, affecting the optical fiber transmission. In order to solve this problem, the first lens assembly 911 is provided with an inclined surface 9113, and 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 inclined 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.

[0128] like Fig. 9 As shown, a cover cavity 9124 is provided on the side of the first lens assembly 911 facing the circuit board 300, and the cover cavity 9124 is recessed from the bottom surface to the top surface of the first lens assembly 911. When the first lens assembly 911 is sealed and installed with the circuit board 300, the cover cavity 9124 forms a sealed cavity, and optoelectronic devices such as the optical chip 303 and the optical matching chip 302 are located in the sealed cavity, which can prevent the coolant from penetrating into the first lens assembly 911 and causing the failure of optoelectronic devices such as the optical chip 303 and the optical matching chip 302.

[0129] A second lens 9117 is provided on the inner wall of the housing cavity 9124, and 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 is a light transmitting chip, so that the light beam emitted by the light transmitting chip is converted into a collimated light beam via the transmitting collimating lens, and the collimated light beam is projected to the reflective surface 9115 for reflection, and the reflected collimated light beam is 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 is a light receiving chip, so that the receiving light beam is projected to the reflective surface 9115 via the first lens 9116, and the receiving light beam is reflected by the reflective surface 9115, and the reflected receiving light beam is coupled to the light receiving chip via the receiving coupling lens.

[0130] 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 to form the twelfth seal, 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.

[0131] Fig.10 FIG. 1 is an assembly diagram of a first lens assembly and a baffle according to some embodiments. Fig.11 FIG. 4 is an exploded view of a first lens assembly and a blocking piece according to some embodiments. Fig.12 FIG. 4 is a structural diagram of a first lens assembly provided in accordance with some embodiments at a first viewing angle. Fig.10 , Fig.11 and Fig.12As shown, in some embodiments, the storage groove includes a first storage groove 9120, and a baffle 913 and a third sealing member are arranged in the first storage groove 9120, and the third sealing member is located at the top and outer side wall of the baffle 913. After the baffle 913 is attached to the first storage groove 9120, a first sealing glue is filled in the first storage groove 9120, and the height of the first sealing glue is higher than the height of the baffle, so that the first sealing glue is accumulated on the top of the baffle 913, and the third sealing member is formed after the first sealing glue is cured. The first storage groove 9120 defines the position of the third sealing member on the surface of the first lens assembly 911, and prevents the third sealing member from deviating from the preset position, so as to achieve a stable connection between the baffle 913 and the opening of the optical port groove 9111.

[0132] 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.

[0133] In some embodiments, the storage slot also includes a second storage slot 9121, which is formed by the first storage slot 9120 being recessed inwardly, a third seal and a second storage slot 9121 are placed in the first storage slot 9120, a baffle 913 is placed in the second storage slot 9121, and the third seal is located at the top and outer side wall of the baffle 913. After the baffle 913 is attached to the second storage slot 9121, the first storage slot 9120 is filled with the first sealing glue, so that the first sealing glue is accumulated on the top of the baffle 913, and the third seal is formed after the first sealing glue is cured. The second storage slot 9121 defines the position of the baffle 913 on the surface of the first lens assembly 911, and prevents 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.

[0134] The length dimension of the second storage groove 9121 is greater than the length dimension of the baffle 913, or the width dimension of the second storage groove 9121 is greater than the width dimension of the baffle 913, so that the baffle 913 and the third sealing member are 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 sealing glue is filled in the first storage groove 9120, so that the first sealing glue is accumulated on the outer side wall and the top of the baffle 913, and the third sealing member is formed after the first sealing glue is cured.

[0135] like Fig.10 , Fig.11 and Fig.12As shown, in some embodiments, the rubber-isolating protrusions include first rubber-isolating protrusions 9122, which are formed by protruding outward from the groove wall of the optical port groove 9111, and the first rubber-isolating protrusions 9122 narrow the optical port groove 9111 to form a deep well groove. Since the first sealing glue is viscous, it can only cover the first rubber-isolating protrusions 9122 in the upper part of the deep well groove, 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.

[0136] In some embodiments, the first rubber spacer protrusion 9122 is formed by a groove wall of the optical port groove 9111 protruding outward, and 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.

[0137] In some embodiments, the first rubber spacer protrusion 9122 is formed by all the groove walls of the optical port groove 9111 protruding outward, and 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.

[0138] In some embodiments, the first rubber spacer protrusion 9122 is formed by all the groove walls of the light port groove 9111 protruding outward, and the first rubber spacer protrusion 9122 includes a plurality of closed annular protrusions, and the plurality of closed annular protrusions are connected in sequence. The sizes of the plurality of closed annular protrusions are different. The plurality of closed annular protrusions form N1 steps from small to large according to the size. The N1 step and the opening of the light port groove 9111 form N1+1 steps, and N1≥2.

[0139] The closed annular protrusion with the same width narrows the size of the light opening groove 9111 relative 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.

[0140] 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 light 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.

[0141] In some embodiments, the rubber-isolating protrusions further include a second rubber-isolating protrusion 9123, which is formed by the first groove wall (referring to the groove wall where the reflective surface is located in the optical port groove 9111) of the first rubber-isolating protrusion 9122 protruding outward, and the second rubber-isolating protrusion 9123 further narrows the optical port groove 9111 to form a deep well groove. Since the first sealant is viscous, it can only cover the first rubber-isolating protrusion 9122 and the second rubber-isolating protrusion 9123 in the upper part of the deep well groove, and the air in the lower part of the deep well groove supports the first sealant, so that the first sealant 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 sealant.

[0142] In some embodiments, the second rubber spacer protrusion 9123 is formed by the first groove wall of the optical port groove 9111 protruding outward, and 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.

[0143] In some embodiments, the second rubber spacer protrusion 9123 is formed by the first groove wall of the optical port groove 9111 protruding outward, and the second rubber spacer protrusion 9123 includes a plurality of non-closed annular protrusions, and the plurality of non-closed annular protrusions are connected in sequence. The sizes of the plurality of non-closed annular protrusions are different, and the plurality of non-closed annular protrusions form N2 steps from small to large according to the size. The N2 steps, the first rubber spacer protrusion 9122 and the opening of the optical port groove 9111 form N1+N2+1 steps, N1≥2, N2≥2.

[0144] like Fig.12 As shown, 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 arranged corresponding to the emitting collimating lens and the light emitting chip 3031, and the receiving reflection surface 9115b is arranged 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.

[0145] In some embodiments, there is only one optical port slot 9111, and no distinction is made between an emitting optical port slot and a receiving optical port slot. The optical port slot is provided with a first rubber spacer protrusion 9122, a second rubber spacer protrusion 9123 and a reflective surface 9115, and the reflective surface 9115 includes an emitting reflective surface 9115a and a receiving reflective surface 9115b, and the emitting reflective surface 9115a and the receiving reflective surface 9115b are connected. The first lens assembly 911 is provided with only one optical port slot 9111, which is convenient for processing.

[0146] In some embodiments, the optical port slot 9111 includes an emission optical port slot 9111a and a receiving optical port slot 9111b, and the emission optical port slot 9111a is separated from the receiving optical port slot 9111b. An emission spacer protrusion is provided in the emission optical port slot 9111a, and a receiving spacer protrusion is provided in the receiving optical port slot 9111b, and the emission spacer protrusion and the receiving spacer protrusion are not connected. The emission spacer protrusion includes a first emission spacer protrusion 9122a, and a second emission spacer protrusion 9123a protruding outward is provided at one end of the first groove wall of the first emission spacer protrusion 9122a, and an emission reflection surface 9115a is formed at the other end of the first groove wall of the first emission spacer protrusion 9122a, and the first emission spacer protrusion 9122a and the second emission spacer protrusion 9123a are stepped to narrow the emission optical port slot 9111a. The receiving glue spacer protrusion includes a first receiving glue spacer protrusion 9122b, one end of the first groove wall of the first receiving glue spacer protrusion 9122b is provided with a second receiving glue spacer protrusion 9123b protruding outward, the other end of the first groove wall of the first receiving glue spacer protrusion 9122b forms a receiving reflection surface 9115b, the first receiving glue spacer protrusion 9122b and the second receiving glue spacer protrusion 9123b are stepped to narrow the receiving light port groove 9111b, and the emitting reflection surface 9115a and the receiving reflection surface 9115b are not connected.

[0147] The first lens assembly 911 is provided with an emitting light port slot 9111a and a receiving light port slot 9111b, and the emitting light port slot 9111a and the receiving light port slot 9111b are separated, 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 not affected by the first sealing glue.

The first sealing glue is applied on the glue-pointing surface 91124, and the first sealing glue is cured to form a second sealing member, which is located on each side of the optical fiber bracket 912 and around the glue-pointing surface 91124 of the package cavity 9112. That is, the first sealing glue is applied on the outer side surface 91125 of the first package side wall 91121, the outer side surface of the second package side wall 91123, the outer side surface of the third package side wall and the fourth package side wall, and the first sealing glue is cured to form a second sealing member, which is located on each side of the optical fiber bracket 912 and around the outer side surface of the first package side wall 91121, the outer side surface of the second package side wall 91123, the outer side surface of the third package side wall and the fourth package side wall.

[0150] The first wrapping side wall 91121 is a side wall of the wrapping cavity 9112 away from the circuit board 300, and the fourth wrapping side wall is a side wall of the wrapping cavity 9112 close to the circuit board 300. Then, the outer side surfaces of the three side walls of the wrapping cavity 9112 away from the circuit board 300 and one side wall of the wrapping cavity 9112 close to the circuit board 300 form a glue dispensing surface 91124 of the wrapping cavity 9112. That is, the second sealing member is located around each side surface of the optical fiber bracket 912 and the outer side surfaces of the three side walls of the wrapping cavity 9112 away from the circuit board 300 and one side wall of the wrapping cavity 9112 close to the circuit board 300.

[0151] In some embodiments, the outer side surface of the second package sidewall 91123 includes a first outer side portion 91126 and a second outer side portion 91127, the first outer side portion 91126 is connected to the second outer side portion 91127, the first outer side portion 91126 is also connected to the outer side surface 91125 of the first package sidewall 91121, and the first outer side portion 91126 is located between the outer side surface 91125 of the first package sidewall 91121 and the second outer side portion 91127. The outer side surface 91125 of the first package sidewall 91121 and the first outer side portion 91126 are vertical surfaces, and the second outer side portion 91127 is an inclined surface.

[0152] 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.

[0153] like Fig.14 As shown, 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, so that 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.

[0154] The first end face of the optical fiber bracket 912 is also provided with an optical fiber hole, and the second end face of the optical fiber bracket 912 (the opposite side of the first end face of the optical fiber bracket 912) is provided with an optical fiber jack, and the optical fiber hole 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 bracket 912, and can also protrude from the first end face of the optical fiber bracket 912.

[0155] Insert the optical fiber 9127 into the optical fiber holder 912 through the optical fiber socket, and use the first sealing glue to seal all the gaps between the optical fiber 9127 and the optical fiber socket. The first sealing glue is added to the periphery of the contact between the optical fiber 9127 and the optical fiber socket, and is accumulated on the second end faces 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 socket.

[0156] like Fig.14 As shown, an observation hole 9125 is also provided at the upper end of the optical fiber bracket 912, and the observation hole 9125 is communicated with the optical fiber hole in the optical fiber bracket 912, and the insertion of the optical fiber 9127 into the optical fiber bracket 912 can be checked through the observation hole 9125. After the optical fiber 9127 is inserted into the optical fiber bracket 912 through the optical fiber insertion hole, the first sealing glue can be added to the observation hole 9125 to form a sealing member, thereby sealing the observation hole 9125 through the sealing member to prevent the coolant from penetrating into the interior of the optical fiber bracket 912 through the observation hole 9125.

[0157] 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.

[0158] 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 directly placed on the optical fiber bracket 912 to facilitate the dispensing needle to dispense glue to the gap between the first wrapping side wall 91121 and the optical fiber bracket 912.

[0159] In some embodiments, the length dimension of the fourth package side wall is smaller than the length dimension of a side surface of the optical fiber holder 912 corresponding to the fourth package side wall, that is, the area of ​​the optical fiber holder 912 other than the optical fiber 9127 is partially located outside the package cavity 9112. Since the distance between the optical fiber holder 912 and the circuit board 300 is small, it is not convenient for the glue needle to penetrate deep into the space between the optical fiber holder 912 and the circuit board 300, that is, it is not convenient to glue the gap between the fourth package side wall and the optical fiber holder 912.

[0160] 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 of the optical fiber bracket 912 corresponding to the fourth wrapping side wall, that is, the area of ​​the optical fiber bracket 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 of glue in the gap between the fourth wrapping side wall and the optical fiber bracket 912.

[0161] 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 convenient for the glue dispensing needle to dispense glue in the gap between the wrapping cavity 9112 and the optical fiber bracket 912.

[0162] Fig.15 FIG. 4 is a first structural diagram of a first lens assembly provided in some embodiments at a third viewing angle.

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

[0163] In some embodiments, the second sealant does not extend beyond the first air hole 9119a in the gap between the first wrapping side wall 91121 and the top surface of the optical fiber bracket 912, so that the second sealant 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.

[0164] Fig.16 FIG. 4 is a second structural diagram of a first lens assembly provided in some embodiments at a third viewing angle. Fig.16 As shown, in some embodiments, the air hole 9119 includes a second air hole 9119b and a vent hole 9119c, the second air hole 9119b is located above the cover cavity 9124, the vent hole 9119c is located below the wrapping cavity 9112, and the second air hole 911b is connected to the cover cavity 9124. The air expanded in the cover cavity 9124 is released through the second air hole 911b, and the air expanded in the wrapping cavity 9112 is released into the cover cavity 9124 through the vent hole 9119c, and then released through the second air hole 9119b, and the second air hole 9119b is filled with the second sealing glue, and the second sealing glue is cured to form a twelfth sealing member, and the twelfth sealing member blocks the second air hole 911b to prevent the coolant from penetrating into the cover cavity 9124.

The air expanded in the housing cavity 9124 is released into the wrapping cavity 9112 through the vent hole 9119c, and then released out through the first air hole 9119a, the air expanded in the wrapping cavity 9112 is released out through the first air hole 9119a, the first air hole 9119a is filled with the second sealing glue, the second sealing glue is cured to form the twelfth sealing member, and the twelfth sealing member blocks the first air hole 9119a to prevent the coolant from penetrating into the housing cavity 9124.

[0166] like Fig.15 , Fig.16 and Fig.17 As shown, 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.

[0167] Fig.18 A first optical path diagram of a first optical transceiver component provided according to some embodiments. Fig.19 FIG. 4 is a second optical path diagram of a second optical transceiver component provided according to some embodiments. Fig.18 As shown, in some embodiments, the angle between the transmitting reflection surface 9115a and the horizontal plane is the same as the angle between the receiving reflection surface 9115b and the horizontal plane, the angle between the transmitting reflection surface 9115a and the horizontal plane and the angle between the receiving reflection surface 9115b and the horizontal plane are both 45°, the angle between the plane where the transmitting collimating lens 9117a is located and the horizontal plane and the angle between the plane 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.

[0168] The optical emission chip 3031 emits a divergent light beam upward, which is converted into a collimated light beam by the emission collimating lens 9117a. The collimated light beam is emitted to the emission reflection surface 9115a for reflection. The reflected collimated light beam is converted into a convergent light beam by the emission coupling lens and coupled to the optical fiber, and the optical fiber is transmitted to the optical receiving chip in the optical module at the other end of the optical fiber. The light beam emitted by the optical emission chip at the other end of the optical fiber is transmitted to the receiving collimating lens via the optical fiber, and is collimated into a collimated light beam by the receiving collimating lens. The collimated light beam is emitted to the receiving reflection surface 9115b for reflection. The reflected collimated light beam is vertically downward, coupled by the receiving coupling lens 9117b, and vertically incident on the optical receiving chip 3032.

[0169] 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 are combined into a reflection surface 9115, which is convenient for processing and more accurate.

[0170] The angle between the receiving reflection surface 9115b and the horizontal plane is 45°, and the part of the light beam vertically incident on the light receiving chip 3032 returns to the optical fiber along the original path, affecting the performance of the light transmitting chip at the other end of the optical fiber. Fig.19 As shown, in some embodiments, the angle between the emitting reflection surface 9115a and the horizontal plane is 45°, and the angle α between the receiving reflection surface 9115b and the horizontal plane is less than 45°. For example, the angle α between the receiving reflection surface 9115b and the horizontal plane is 30° to 38°, and the angle α between the receiving reflection surface 9115b and the horizontal plane is 39° to 42°.

[0171] The angle between the emitting reflection surface 9115a and the horizontal plane is 45°, the angle between the surface where the emitting collimating lens 9117a is located and the horizontal plane is 0°, the angle between the receiving reflection surface 9115b and the horizontal plane is α<45°, the surface where the receiving coupling lens 9117b is located is moved backward relative to the surface where the emitting collimating lens 9117a is located, and is tilted, that is, the angle between the surface where the receiving coupling lens 9117b is located and the horizontal plane changes from 0° to β, and the emitting 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 reflection surface 9115b and the horizontal plane is 45°-α, and the angle deflection angle β between the surface where the receiving reflection surface 9115b is located and the horizontal plane is 2γ, that is, the angle β between the surface where the receiving coupling lens 9117b is located and the horizontal plane is 2*(45°-α).

[0172] 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.

[0173] The optical transmitter chip 3031 emits a divergent light beam upward, which is converted into a collimated light beam by the emission collimating lens 9117a. The collimated light beam is projected to the emission reflection surface 9115a for reflection. The reflected collimated light beam is converted into a convergent light beam by the emission coupling lens and coupled to the optical fiber, and the optical fiber is transmitted to the optical receiving 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 to the receiving collimating lens via the optical fiber, and is collimated into a collimated light beam by the receiving collimating lens. The collimated light beam is projected to the receiving reflection surface 9115b for reflection. The reflected collimated light beam is tilted downward, and after being coupled by the receiving coupling lens 9117b, it is tilted to the optical receiving chip 3032. The light beam that is tilted to the optical receiving chip 3032 is reflected at the optical receiving chip 3032. The reflected light beam does not return along the original path, but is tilted upward, thereby preventing the light beam that returns to the optical fiber 9127 from affecting the performance of the optical transmitter chip at the other end of the optical fiber 9127.

[0174] 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.

[0175] 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 into the reflection surface 9115.

An optical chip is arranged on the circuit board, the first lens assembly cover is arranged on the optical chip, a first seal is arranged between the first lens assembly and the circuit board, the first seal is located on the outer wall of the first lens assembly and the surface of the circuit board, so that the gap between the first lens assembly and the circuit board is completely sealed by the first seal, and the first seal is accumulated between the circuit board and the outer wall of the first lens assembly to ensure the sealed connection between the first lens assembly and the circuit board. A wrapping cavity is provided at one end of the first lens assembly, and the top surface of the wrapping cavity is flush with the top surface of the area of ​​the first lens assembly except the wrapping cavity, so as to facilitate coupling and mounting the first lens assembly on the circuit board; an opening is provided on one side of the wrapping cavity, and the optical fiber holder is inserted into the wrapping cavity through the opening, and the first end surface of the optical fiber holder is buried in the wrapping cavity, and the first sealing glue is applied on the glue application surface of the wrapping cavity, so that the first end surface of the optical fiber holder is far away from the position where the first sealing glue is located, thereby making it difficult for the first end surface of the optical fiber holder to be contaminated by the first sealing glue; after the first sealing glue is cured, a second sealing member is formed, and the second sealing member is located on each side surface of the optical fiber holder and the outer side surfaces of the three side walls of the wrapping cavity away from the circuit board and around a side wall of the wrapping cavity close to the circuit board, so that the gap between the optical fiber holder and the wrapping cavity is completely sealed by the second sealing member to ensure the sealed connection between the optical fiber holder and the first lens assembly, thereby isolating the cooling liquid. The package cavity has a first air vent, which is located on a side wall of the package cavity away from the circuit board. 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, so that the air in the package cavity can be released. A twelfth seal is arranged in the first air vent, and the twelfth seal is used to block the first air vent to prevent the coolant from penetrating into the first lens assembly through the first air vent. The first lens assembly is provided with a concave optical port groove and a blocking assembly, and the blocking assembly covers the optical port groove to prevent the coolant from penetrating into the optical port groove; the other end of the groove wall of the optical port groove forms a reflecting surface, and the reflecting surface is used to reflect the light generated by the optical chip into the package cavity, so that the light is input into the optical fiber holder in the package cavity to realize light reflection. A rubber partition protrusion is formed at one end of the groove wall of the optical port groove, and the rubber partition protrusion is used to narrow the optical port groove and support the seal in the optical port groove to prevent the seal in the optical port groove from penetrating into the reflecting surface.

[0177] Fig. 20 It is a structural diagram of a second optical transceiver component provided according to some embodiments. Fig.21 An exploded view of a second optical transceiver component provided according to some embodiments. Fig. 22 FIG. 4 is a cross-sectional view of a second optical transceiver component provided according to some embodiments. Fig. 20 , Fig.21 and Fig. 22As shown, in some embodiments, the second optical transceiver component 902 includes a second lens assembly 921, an optical fiber bracket 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 disposed at one end of the second lens assembly 921. An optical fiber 9223 is fixed at one end of the optical fiber bracket 922. The optical fiber bracket 922 carries the optical fiber 9223 and is inserted into the snap-in groove 9212 to achieve connection between the optical fiber bracket 922 and the second lens assembly 921. After the optical fiber bracket 922 is inserted into the snap-in groove 9212, a second sealing member is disposed between the optical fiber bracket 922 and the snap-in groove 9212. The second sealing member is located between each side wall of the snap-in groove 9212 and each side surface corresponding to the optical fiber bracket 922. After the optical fiber holder 922 is inserted into the card slot 9212, the first sealing glue is used to seal all the gaps between the side walls of the card slot 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 card slot 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, so as to prevent the infiltration of the coolant. One end of the sealing cover plate 923 covers the optical port groove 9211 of the second lens assembly 921, and the other end of the sealing cover plate 923 covers the optical fiber holder 922 on the card slot 9212. The first end surface of the optical fiber holder 922 is located on the bottom surface of the sealing cover plate 923. The first sealing glue is applied to the outer wall of the sealing cover plate 923 so that the first end face of the optical fiber bracket 922 is far away from the position of the first sealing glue, so that the first end face of the optical fiber bracket 922 is not easily contaminated by the first sealing glue. After the first sealing glue is cured, a fifth sealing member is formed, and the fifth sealing member is located on the outer wall of the sealing cover plate 923 and the second lens assembly 921 and the optical fiber bracket 922 to isolate the cooling liquid. That is, after the sealing cover plate 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 plate 923 so that the first sealing glue completely seals the gap between the sealing cover plate 923 and the second lens assembly 921 and the optical fiber bracket 922, and the first sealing glue is accumulated between the sealing cover plate 923 and the second lens assembly 921 and the optical fiber bracket 922. In this way, the fifth sealing member is formed after the first sealing glue is cured to ensure the sealing of the connection between the sealing cover plate 923 and the second lens assembly 921 and the optical fiber bracket 922, so as to prevent the infiltration of the cooling liquid.

[0178] like Fig. 22As shown, a first lens 9216 is arranged in the snap-in groove 9212. The first lens 9216 is arranged 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.

[0179] like Fig.21 and Fig. 22 As shown, the second lens assembly 921 is provided with an optical port slot 9211, 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 forms a reflecting surface 9215, and the reflecting surface 9215 is arranged opposite to the first lens 9216, so that 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, and 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).

[0180] The reflecting surface 9215 includes an emitting reflecting surface and a receiving reflecting surface. The emitting reflecting surface is arranged corresponding to the emitting collimating lens and the light emitting chip, and the receiving reflecting surface is arranged 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.

[0181] Since an opening is provided on the top surface of the optical port slot 9211, it is convenient for the plastic mold to be demoulded. In order to prevent the coolant from penetrating into the second lens assembly 921 through the opening of the optical port slot 9211, the sealing cover plate 923 is covered on 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 to reduce the coolant from penetrating into the optical port slot 9211 and ensure that the optical port slot 9211 is isolated from the coolant.

[0182] In some embodiments, in order to prevent the first sealing glue from flowing into the reflective surface 9215, a sealing protrusion is provided at one end of the groove wall of the optical port groove 9211. The sealing protrusion narrows the optical port groove 9211 to form a deep well groove. Since the first sealing glue is viscous, the first sealing glue can only cover the upper part of the deep well groove (i.e., the sealing protrusion of the optical port groove 9211), 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 9215, thereby ensuring that the reflective surface 9215 is isolated from the external coolant and is not affected by the first sealing glue.

[0183] In some embodiments, the rubber-isolating protrusions include first rubber-isolating protrusions, which are formed by the groove wall of the optical port groove 9211 protruding outward, and the first rubber-isolating protrusions narrow the optical port groove 9211 to form a deep well groove. Since the first sealing glue is viscous, it can only cover the first rubber-isolating protrusions in the upper part of the deep well groove, 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 reflecting surface 9215, thereby ensuring that the reflecting surface 9215 is isolated from the external coolant and is not affected by the first sealing glue.

[0184] In some embodiments, the rubber-isolating protrusion further includes a second rubber-isolating protrusion, which is formed by the first groove wall of the first rubber-isolating protrusion (referring to the groove wall where the reflective surface is located in the optical port groove 9211) protruding outward, and the second rubber-isolating protrusion further narrows the optical port groove 9211 to form a deep well groove. Since the first sealing glue is viscous, it can only cover the first rubber-isolating protrusion and the second rubber-isolating protrusion in the upper part of the deep well groove. 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 9215, thereby ensuring that the reflective surface 9215 is isolated from the external coolant and is not affected by the first sealing glue.

[0185] In some embodiments, the second lens assembly 921 is provided with an inclined surface 9213, which is inclined along the top surface of the second lens assembly 921 toward a side of the second lens assembly 921 away from the optical fiber bracket 912, that is, the inclined surface 9213 is an inclined surface inclined downward. The rear optical fiber 9223 is inclined upward along the inclined surface 9213, so that the optical fiber 9223 has a larger bending radius, avoiding the optical fiber transmission problem caused by the optical fiber radius being too small.

[0186] like Fig. 22As shown, a cover cavity 9222 is provided on the side of the second lens assembly 921 facing the circuit board 300, and a second lens 9217 is provided on the inner wall of the cover 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 is a light transmitting chip. In this way, the light beam emitted by the light transmitting chip is converted into a collimated light beam via the transmitting collimating lens, and the collimated light beam is projected to the reflective surface 9215 for reflection. The reflected collimated light beam is 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 is a light receiving chip. In this way, the received light beam is projected to the reflective surface 9215 via the first lens 9216, and the received light beam is reflected by the reflective surface 9215. The reflected received light beam is coupled to the light receiving chip via the receiving coupling lens.

[0187] In some embodiments, the sealing cover plate 923 and the snap-in groove 9212 form a wrapping cavity, and a first air hole is provided on the sealing cover plate 923. The expanded air in the wrapping cavity is released through the first air hole, and the first air hole is filled with the second sealing glue. The second sealing glue is cured to form a twelfth seal, and the twelfth seal is used to block the first air hole to prevent the coolant from penetrating into the wrapping cavity through the first air hole.

[0188] In some embodiments, a second air hole is further provided on the second lens assembly 921. The second air hole 9219 is located above the cover cavity 9222. The second air hole 9219 is communicated with the cover cavity 9222. The expanded air in the cover cavity 9222 is released through the air hole 9219 to prevent the coolant from seeping in.

[0189] Fig.23 FIG. 4 is a structural diagram of a second lens assembly provided according to some embodiments.

[0198] 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.

The fourth sealing glue is applied to the gap between the first end face of the optical fiber bracket 932 and the third lens assembly 931. The viscosity of the fourth sealing glue is greater than the viscosity of the first sealing glue, so that the fourth sealing glue between the first end face of the optical fiber bracket 932 and the third lens assembly 931 will not penetrate into the first end face of the optical fiber bracket 932. After the fourth sealant is cured, a thirteenth sealant is formed to achieve a sealed connection between the first end face of the optical fiber bracket 932 and the third lens assembly 931.

[0231] In some embodiments, the optical cable 108 further includes an isolator 183, which is coated on the middle of the outer side of the optical cable body 182. The isolator 183 is used to isolate the cooling liquid from one end of the optical cable 108 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.

[0233] Fig.37 FIG. 1 is an exploded view of an optical cable fixture according to some embodiments. Fig.38 The figure is an assembly diagram of a clamp, a first crimping ring, and a second crimping ring according to some embodiments. Fig.39 FIG. 1 is an assembly diagram of a clamp and a first crimping ring according to some embodiments. Fig.37 , Fig.38 and Fig.39 As shown, in some embodiments, the optical cable fixing part 181 includes a clamp 1811, one end of the clamp 1811 is clamped at the optical port of the optical module 200, and the other end of the clamp 1811 is arranged adjacent to the cable skin 1821. The inner side of the clamp 1811 has a first cavity, and the optical fiber 1822 and the fifth sealing glue are arranged in the first cavity. After the fifth sealing glue is cured, a seventh sealing member is formed, and the seventh sealing member fills the gap between the inner side wall of the clamp 1811 and the optical fiber 1822. The seventh sealing member is seamlessly connected to the optical fiber 1822 to prevent the cooling liquid inside the optical module 200 from penetrating into the interior of the optical cable body 182 through the first cavity of the clamp 1811.

[0234] In order to make the fifth sealing glue not only have a sealing function but also have a function of protecting the optical cable, in some embodiments, the fifth sealing glue is a soft glue. For example, the fifth sealing glue is silicone. The clamp 1811 includes a clamp body 1815 and a stop protrusion 1816. The clamp body 1815 is located at one end of the clamp 1811, and the stop protrusion 1816 is located at the other end of the clamp 1811 (close to the optical module relative to the clamp body 1815). The inner side of the clamp body 1815 and the inner side of the stop protrusion 1816 enclose a first cavity.

[0235] In some embodiments, the optical cable fixing member 181 further includes a second crimping ring 1813, one end of the second crimping ring 1813 is crimped to the reinforcing wire 1823 outside the clamp 1811, and the other end of the second crimping ring 1813 is crimped to the cable skin 1821 to compress the optical cable fixing member 181 and the reinforcing wire 1823 to ensure that the tension of the optical cable 108 meets the requirements. The second crimping ring 1813 is pushed to the stop protrusion 1816 outside the clamp 1811, and the end of the reinforcing wire 1823 (Kevlar) passes over the second crimping ring 1813 to ensure that the tension of the optical cable body 182 meets the requirements.

[0236] 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 fixture 181 further includes a first crimping ring 1812 and a second crimping ring 1813, the first crimping ring 1812 is covered on the outside of the clamp body 1815, the first crimping ring 1812 is located in front of the stop protrusion 1816, and a reinforcing wire 1823 is provided between the first crimping ring 1812 and the outside of the clamp 1811. 3, so as to crimp the reinforcing 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 middle of the second crimping ring 1813 is crimped onto the reinforcing wire 1823 on the outside of the clamp body 1815, and the other end of the second crimping ring 1813 is crimped onto the cable sheath 1821, so as to compress the optical cable fixing 181 and the reinforcing wire 1823, thereby ensuring that the tension of the optical cable 108 meets the requirements. Push the first crimping ring 1812 to the stop protrusion 1816 on the outside of the clamp 1811, wrap the end of the reinforcing wire 1823 (Kevlar) inside the first crimping ring 1812, and crimp the first crimping ring 1812 so 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.

[0237] In some embodiments, the reinforcing wire 1823 must not extend beyond the left end of the first crimping ring 1812 to prevent the cooling liquid outside the optical module from penetrating into the optical fiber 1822 inside the optical cable body 182 through the reinforcing wire 1823 .

[0238] After the second crimping ring 1813 is crimped, it is necessary to observe whether the second crimping ring 1813 is flat, whether there are damaged threads, and whether the first crimping ring 1812 is clearly visible. After observing that the second crimping ring 1813 is flat, has no damaged threads, and the first crimping ring 1812 is clearly visible, a tensile test is performed to ensure that the tensile force of the optical cable reaches 15Kg / min.

[0239] 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 sealing member not only blocks the gap between the first crimping ring 1812 and the second crimping ring 1813 to ensure the sealed connection between the first crimping ring 1812 and the second crimping ring 1813, but also blocks the gap between the first crimping ring 1812 and the clamp body 1811 to ensure the sealed connection between the clamp body 1811 and the first crimping ring 1812, and also isolates the first crimping ring 1812 from the coolant to prevent the coolant from penetrating into the optical fiber 1822 inside the optical cable body 182 through the reinforcing wire 1823. The ninth sealing member blocks the gap between the optical cable body 182 and the second crimping ring 1813 to ensure the sealed connection between the second crimping ring 1813 and the optical cable body 182.

[0240] In some embodiments, the sixth sealing glue is soft glue. For example, the fifth sealing glue is silicone.

[0241] The optical cable fixing member 181 also includes a protective sleeve 1814, which is covered on the eighth sealing member, the second crimping ring 1813 and the cable skin 1821 to protect the optical cable body 182. The height of the eighth sealing member shall not exceed the height of the second crimping ring 1813 to prevent the protective sleeve 1814 from being unable to push down 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 is evenly covered on the first crimping ring 1812 to further prevent the reinforcement wire 1823 from being exposed to the coolant; the ninth sealing member is evenly covered on the gap between the optical cable body 182 and the second crimping ring 1813 to further ensure the sealed connection between the second crimping ring 1813 and the optical cable body 182.

A reinforcing wire is arranged between the first crimping ring and the clamp to crimp the reinforcing wire onto the clamp. The reinforcing wire shall not exceed the left end of the first crimping ring to reduce the cooling liquid outside the optical module from penetrating into the optical fiber inside the optical cable body through the reinforcing wire.

[0254] The isolation sleeve 1831 includes a first inner plug block and a second inner plug block, which are of the same shape and connected to form an isolation sleeve 1831 having a second cavity and two first through holes 1837. Apply the seventh sealing glue to the bottom of the first inner plug block, install the cut optical cable body inside the first inner plug block, and then apply a layer of the seventh sealing glue to completely block the cut ends of the cut optical cable body; cover the second inner plug block, and fix the first and second inner plug blocks with masking tape; place the fixed first and second inner plug blocks at a high temperature of 100°C for more than 1 hour, and wait for the seventh sealing glue to solidify to form the tenth sealing member.

[0255] In some embodiments, the isolation member 183 further includes a protective tail tube 1833 and a protective tail tube 1834, which are respectively covered at both ends of the isolation sleeve 1831 to protect the optical cable body. After the seventh sealing glue in the isolation sleeve 1831 is cured to form the tenth sealing member, the protective tail tubes 1833 are respectively put on at both ends of the isolation sleeve 1831.

[0256] The protective tail tube 1833 is provided with a third through hole 1839 , and the third through hole 1839 is arranged corresponding to the first through hole 1837 to prevent the optical cable body 182 from passing through the first through hole 1837 and the third through hole 1839 .

[0257] The protective tail tube 1833 and the protective tail tube 1834 both include a clamping end and a protective end, one end of the clamping end is covered at both ends of the isolation sleeve 1831, 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 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.

[0258] 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 .

[0259] In some embodiments, the isolation member 183 further includes a heat shrinkable tube, which is sleeved on the isolation tube 1831 to ensure the stability of the isolation tube 1831. After the seventh sealing glue in the isolation tube 1831 is cured to form the tenth sealing member, the heat shrinkable tube is covered on the isolation tube 1831, and the heat shrinkable tube is heated by a heater to shrink it and then clamp it on the isolation tube 1831, thereby improving the stability of the isolation tube 1831.

[0260] However, since the isolation sleeve 1831 is composed of the first inner block and the 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, which can easily cause the isolation sleeve 1831 to break at the connection between the first inner block and the second inner block.

The protective sleeve 1832 is covered on the isolation sleeve 1831 to ensure the strength of the isolation sleeve 1831. The two protective tail tubes 1833 are respectively covered at both ends of the protective sleeve 1832 to protect the optical cable body 182.

[0262] Second through holes 1838 are provided at both ends of the protective sleeve 1832 , and the second through holes 1838 are correspondingly arranged with the first through holes 1837 and the third through holes 1839 to avoid the optical cable body 1822 , so that the optical cable body 182 passes through the first through holes 1837 , the second through holes 1838 and the third through holes 1839 .

[0263] Two limiting protrusions 1835 are arranged on the outside of the protective sleeve 1832, and the two limiting protrusions 1835 are respectively located at the two ends of the protective sleeve 1832.

A third cavity is arranged on the inside of the protective sleeve 1832, and an isolation sleeve 1831 and an eleventh sealing member are arranged in the third cavity. 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 realizing the stable connection between the isolation sleeve 1831 and the protective sleeve 1832, and the sealed connection between the protective sleeve 1832 and the optical cable body 182.

[0264] In some embodiments, a limiting step 1836 is provided in the third cavity inside the protective sleeve 1832, and the limiting step 1836 is used to limit the position of the isolation sleeve 1831 in the protective sleeve 1832. By way of 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 in the protective sleeve 1832. By way of 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 in the protective sleeve 1832.

[0265] In some embodiments, an eleventh seal is provided in the area of ​​the third cavity except the isolation sleeve 1831. The eleventh seal is located between the limiting step 1836 and the inner 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.

[0266] The protective sleeve 1832 is a hollow cylinder (with a third cavity arranged inside). After the seventh sealing glue in the isolation sleeve 1831 is cured to form the tenth sealing member, the seventh sealing glue is applied to the outer side of the isolation sleeve 1831 and inserted into the protective sleeve 1832.

Wait for the seventh sealing glue to cure to form the eleventh sealing member. After the seventh sealing glue in the protective sleeve 1832 is cured to form the eleventh sealing member, the protective tail pipe 1833 is respectively put on the two ends of the protective sleeve 1832.

[0267] In some embodiments, the seventh sealant is a hard glue, for example, the seventh sealant is a hot melt glue. The epoxy system sealant is also a hard glue, but the seventh sealant has a lower hardness than the epoxy system sealant, and has a higher hardness than the fifth and sixth sealants.
