[0055] In optical communication technology, in order to establish information transmission between information processing devices, information needs to be loaded onto light, and the transmission of information is achieved by the propagation of light. Here, the light loaded with information is an optical signal. The optical signal can reduce the loss of optical power when transmitted in an information transmission device, so that high-speed, long-distance, low-cost information transmission can be achieved. The signal that can be recognized and processed by the information processing device is an electrical signal. The information processing device usually includes an optical network unit (ONU), a gateway, a router, a switch, a mobile phone, a computer, a server, a tablet computer, a television, etc., and the information transmission device usually includes an optical fiber and an optical waveguide, etc.

[0056] An optical module can realize the mutual conversion between the optical signal and the electrical signal between the information processing device and the information transmission device. For example, at least one of the optical signal input end or the optical signal output end of the optical module is connected with 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 with an optical network unit; a first optical signal from the optical fiber is transmitted to the optical module, the optical module converts the first optical signal into a first electrical signal, and transmits the first electrical signal to the optical network unit; a second electrical signal from the optical network unit is transmitted to the optical module, 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 with the optical module, without the need for all the information processing devices to be directly connected with the optical module. Here, the information processing device directly connected with the optical module is referred to as the host computer of the optical module. In addition, the optical signal input end or the optical signal output end of the optical module can be referred to as an optical port, and the electrical signal input end or the electrical signal output end of the optical module can be referred to as an electrical port.

[0057] Figure 1 A partial architecture diagram of an optical communication system according to some embodiments. As shown in FIG. 1, the optical communication system includes an optical network unit (ONU) 100, a gateway 200, a router 300, a switch 400, a mobile phone 500, a computer 600, a server 700, a tablet computer 800, a television 900, an optical module 10, an optical fiber 20, and an optical waveguide 30. Figure 1As shown, the optical communication system mainly comprises 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.

[0058] One end of the optical fiber 101 extends towards 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 maintain the original optical power. The optical signal is totally reflected multiple times 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 and low-power-loss information transmission.

[0059] The optical communication system can comprise one or more optical fibers 101, and the optical fiber 101 is detachably connected or fixedly connected to the optical module 200. The host computer 100 is configured to provide a data signal to the optical module 200, or receive a data signal from the optical module 200, or monitor or control the working state of the optical module 200.

[0060] The host computer 100 comprises a housing substantially in the shape of a cuboid, and an optical module interface 102 disposed on the housing. The optical module interface 102 is configured to access the optical module 200 to establish a unidirectional or bidirectional electrical signal connection between the host computer 100 and the optical module 200.

[0061] The host computer 100 also includes an external electrical interface that can access an electrical signal network. For example, the external electrical interface includes a Universal Serial Bus (USB) interface or a network cable interface 104. The network cable interface 104 is configured to access a network cable 103 so that the host computer 100 establishes a unidirectional or bidirectional electrical signal connection with the network cable 103. One end of the network cable 103 is connected to the local information processing device 2000, and the other end of the network cable 103 is connected to the host computer 100, so that an electrical signal connection is established between the local information processing device 2000 and the host computer 100 via the network cable 103. For example, a third electrical signal emitted by the local information processing device 2000 is transmitted to the host computer 100 via the network cable 103. The host computer 100 generates a second electrical signal based on the third electrical signal. The second electrical signal from the host computer 100 is transmitted to the optical module 200. The optical module 200 converts the second electrical signal into a second optical signal and transmits the second optical signal to the optical fiber 101. The second optical signal is then transmitted to the remote information processing device 1000 via the optical fiber 101. For example, a first optical signal from the remote information processing device 1000 is transmitted through the optical fiber 101. The first optical signal from the optical fiber 101 is transmitted to the optical module 200. The optical module 200 converts the first optical signal into a first electrical signal. The optical module 200 transmits the first electrical signal to the host computer 100. The host computer 100 generates a fourth electrical signal based on the first electrical signal and transmits the fourth electrical signal to the local information processing device 2000. It should be noted that optical modules are tools for converting optical signals into electrical signals. During this conversion process, the information does not change, but the encoding and decoding methods of the information can change.

[0062] 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.

[0063] Figure 2 FIG1 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 105 disposed within the housing, a cage 106 disposed on the surface of the PCB 105, a heat sink 107 disposed on the cage 106, and an electrical connector disposed within the cage 106. The electrical connector is configured to connect to the electrical port of the optical module 200; the heat sink 107 has protruding structures such as fins to increase the heat dissipation area.

[0064] The optical module 200 is inserted into the cage 106 of the host computer 100, and the optical module 200 is fixed by the cage 106. The heat generated by the optical module 200 is conducted 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 and the host computer 100 establish a bidirectional electrical signal connection. In addition, the optical port of the optical module 200 is connected to the optical fiber 101, so that the optical module 200 and the optical fiber 101 establish a bidirectional optical signal connection.

[0065] Figure 3 A structural diagram of an optical module according to some embodiments. Figure 4 An exploded view of an optical module according to some embodiments. As shown in Figure 3 and Figure 4 The optical module 200 includes a shell, a circuit board 300 arranged in the shell, and an optical transceiver component 900.

[0066] The shell includes an upper shell 201 and a lower shell 202. The upper shell 201 is covered on the lower shell 202 to form the above-mentioned shell with two openings 204 and 205. The outer contour of the shell generally presents a square body.

[0067] In some embodiments, the lower shell 202 includes a bottom plate 2021 and two lower side plates 2022 arranged perpendicularly to the bottom plate 2021 on both sides of the bottom plate 2021. The upper shell 201 includes a cover plate 2011, which is covered on the two lower side plates 2022 of the lower shell 202 to form the above-mentioned shell.

[0068] In some embodiments, the lower shell 202 includes a bottom plate 2021 and two lower side plates 2022 arranged perpendicularly to the bottom plate 2021 on both sides of the bottom plate 2021. The upper shell 201 includes a cover plate 2011 and two upper side plates arranged perpendicularly to the cover plate 2011 on both sides of the cover plate 2011. The two upper side plates are combined with the two lower side plates 2022 to realize that the upper shell 201 is covered on the lower shell 202.

[0069] The direction of the line connecting the two openings 204 and 205 can be consistent with the length direction of the optical module 200, or can be inconsistent with the length direction of the optical module 200. For example, the opening 204 is located at the end (right end) of the optical module 200, and the opening 205 is also located at the end (left end) of the optical module 200. Figure 3 Figure 3 ​Or, 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 fingers of the circuit board 300 extend from the electrical port and are inserted into the electrical connector of the host computer 100; the opening 205 is an optical port and 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.

[0070] The upper shell 201 and the lower shell 202 are combined to facilitate the installation of the circuit board 300 and the optical transceiver component 900 into the shells, and the shells can encapsulate and protect the devices. In addition, when the circuit board 300 and the optical transceiver component 900 are assembled, the positioning components, heat dissipation components, and electromagnetic shielding components of these devices can be easily arranged, which facilitates the automated production.

[0071] In some embodiments, the upper shell 201 and the lower shell 202 are made of metal materials, which facilitates electromagnetic shielding and heat dissipation.

[0072] In some embodiments, the optical module 200 further includes an unlocking component 600 located outside the shell of the optical module 200. The unlocking component 600 is configured to achieve the 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.

[0073] For example, the unlocking component 600 is located outside the two lower side plates 2022 of the lower shell 202 and includes a clamping component that matches the cage 106 of the host computer 100. When the optical module 200 is inserted into the cage 106, the clamping component of the unlocking component 600 fixes the optical module 200 in the cage 106. When the unlocking component 600 is pulled, the clamping component of the unlocking component 600 moves, thereby changing the connection relationship between the clamping component and the host computer, releasing the fixation between the optical module 200 and the host computer, and allowing the optical module 200 to be pulled out of the cage 106.

[0074] The circuit board 300 includes circuit traces, electronic components, and chips. The electronic components and chips are connected according to the circuit design through the circuit traces to achieve functions such as power supply, electrical signal transmission, and grounding. Electronic components may include, for example, capacitors, resistors, transistors, and metal-oxide-semiconductor field-effect transistors (MOSFETs). Chips may include, for example, microcontroller units (MCUs), laser driver chips, transimpedance amplifiers (TIAs), limiting amplifiers, clock and data recovery chips (CDRs), power management chips, and digital signal processing (DSP) chips.

[0075] 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.

[0076] The circuit board 300 also includes a gold finger formed on its end surface. 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 gold fingers are configured to establish an electrical connection with the host computer to facilitate power supply, grounding, two-wire synchronous serial (I2C) signal transmission, and data signal transmission. Of course, some optical modules also use flexible circuit boards. These are generally used in conjunction with rigid circuit boards to supplement them.

[0077] 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.

[0078] 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 staggered, and the optical transceiver component 900 has both transmitting and receiving functions to realize two groups of optical transmitting and two groups of optical receiving.

[0079] In some embodiments, the optical transceiver component 900 includes one first optical transceiver component and one second optical transceiver component staggered, or one first optical transceiver component and one third optical transceiver component staggered, or one second optical transceiver component and one third optical transceiver component staggered, and the optical transceiver component 900 has both transmitting and receiving functions to realize two groups of optical transmitting and two groups of optical receiving.

[0080] Figure 5 A cross-sectional view of the optical transceiver component and the circuit board according to some embodiments is provided. Figure 6 An exploded view of the optical transceiver component and the circuit board according to some embodiments is provided. Figure 5 And Figure 6 As shown in FIGS. 3 and 4, 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 laser drive chip 3021 and / or a TIA chip 3022, etc. The optical matching chip 302 is adhered to the circuit board 300 by silver glue, which plays a role in fixing and heat dissipation, and then the circuit connection between the optical matching chip 302 and the circuit board 300 is realized by gold wire bonding. The optical chip 303 can be an optical transmitting chip 3031 and / or an optical receiving chip 3032. The optical transmitting chip 3031 and the optical receiving chip 3032 can be fixed side by side on the circuit board 300.

[0081] In some embodiments, the optical transceiver component 900 includes a fiber holder and a lens assembly. The fiber holder is optically connected with the lens assembly. The lens assembly covers the optical matching chip 302 and the optical chip 303 on the circuit board 300, so as to place the optical matching chip 302 and the optical chip 303 in a covering cavity formed by the lens assembly and the circuit board.

[0082] Since the optical chip 303 is attached to the circuit board 300, the light emitting surface or the light entering surface is located at the top surface of the optical chip 303. Thus, 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 also perpendicular to the circuit board 300. The optical fiber 101 connected with the optical module is parallel to the circuit board 300. Therefore, the transmission direction of the light beam emitted by the optical transmitting chip and the external light beam transmitted to the optical receiving chip needs to be changed. Thus, the lens assembly is used to change the light beam emitted by the optical transmitting chip, so that the light beam emitted by the optical transmitting chip is reflected by the lens assembly, 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 received light beam transmitted by the external optical fiber is reflected by the lens assembly, and the reflected light beam is perpendicular to the circuit board 300, so as to facilitate the reception by the optical receiving chip.

[0083] As shown in Figure 6 The circuit board 300 is also provided with a DSP chip 301 for processing high-frequency signals. The high-frequency signals received by the light receiving chip 3032 are amplified by the TIA chip 3022 and transmitted to the DSP chip 301 via the high-frequency signal line connecting the TIA chip 3022 and the DSP chip 301 for processing, and then transmitted to the communication system via the gold finger. The transmitting end is just the opposite, the signal received at the gold finger is processed by the DSP chip 301, the processed signal is transmitted to the laser drive chip 3021 via the signal line connecting the DSP chip 301 and the laser drive chip 3021, and then transmitted to the light emitting chip 3031 to convert into optical signals, and the optical signals emitted by the light emitting chip 3031 are coupled into the optical fiber through the lens assembly of the optical transceiver component 900 for transmission.

[0084] With the increase of communication rate, although the power consumption per unit bandwidth is decreasing, the overall power consumption of the optical module is further increasing, and the heat dissipation mode adopted in the client device is mostly air cooling. For high-speed transmission systems, the heat dissipation capacity has reached the limit. In order to get rid of the predicament of air cooling, people began to study various liquid cooling methods, one of which is to immerse the switch into a refrigerant such as fluorinated liquid (FC-40). However, due to the low cost requirement, the optical transmitting component and the optical receiving component of the optical module deployed in the data center are mostly designed in a non-sealed structure, and the key optical paths are 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, thereby causing changes in the optical mechanism and contamination of the optical surface, which seriously affects the normal work of the optical module.

[0085] In some embodiments, in order to prevent the cooling liquid from entering 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, a first sealing member is arranged between the lens assembly and the circuit board 300 after the lens assembly is covered on the optical chip 303 and the optical matching chip 302. The first sealing member is located on the outer side wall of the lens assembly and the surface of the circuit board 300, that is, the sealing glue is added to the periphery of the contact between the lens assembly and the circuit board 300, so that the sealing glue completely seals the gap between the lens assembly and the circuit board 300, and the sealing glue has a pile on the surface of the circuit board 300 and the outer side wall of the lens assembly. After the sealing glue solidifies, the first sealing member is formed. For example, the lens assembly can be a first lens assembly, a first sealing member is arranged between the first lens assembly and the circuit board 300; the lens assembly can be a second lens assembly, a first sealing member is arranged between the second lens assembly and the circuit board 300; the lens assembly can be a third lens assembly, a first sealing member is arranged between the third lens assembly and the circuit board 300.

[0086] In some embodiments, the sealing glue is an epoxy-based glue. The epoxy-based sealing glue has excellent chemical corrosion resistance, heat resistance and bonding performance, and can better prevent the cooling liquid from seeping in.

[0087] The epoxy-based sealing glue can be the first sealing glue, the second sealing glue, the third sealing glue or the fourth sealing glue. The bonding force of the first sealing glue, the third sealing glue and the fourth sealing glue is greater than that of the second sealing glue. The viscosity of the first sealing glue is greater than that of the third sealing glue, and the viscosity of the first sealing glue is greater than that of the fourth sealing glue. The viscosity of the third sealing glue is less than that of the fourth sealing glue.

[0088] In some embodiments, in order to prevent the cooling liquid from seeping into the optical path between the lens assembly and the fiber support through the gap between the lens assembly and the fiber support, a second sealing member is arranged between the fiber support and the lens assembly after the fiber support is inserted into the lens assembly.

[0089] For example, the lens assembly is provided with a clamping groove, and the fiber support is placed in the clamping groove, that is, three sides of the clamping groove are respectively arranged corresponding to the corresponding sides of the fiber support, and a clamping surface of the clamping groove is arranged corresponding to a first end surface of the fiber support. After the fiber support is placed in the clamping groove, the first sealing glue is injected at the gap between the clamping groove and the fiber support (including the gap between the three sides of the clamping groove and the sides of the fiber support and the gap between the clamping surface of the clamping groove and the first end surface of the fiber support), and a sealing member is formed after the first sealing glue is cured to prevent the cooling liquid from seeping in through the gap between the fiber support and the clamping groove.

[0090] However, the first sealing glue may seep into the first end surface of the fiber support and then into the optical path between the lens assembly and the fiber support through the gap between the clamping surface of the clamping groove and the first end surface of the fiber support (the surface of the fiber support facing the lens assembly), which affects the total optical path of the optical transceiver component.

[0091] To solve this problem, a shielding member is arranged to shield the gap between the lens assembly and the first end of the fiber support. The first sealing glue is injected at the outer side wall of the shielding member, so that the first end surface of the fiber support is far away from the position where the first sealing glue is located, and thus the first end surface of the fiber support is not easily contaminated by the first sealing glue.

[0092] In some embodiments, the shielding member is integrally formed with other structures of the lens assembly, the shielding member and the clamping groove form a wrapping cavity, and the shielding member is a side wall of the wrapping cavity away from the circuit board.

[0093] 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 is covered on the optical fiber bracket, and the other end of the sealing cover plate is covered on the optical port groove.

[0094] Figure 7 This is a structural diagram of a first optical transceiver component provided according to some embodiments. Figure 8 This is an exploded view of a first optical transceiver component provided according to some embodiments. Figure 9 FIG. 1 is a cross-sectional view of a first optical transceiver component according to some embodiments. Figure 7 、 Figure 8 and Figure 9 As shown, in some embodiments, the first optical transceiver component 901 includes a first lens assembly 911 and an optical fiber holder 912. A wrapping cavity 9112 is provided at one end of the first lens assembly 911, and an opening is provided on one side of the wrapping cavity 9112. An optical fiber 9127 is fixed to one end of the optical fiber holder 912. The optical fiber holder 912 carries the optical fiber 9127 and is inserted into the wrapping cavity 9112 through the opening to achieve a connection between the optical fiber holder 912 and the first lens assembly 911. After the optical fiber holder 912 is inserted into the wrapping cavity 9112, the wrapping cavity 9112 wraps the optical fiber holder 912, and the first end face of the optical fiber holder 912 is buried in the wrapping cavity 9112. A first sealing glue is applied to the glue dispensing surface 91124 of the wrapping cavity 9112, so that the first end face of the optical fiber holder 912 is far away from the location of the first sealing glue, thereby preventing the first end face of the optical fiber holder 912 from being contaminated by the first sealing glue. After the first sealant cures, a second sealant is formed. The second sealant is located on the side of the optical fiber holder 912 and around the adhesive dispensing surface 91124 of the wrapping cavity 9112 to isolate the coolant. Specifically, after the optical fiber holder 912 is inserted into the wrapping cavity 9112, the first sealant is applied to the adhesive 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 holder 912. The first sealant accumulates between the wrapping cavity 9112 and the optical fiber holder 912. In this way, after the first sealant cures, a second sealant is formed to ensure the tight connection between the first lens assembly 911 and the optical fiber holder 912, thereby preventing the infiltration of coolant.

[0095] After the optical fiber holder 912 is inserted into the wrapping cavity 9112, the four side surfaces of the optical fiber holder 912 are respectively arranged corresponding to the four side walls corresponding to the wrapping cavity 9112, and the first end face of the optical fiber holder 912 is arranged corresponding to the clamping wall of the wrapping cavity 9112. The clamping wall of the wrapping cavity 9112 is located deep in the wrapping cavity 9112, away from the glue spot surface 91124 of the wrapping cavity 9112, that is, the first end face of the optical fiber holder 912 is located in the wrapping cavity 9112, away from the glue spot surface 91124 of the wrapping cavity 9112.

[0096] The first lens assembly 911 is provided in the package cavity 9112 and corresponds to the optical fiber support 912. The first lens assembly 911 includes a receiving collimating lens and a transmitting coupling lens. The transmitting 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 support 912.

[0097] When the first lens assembly 911 is coupled and attached to the circuit board 300, a suction nozzle is needed 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 the optical chip on the circuit board 300 is coupled. If the upper surface of the first lens assembly 911 is not flat or does not have a large enough flat surface, the upper surface of the first lens assembly 911 has no place to place the suction nozzle. Therefore, a large suction flat surface is needed to be provided on the upper surface of the first lens assembly 911 to place the suction nozzle so that the suction nozzle sucks the first lens assembly 911. In some embodiments, the top surface of the area of the first lens assembly 911 corresponding to the package cavity 9112 is flush with the top surface of the area of the first lens assembly 911 other than the package cavity 9112, which provides a large suction flat surface for the suction nozzle to suck the first lens assembly 911.

[0098] As shown in Figure 7 , Figure 8 and Figure 9 , the first lens assembly 911 is provided with an optical port groove 9111 on the area other than the package cavity 9112. The top surface (the surface away from the circuit board 300) of the optical port groove 9111 is provided with an opening, and the other end of the groove wall of the optical port groove 9111 is formed with a reflecting surface 9115, which is provided opposite to the first lens 9116. In this way, the light signal emitted by the optical chip 303 (specifically the light emitting chip 3031) is reflected by the reflecting surface 9115, and the reflected light beam is emitted through the first lens 9116. The light beam transmitted by the optical fiber and received by the first lens 9116 is reflected by the reflecting surface 9115, and the reflected light signal is incident on the optical chip 303 (specifically the light receiving chip 3032).

[0099] The wrapping cavity 9112 wraps the various sides of the fiber support 912, and increases the thickness of the right side of the first lens assembly 911 (i.e., the end connected to the fiber support 912). If the thickness of the left side of the first lens assembly 911 (i.e., the end not connected to the fiber support 912) is not increased, the thickness ratio of the first lens assembly 911 will be greatly different. Therefore, the thickness of the left side of the first lens assembly 911 needs to be increased, i.e., the thickness of the region 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) needs to be increased. The thickness of the region of the first lens assembly 911 other than the wrapping cavity 9112 is increased, but the height of the position where the first lens 9116 is mounted is not changed. In order for the reflecting surface 9115 to reflect the optical signal to the first lens 9116, in some embodiments, the depth of the optical port groove 9111 is increased. The depth of the optical port groove 9111 is increased, the distance between the opening of the optical port groove 9111 and the reflecting surface 9115 is increased, and the penetration of the seal into the reflecting surface 9115 through the opening of the optical port groove 9111 is reduced.

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

[0101] In order to prevent the cooling liquid from penetrating into the reflecting surface 9115, in some embodiments, one end of the groove wall of the optical port groove 9111 is provided with a glue isolation protrusion, and a large number of third seals are arranged on the glue isolation protrusion. The glue isolation protrusion narrows the optical port groove 9111 and forms a deep well groove. The opening of the optical port groove 9111 is injected with first sealant to block the opening of the optical port groove 9111, and the reflecting surface of the optical port groove 9111 is isolated from the external cooling liquid to prevent the cooling liquid from penetrating into the reflecting surface of the optical port groove 9111. Because the first sealant is thick, the first sealant can only cover the upper part of the deep well groove (i.e., the glue isolation protrusion of the optical port groove 9111), and the air in the lower part of the deep well groove supports the first sealant, so that the first sealant cannot flow down onto the reflecting surface 9115, thereby ensuring that the reflecting surface 9115 is isolated from the external cooling liquid and is not affected by the first sealant.

[0102] The top surface of the light port groove 9111 is provided with an opening to facilitate the demolding process of the plastic mold. In order to prevent the cooling liquid from seeping into the reflecting surface 9115 through the opening of the light port groove 9111, in some embodiments, a blocking component is arranged on the top surface of the opening of the light port groove 9111 and fixed to the top surface of the light port groove 9111 to seal the opening of the light port groove 9111, thereby preventing the cooling liquid from seeping in through the opening of the light port groove 9111.

[0103] In some embodiments, the blocking component includes a sealing cover plate, one end of the sealing cover plate is covered on the fiber support, and the other end of the sealing cover plate is covered on the light port groove to seal the opening of the light port groove 9111.

[0104] In some embodiments, the blocking component includes a baffle 913 fixed to the top surface of the light port groove 9111 to seal the opening of the light port groove 9111.

[0105] In some embodiments, the baffle 913 is coated with an adhesive on the side surface thereof towards the light port groove 9111, and the baffle 913 is adhered to the top surface of the light port groove 9111 by the adhesive to achieve the fixation of the baffle 913 to the top surface of the light port groove 9111.

[0106] In some embodiments, the material of the baffle 913 can be selected from, but not limited to, polyimide.

[0107] The size of the baffle 913 is greater than the size of the opening of the light port groove 9111, so that the baffle 913 can completely block the opening of the light port groove 9111. After the opening of the light port groove 9111 is sealed by the baffle 913, a first sealing glue can be further added to the side surface of the baffle 913, i.e., the first sealing glue is added to the connection between the baffle 913 and the surface of the first lens assembly 911, and after the first sealing glue is cured, a third sealing member is formed to seal the baffle 913 and the opening of the light port groove 9111, so as to reduce the seepage of the cooling liquid into the light port groove 9111 and ensure that the light port groove 9111 is isolated from the cooling liquid.

[0108] However, the baffle 913 and the opening of the light port groove 9111 are only connected by the back adhesive, and the adhesive force of the back adhesive is not enough, which leads to poor connection stability between the baffle 913 and the opening of the light port groove 9111, and further leads to poor connection sealing between the baffle 913 and the opening of the light port groove 9111, that is, the opening of the baffle 913 and the light port groove 9111 cannot be completely sealed. In order to completely seal the opening of the baffle 913 and the light port groove 9111, in some embodiments, the first sealing glue is added above and around the baffle 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, the third sealing member is formed, which completely seals the opening of the baffle 913 and the light port groove 9111, further reduces the penetration of the cooling liquid into the light port groove 9111, and further ensures that the light port groove 9111 is isolated from the cooling liquid.

[0109] Since the first sealing glue can move, the movement of the first sealing glue easily leads to that the third sealing member after the first sealing glue is cured cannot completely seal the opening of the baffle 913 and the light port groove 9111. In order to solve this problem, in some embodiments, a storage groove is arranged outside the light port groove 9111, the light port groove 9111, the baffle 913 and the third sealing member are arranged in the storage groove, and the third sealing member is located at the top and the outer side wall of the baffle 913. The first sealing glue is injected into the storage groove to wrap 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. After the first sealing glue is cured, the third sealing member is formed. The third sealing member is located at the top and the outer side wall of the baffle 913 to stably connect the baffle 913 and the storage groove. The storage groove can limit the third sealing member in a predetermined position to avoid the third sealing member deviating from the predetermined position, so as to completely seal the opening of the baffle 913 and the light port groove 9111, and further ensure that the light port groove 9111 is isolated from the cooling liquid.

[0110] In some embodiments, a storage groove is arranged outside the light port groove 9111, the light port groove 9111, the baffle 913 and the third sealing member are arranged in the storage groove, and a glue isolation protrusion is arranged at one end of the groove wall of the light port groove 9111. The storage groove can fix the third sealing member in a predetermined position to completely seal the opening of the baffle 913 and avoid the penetration of the cooling liquid. The first sealing glue in the storage groove penetrates into the glue isolation protrusion of the light port groove 9111, and the first sealing glue wraps the glue isolation protrusion. 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 cooling liquid and is not affected by the first sealing glue.

[0111] In some embodiments, the outer side of the light port groove 9111 is provided with a storage groove, the storage groove is provided with the light port groove 9111, the baffle 913 and the third sealing element, one end of the groove wall of the light port groove 9111 is provided with a glue isolation protrusion, and a large number of third sealing elements are arranged on the glue isolation protrusion. The storage groove can fix the third sealing element in a preset position to realize complete sealing of the baffle 913 and the opening, so as to avoid the infiltration of the cooling liquid; the first sealing glue in the storage groove infiltrates the first sealing glue of the light port groove 9111, the first sealing glue of the light port groove 9111 is wrapped on the glue 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 to the reflecting surface 9115, thereby ensuring that the reflecting surface 9115 is isolated from the external cooling liquid and is not affected by the first sealing glue.

[0112] In some embodiments, the optical module includes two groups of optical transceiver components arranged in staggered manner, when the placement positions of the two optical transceiver components are too close, the optical fiber connected to one optical transceiver component needs to cross the other optical transceiver component, which easily causes the bending radius of the optical fiber to be too small, affecting the transmission of the optical fiber. In order to solve this problem, the first lens assembly 911 is provided with an inclined surface 9113, which is inclined downward along the top surface of the first lens assembly 911 away from the side surface of the first lens assembly 911 away from the optical fiber support 912, that is, the inclined surface 9113 is an inclined downward inclined surface. The rear optical fiber is inclined upward along the inclined surface 9113, so that the optical fiber has a larger bending radius, avoiding the problem of optical fiber transmission caused by the too small radius of the optical fiber.

[0113] As shown in Figure 9 The side of the first lens assembly 911 facing the circuit board 300 is provided with a cover cavity 9124, the cover cavity 9124 is recessed from the bottom surface to the top surface of the first lens assembly 911, so that when the first lens assembly 911 is sealed and installed with the circuit board 300, the cover cavity 9124 forms a sealed cavity, and the optoelectronic devices such as the optical chip 303 and the optical matching chip 302 are located in the sealed cavity, which can prevent the cooling liquid from infiltrating into the first lens assembly 911 to cause the failure of the optoelectronic devices such as the optical chip 303 and the optical matching chip 302.

[0114] The inner side wall of the cover cavity 9124 is provided with a second lens 9117, which is located below the reflecting surface 9115, and the light chip 303 is located below the second lens 9117. The second lens 9117 can be a transmitting collimating lens, and the light chip 303 is a light emitting chip. In this way, the light beam emitted by the light emitting chip is converted into a collimated light beam through the transmitting collimating lens, the collimated light beam is reflected by the reflecting surface 9115, and the reflected collimated light beam is converted into a converging light beam through the first lens 9116 and coupled to the optical fiber. The second lens can also be a receiving coupling lens, and the light chip 303 is a light receiving chip. In this way, the receiving light beam is reflected by the reflecting surface 9115 through the first lens 9116, and the reflected receiving light beam is coupled to the light receiving chip through the receiving coupling lens.

[0115] After the first sealant 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 sealant seals the gap between the wrapping cavity 9112 and the optical fiber support 912, the optical module also needs to be placed in a high-temperature environment. The air in the cavity sealed by the first sealant will expand at high temperature. If there is no release hole, the expanded air will push the unhardened first sealant out of an air hole, causing the cooling liquid to seep in. Therefore, the first lens assembly 911 is also provided with a gas permeable hole 9119, which is in communication with the cover cavity 9124 or the wrapping cavity 9112. The air in the cover cavity 9124 or the wrapping cavity 9112 expands and is released through the gas permeable hole 9119. The gas permeable hole 9119 is filled with the second sealant, and after the second sealant is hardened to form the twelfth sealing member, the twelfth sealing member blocks the gas permeable hole 9119 to prevent the cooling liquid from seeping into the first lens assembly 911 through the gas permeable hole 9119.

[0116] Figure 10 An assembly view of the first lens assembly and the baffle according to some embodiments is provided. Figure 11 An exploded view of the first lens assembly and the baffle according to some embodiments is provided. Figure 12 A structural view of the first lens assembly from a first perspective according to some embodiments is provided. As shown in FIG. 11A, the first lens assembly 911 is provided with a first lens 9111, a second lens 9117, a third lens 9118, a fourth lens 9114, a fifth lens 9113, a sixth lens 9110, a seventh lens 9112, an eighth lens 9111, a ninth lens 9116, a tenth lens 9115, an eleventh lens 9112, and a twelfth lens 9113. Figure 10 Figure 11 Figure 12 ​​As shown, in some embodiments, the placement groove includes a first placement groove 9120, the first placement groove 9120 is provided with a baffle 913 and a third sealing member, the third sealing member is located on the top and the outer side wall of the baffle 913. After the baffle 913 is attached to the first placement groove 9120, the first sealing glue is filled in the first placement 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 solidified. The first placement groove 9120 limits the position of the third sealing member on the surface of the first lens assembly 911, avoids the third sealing member deviating from the preset position, and realizes the stable connection of the baffle 913 and the opening of the light port groove 9111.

[0117] The depth size of the first placement groove 9120 and the height size of the third sealing member are both greater than the thickness size of the baffle 913, the length size of the first placement groove 9120 is greater than the length size of the baffle 913, or the width size of the first placement groove 9120 is greater than the width size of the baffle 913, so that the third sealing member is located on the top and the outer side wall of the baffle 913.

[0118] In some embodiments, the placement groove further includes a second placement groove 9121, the second placement groove 9121 is formed by inwardly recessing the first placement groove 9120, the third sealing member is placed in the first placement groove 9120 and the second placement groove 9121, and the baffle 913 is placed in the second placement groove 9121, the third sealing member is located on the top and the outer side wall of the baffle 913. After the baffle 913 is attached to the second placement groove 9121, the first sealing glue is filled in the first placement groove 9120, 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 solidified. The second placement groove 9121 limits the position of the baffle 913 on the surface of the first lens assembly 911, avoids the baffle 913 deviating from the preset position, and makes the baffle 913 completely cover the opening of the light port groove 9111, thereby realizing the stable connection of the baffle 913 and the second placement groove 9121.

[0119] The length size of the second placement groove 9121 is greater than the length size of the baffle 913, or the width size of the second placement groove 9121 is greater than the width size of the baffle 913, so that the baffle 913 and the third sealing member are placed in the second placement groove 9121. After the baffle 913 is attached to the second placement groove 9121, the first sealing glue is injected between the baffle 913 and the second placement groove 9121, and the first placement groove 9120 is filled with the first sealing glue, 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 solidified.

[0120] As Figure 10 , Figure 11 and Figure 12As shown, in some embodiments, the first sealant protrusion 9122 is formed by the wall of the light port groove 9111, the first sealant protrusion 9122 narrows the light port groove 9111, forming a deep well groove. Since the first sealant is viscous, it can only coat the upper part of the first sealant protrusion 9122 in the deep well groove, and the lower part of the deep well groove supports the first sealant, preventing the first sealant from flowing onto the reflecting surface 9115, thereby ensuring that the reflecting surface 9115 is isolated from the external cooling liquid and is not affected by the first sealant.

[0121] In some embodiments, the first sealant protrusion 9122 is formed by the wall of the light port groove 9111, the first sealant protrusion 9122 is a non-closed annular protrusion, and the non-closed annular protrusion and the opening of the light port groove 9111 form a first step.

[0122] In some embodiments, the first sealant protrusion 9122 is formed by the wall of the light port groove 9111, the first sealant protrusion 9122 is a non-closed annular protrusion, and the non-closed annular protrusion and the opening of the light port groove 9111 form a first step.

[0123] In some embodiments, the first sealant protrusion 9122 is formed by the wall of the light port groove 9111, the first sealant protrusion 9122 is a non-closed annular protrusion, and the non-closed annular protrusion and the opening of the light port groove 9111 form a first step.

[0124] Similarly, the closed annular protrusion of the same width narrows the size of the light port groove 9111, and the capacity of the first sealant that can be carried increases, so the reflecting surface of the first lens assembly 911 with the closed annular protrusion is less likely to be affected by the external cooling liquid and the first sealant than the first lens assembly 911 with the non-closed annular protrusion.

[0125] Similarly, the closed annular protrusion of the same width narrows the size of the light port groove 9111, and the capacity of the first sealant that can be carried increases, so the reflecting surface of the first lens assembly 911 with the closed annular protrusion is less likely to be affected by the external cooling liquid and the first sealant than the first lens assembly 911 with the non-closed annular protrusion.

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

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

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

[0129] like Figure 12 As shown, in some embodiments, the reflecting surface 9115 includes an emitting reflecting surface 9115a and a receiving reflecting surface 9115b. The emitting reflecting surface 9115a is arranged corresponding to the emitting collimating lens and the light emitting chip 3031, and the receiving reflecting 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 reflecting 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 reflecting surface 9115b, and the reflected optical signal is incident on the light receiving chip 3032.

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

[0131] In some embodiments, the optical port slot 9111 includes an emission optical port slot 9111a and a receiving optical port slot 9111b, which are separated from each other. An emission septum protrusion is provided within the emission optical port slot 9111a, and a receiving septum protrusion is provided within the receiving optical port slot 9111b. The emission septum protrusion and the receiving septum protrusion are not connected. The emission septum protrusion includes a first emission septum protrusion 9122a. A second emission septum protrusion 9123a protruding outward is provided at one end of the first groove wall of the first emission septum protrusion 9122a. The other end of the first groove wall of the first emission septum protrusion 9122a forms an emission reflection surface 9115a.

[0135] 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 surface of the three side walls of the wrapping cavity 9112 away from the circuit board 300 and the one side wall of the wrapping cavity 9112 close to the circuit board 300 enclose the dispensing surface 91124 of the wrapping cavity 9112. That is, the second sealant is located around each side surface of the fiber support 912 and the outer side surface of the three side walls of the wrapping cavity 9112 away from the circuit board 300 and the one side wall of the wrapping cavity 9112 close to the circuit board 300.

[0136] In some embodiments, the outer side of the second wrapping sidewall 91123 includes a first outer portion 91126 and a second outer portion 91127. The first outer portion 91126 is connected to the second outer portion 91127. The first outer portion 91126 is also connected to the outer side 91125 of the first wrapping sidewall 91121. The first outer portion 91126 is located between the outer side 91125 and the second outer portion 91127 of the first wrapping sidewall 91121. The outer side 91125 and the first outer portion 91126 of the first wrapping sidewall 91121 are vertical surfaces, and the second outer portion 91127 is an inclined surface.

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

[0138] like Figure 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. In this way, when the optical fiber bracket 912 is inserted into the wrapping cavity 9112, the first positioning column 9118 is inserted into the first positioning hole 9126 to position and install the optical fiber bracket 912.

[0139] The first end face of the optical fiber holder 912 is also provided with an optical fiber hole, and the second end face of the optical fiber holder 912 (the opposite side of the first end face of the optical fiber holder 912) is provided with an optical fiber jack, which is connected to the optical fiber jack, so that the optical fiber 9127 is inserted into the optical fiber hole through the optical fiber jack, and the light incident surface of the optical fiber 9127 can be located inside the optical fiber holder 912, or it can protrude from the first end face of the optical fiber holder 912.

[0140] Insert the optical fiber 9127 into the optical fiber holder 912 through the optical fiber jack, and use the first sealing glue to seal all the gaps between the optical fiber 9127 and the optical fiber jack. The first sealing glue is added to the periphery of the contact point between the optical fiber 9127 and the optical fiber jack, and is accumulated on the second end face of the optical fiber 9127 and the optical fiber holder 912. After the first sealing glue is cured, a fourth sealing member is formed to prevent the cooling liquid from extending into the interior of the optical fiber holder 912 from the optical fiber jack.

[0141] like Figure 14 As shown, an observation hole 9125 is further provided at the upper end of the optical fiber holder 912. This observation hole 9125 is connected to the optical fiber hole in the optical fiber holder 912, and the insertion of the optical fiber 9127 into the optical fiber holder 912 can be checked through the observation hole 9125. After the optical fiber 9127 is inserted into the optical fiber holder 912 through the optical fiber insertion hole, a first sealing glue can be added to the observation hole 9125 to form a seal, thereby sealing the observation hole 9125 and preventing the coolant from seeping into the interior of the optical fiber holder 912 through the observation hole 9125.

[0142] 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 each side of the fiber holder 912, and the clamping wall 91122 is arranged corresponding to the first end surface of the fiber holder 912, so as to wrap the fiber holder 912 in the wrapping cavity 9112.

[0143] In some embodiments, the length of the first wrapping side wall 91121 is less than or equal to the length of the side of the fiber holder 912 corresponding to the first wrapping side wall 91121, so that the dispensing needle can be directly placed on the fiber holder 912, and the dispensing needle can be used to dispense glue in the gap between the first wrapping side wall 91121 and the fiber holder 912.

[0144] In some embodiments, the length of the fourth wrapping side wall is less than the length of the side of the fiber holder 912 corresponding to the fourth wrapping side wall, that is, the area of the fiber holder 912 except the fiber 9127 is located outside the wrapping cavity 9112. Since the distance between the fiber holder 912 and the circuit board 300 is small, the dispensing needle cannot be conveniently inserted between the fiber holder 912 and the circuit board 300, that is, it is not convenient to dispense glue in the gap between the fourth wrapping side wall and the fiber holder 912.

[0145] In some embodiments, the length of the fourth wrapping side wall is greater than or equal to the length of the side of the fiber holder 912 corresponding to the fourth wrapping side wall, that is, the area of the fiber holder 912 except the fiber 9127 is located in the wrapping cavity 9112, so that the dispensing needle can be directly placed on the fourth wrapping side wall of the wrapping cavity 9112, and the dispensing needle can be used to dispense glue in the gap between the fourth wrapping side wall and the fiber holder 912.

[0146] Since the length of the side of the fiber holder 912 corresponding to the first wrapping side wall 91121 and the length of the side of the fiber holder 912 corresponding to the fourth wrapping side wall are the same, the length of the first wrapping side wall 91121 is less than the length of the fourth wrapping side wall, so that the fiber holder 912 can be completely wrapped, and the dispensing needle can be used to dispense glue in the gap between the wrapping cavity 9112 and the fiber holder 912.

The air in the cover cavity 9124 expands and is released through the second air vent hole 9119b, the second air vent hole 9119b is filled with the second sealant, and the second sealant solidifies to form a twelfth sealing member to block the second air vent hole 9119b to prevent the coolant from seeping into the cover cavity 9124 through the second air vent hole 9119b. The air in the wrapping cavity 9112 expands and is released through the first air vent hole 9119a, the first air vent hole 9119a is filled with the second sealant, and the second sealant solidifies to form a twelfth sealing member to block the first air vent hole 9119a to prevent the coolant from seeping into the wrapping cavity 9112 through the first air vent hole 9119a.

[0148] In some embodiments, the spreading range of the second sealing member in the gap between the first wrapping side wall 91121 and the top surface of the optical fiber support 912 does not exceed the first air vent hole 9119a, so that the second sealing member does not block the first air vent hole 9119a, to facilitate the release of the air in the wrapping cavity 9112 through the first air vent hole 9119a.

As shown, Figure 16 As shown, in some embodiments, the air vent hole 9119 includes a second air vent hole 9119b located above the cover cavity 9124 and an air vent hole 9119c located below the wrapping cavity 9112, the second air vent hole 9119b being in communication with the cover cavity 9124. The air in the cover cavity 9124 expands and is released through the second air vent hole 9119b, the air in the wrapping cavity 9112 expands and is released into the cover cavity 9124 through the air vent hole 9119c and then through the second air vent hole 9119b, the second air vent hole 9119b is filled with the second sealant, and the second sealant solidifies to form a twelfth sealing member to block the second air vent hole 9119b to prevent the coolant from seeping into the cover cavity 9124.

[0150] Figure 17 A third structure diagram of the first lens assembly according to some embodiments at a third viewing angle. As shown, Figure 14 and Figure 17As shown, in some embodiments, the air vent hole 9119 includes a first air vent hole 9119a located above the wrapping cavity 9112 and a vent hole 9119c located below the wrapping cavity 9112, and the first air vent hole 9119a is in communication with the wrapping cavity 9112. The air in the cover cavity 9124 is released to the wrapping cavity 9112 through the vent hole 9119c, and then released through the first air vent hole 9119a. The air in the wrapping cavity 9112 is released through the first air vent hole 9119a, and the first air vent hole 9119a is filled with the second sealant. The second sealant solidifies to form a twelfth sealing member, and the twelfth sealing member blocks the first air vent hole 9119a to prevent the cooling liquid from entering the cover cavity 9124.

[0151] As shown in Figure 15 , Figure 16 and Figure 17 , the second lens 9117 includes a transmitting collimating lens 9117a and a receiving coupling lens 9117b. The transmitting collimating lens 9117a is arranged corresponding to the light transmitting chip 3031 and the transmitting reflecting surface 9115a, and the receiving coupling lens 9117b is arranged corresponding to the light receiving chip 3032 and the receiving reflecting surface 9115b.

[0152] Figure 18 The first optical path diagram of the first optical transceiver component according to some embodiments is provided. Figure 19 The second optical path diagram of the second optical transceiver component according to some embodiments is provided. As shown in Figure 18 , in some embodiments, the angle between the transmitting reflecting surface 9115a and the horizontal plane is the same as the angle between the receiving reflecting surface 9115b and the horizontal plane, and both are 45°. The angle between the plane where the transmitting collimating lens 9117a is located and the horizontal plane is the same as the angle between the plane where the receiving coupling lens 9117b is located and the horizontal plane, and both are 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 light transmitting chip 3031 and the light receiving chip 3032 are arranged side by side along the width direction of the circuit board 300.

[0153] The optical transmitter chip 3031 emits a divergent light beam upward. The divergent light beam is converted into a collimated light beam by the transmitting collimating lens 9117a. The collimated light beam is then reflected by the transmitting reflective surface 9115a. The reflected collimated light beam is then converted into a convergent light beam by the transmitting coupling lens and coupled to the optical fiber. The optical fiber is then transmitted to the optical receiver chip in the optical module at the other end of the optical fiber. The light beam emitted by the optical transmitter chip at the other end of the optical fiber is transmitted through the optical fiber to the receiving collimating lens. The receiving collimating lens collimates the light beam into a collimated light beam. The collimated light beam is then reflected by the receiving reflective surface 9115b. The reflected collimated light beam is then directed vertically downward, coupled by the receiving coupling lens 9117b, and vertically incident on the optical receiver chip 3032.

[0154] 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.

[0155] The angle between the receiving reflective surface 9115b and the horizontal plane is 45 degrees. The part of the light beam that is 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. In order to solve this problem, Figure 19 As shown, in some embodiments, the angle between the emitting reflective surface 9115a and the horizontal plane is 45°, and the angle α between the receiving reflective surface 9115b and the horizontal plane is less than 45°. For example, the angle α between the receiving reflective surface 9115b and the horizontal plane is 30° to 38°, and the angle α between the receiving reflective surface 9115b and the horizontal plane is 39° to 42°.

[0156] The angle between the transmitting reflective surface 9115a and the horizontal plane is 45°, the angle between the surface on which the transmitting collimating lens 9117a is located and the horizontal plane is 0°, the angle between the receiving reflective surface 9115b and the horizontal plane is less than 45°, and the surface on which the receiving coupling lens 9117b is located is moved backward relative to the surface on which the transmitting collimating lens 9117a is located and is tilted, i.e., the angle between the surface on which the receiving coupling lens 9117b is located and the horizontal plane changes from 0° to β. The transmitting collimating lens 9117a and the receiving coupling lens 9117b are staggered along the width direction of the first lens assembly 911. According to the reflection theorem, the angle deflection angle γ between the receiving reflective surface 9115b and the horizontal plane is 45°-α, and the angle deflection angle β between the surface on which the receiving reflective surface 9115b is located and the horizontal plane is 2γ, i.e., the angle β between the surface on which the receiving coupling lens 9117b is located and the horizontal plane is equal to 2*(45°-α).

[0157] The emitting collimating lens 9117a and the receiving coupling lens 9117b are staggered along the width direction of the first lens assembly 911, and then 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 and vertical distance between the light emitting chip 3031 and the light receiving chip 3032 is L=H*tanβ, wherein H is the vertical distance between the reflecting surface 9115 and the light chip 303.

[0158] The light emitting chip 3031 emits a divergent light beam upward, the divergent light beam is converted into a collimated light beam by the emitting collimating lens 9117a, the collimated light beam is reflected by the emitting reflecting surface 9115a, and the reflected collimated light beam is converted into a convergent light beam by the emitting coupling lens and coupled into the optical fiber, and the optical fiber transmits the light beam to the light receiving chip in the optical module at the other end of the optical fiber. The light beam emitted by the light emitting chip at the other end of the optical fiber is transmitted by the optical fiber to the receiving collimating lens, collimated into a collimated light beam by the receiving collimating lens, and reflected by the receiving reflecting surface 9115b. The reflected collimated light beam is obliquely downward, and after being coupled by the receiving coupling lens 9117b, it is obliquely incident on the light receiving chip 3032. The light beam obliquely incident on the light receiving chip 3032 is reflected on the light receiving chip 3032, and the reflected light beam is not returned along the original path, but is obliquely upward, thereby avoiding the influence of the light beam returning to the optical fiber 9127 on the performance of the light emitting chip at the other end of the optical fiber 9127.

[0159] The angle between the emitting reflecting surface 9115a and the horizontal plane and the angle between the receiving reflecting surface 9115b and the horizontal plane are not the same size, the emitting light port groove 9111a provided with the emitting reflecting surface 9115a and the receiving light port groove 9111b provided with the receiving reflecting surface 9115b are connected to form a light port groove 9111, that is, the emitting reflecting surface 9115a and the receiving reflecting surface 9115b form two reflecting surfaces with different angles, which is convenient for processing.

[0160] The angle between the emitting reflecting surface 9115a and the horizontal plane and the angle between the receiving reflecting surface 9115b and the horizontal plane are not the same size, the emitting light port groove 9111a provided with the emitting reflecting surface 9115a and the receiving light port groove 9111b provided with the receiving reflecting surface 9115b are not connected, that is, the emitting reflecting surface 9115a and the receiving reflecting surface 9115b are also not connected, and the light port groove 9111 is narrowed to ensure that the second sealant cannot flow onto the reflecting surface 9115.

One end of the first lens assembly is provided with a wrapping cavity, the top surface of the wrapping cavity is flush with the top surface of the region of the first lens assembly except the wrapping cavity, so as to facilitate the coupling and mounting of the first lens assembly on the circuit board; one side of the wrapping cavity is provided with an opening, the fiber support is inserted into the wrapping cavity through the opening, the first end surface of the fiber support is embedded in the wrapping cavity, the first sealing glue is dispensed on the dispensing surface of the wrapping cavity, so that the first end surface of the fiber support is far away from the position where the first sealing glue is located, and thus the first end surface of the fiber support is not easily polluted by the first sealing glue; after the first sealing glue is solidified, a second sealing member is formed, the second sealing member is located on each side surface of the fiber support, the outer side surface of the three side walls of the wrapping cavity away from the circuit board, and the surrounding of one side wall of the wrapping cavity close to the circuit board, so as to completely seal the gap between the fiber support and the wrapping cavity through the second sealing member, so as to ensure the sealed connection between the fiber support and the first lens assembly, and thus isolate the cooling liquid. The wrapping cavity has a first air hole, the first air hole is located on the side wall of the wrapping cavity away from the circuit board, and the spreading range of the second sealing member in the gap between the top surface of the fiber support and the wrapping cavity does not exceed the first air hole, so as to release the air in the wrapping cavity. A twelfth sealing member is arranged in the first air hole, the twelfth sealing member is used to block the first air hole to prevent the cooling liquid from penetrating into the interior of the first lens assembly through the first air hole. The first lens assembly is provided with a recessed optical port groove and a blocking assembly, the blocking assembly covers the optical port groove to block the cooling liquid from penetrating into the optical port groove; the other end of the groove wall of the optical port groove forms a reflecting surface, the reflecting surface is used to reflect the light generated by the optical chip into the wrapping cavity, so that the light is input into the fiber support in the wrapping cavity to realize the reflection of the light. One end of the groove wall of the optical port groove forms a glue blocking protrusion, the glue blocking protrusion is used to narrow the optical port groove and support the sealing member in the optical port groove to prevent the sealing member in the optical port groove from penetrating into the reflecting surface. In some embodiments, the cooling liquid is isolated by the first sealing member, the second sealing member and the blocking assembly to avoid the pollution of the cooling liquid to the optoelectronic devices in the first lens assembly; the sealing glue is isolated by the first end surface of the fiber support embedded in the wrapping cavity and the glue blocking protrusion to avoid the pollution of the sealing glue to the optical path of the first lens assembly and the fiber support, and thus ensure the normal work of the optical module.In some embodiments, the twelfth seal is arranged in the first seal, the second seal, the baffle and the first air vent to isolate the coolant to avoid the coolant from contaminating the optoelectronic device in the first lens assembly; the first end surface of the optical fiber holder is embedded in the wrapping cavity to isolate the sealing glue to avoid the sealing glue from contaminating the optical path between the first lens assembly and the optical fiber holder, thereby ensuring the normal operation of the optical module; the spreading range of the second seal in the gap between the top surface of the optical fiber holder and the wrapping cavity does not exceed the first air vent, so that the air in the wrapping cavity can be released.

Figure 21 An exploded view of the second optical transceiver component according to some embodiments. Figure 22 A sectional view of the second optical transceiver component according to some embodiments. Figure 20 Figure 21 and Figure 22 ​As shown, in some embodiments, the second optical transceiver component 902 includes a second lens assembly 921, a fiber holder 922, and a sealing cover plate 923, the sealing cover plate 923 is arranged on the second lens assembly 921, one end of the second lens assembly 921 is provided with a clamping groove 9212, one end of the fiber holder 922 is fixed with an optical fiber 9223, the fiber holder 922 carrying the optical fiber 9223 is inserted into the clamping groove 9212 to realize the connection between the fiber holder 922 and the second lens assembly 921. After the fiber holder 922 is inserted into the clamping groove 9212, a second sealing member is arranged between the fiber holder 922 and the side walls of the clamping groove 9212. That is, after the fiber holder 922 is inserted into the clamping groove 9212, the gap between the side walls of the clamping groove 9212 and the corresponding sides of the fiber holder 922 is completely sealed by the first sealing glue, and the first sealing glue accumulates at the connection between the side walls of the clamping groove 9212 and the corresponding sides of the fiber holder 922. In this way, the first sealing glue forms a second sealing member after curing to ensure the sealing performance of the connection between the sides of the fiber holder 922 except the top surface and the second lens assembly 921, thereby preventing the cooling liquid from seeping in. 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 fiber holder 922 on the clamping groove 9212, and the first end surface of the fiber holder 922 is located on the bottom surface of the sealing cover plate 923. The first sealing glue is applied to the outer side wall of the sealing cover plate 923, so that the first end surface of the fiber holder 922 is far away from the position where the first sealing glue is located, thereby preventing the first end surface of the fiber holder 922 from being contaminated by the first sealing glue. The first sealing glue forms a fifth sealing member after curing, and the fifth sealing member is located on the outer side wall of the sealing cover plate 923, the second lens assembly 921, and the fiber holder 922 to isolate the cooling liquid. That is, after the sealing cover plate 923 covers the second lens assembly 921 and the fiber holder 922, the first sealing glue is applied to the outer side wall of the sealing cover plate 923 to completely seal the gap between the sealing cover plate 923, the second lens assembly 921, and the fiber holder 922, and the first sealing glue accumulates between the sealing cover plate 923, the second lens assembly 921, and the fiber holder 922. In this way, the first sealing glue forms a fifth sealing member after curing to ensure the sealing performance of the connection between the sealing cover plate 923, the second lens assembly 921, and the fiber holder 922, thereby preventing the cooling liquid from seeping in.

[0163] As Figure 22As shown, the first lens 9216 is arranged in the clamping groove 9212, and the first lens 9216 is arranged corresponding to the optical fiber support 922. The first lens 9216 includes a receiving collimating lens and a transmitting coupling lens. The transmitting coupling lens couples the light beam transmitted by the second lens assembly 921, and the receiving collimating lens collimates the light beam of the optical fiber 9223 in the optical fiber support 922.

[0164] As shown in Figure 21 and Figure 22 The light port groove 9211 is arranged on the second lens assembly 921, and the top surface (the plane away from the circuit board 300) of the light port groove 9211 is provided with an opening. The groove wall of the light port groove 9211 forms a reflecting surface 9215, which is arranged opposite to the first lens 9216. Thus, the light 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 transmitted through the first lens 9216. The light beam transmitted by the optical fiber is reflected by the reflecting surface 9215, and the reflected light signal is incident on the optical chip 303 (specifically, the optical receiving chip 3032).

[0165] The reflecting surface 9215 includes a transmitting reflecting surface and a receiving reflecting surface. The transmitting reflecting surface is arranged corresponding to the transmitting collimating lens and the optical transmitting chip, and the receiving reflecting surface is arranged corresponding to the receiving coupling lens and the optical receiving chip 3032. The light signal emitted by the optical transmitting chip 3031 is reflected by the transmitting reflecting surface, and the reflected light signal is transmitted through the first lens 9216. The light signal transmitted by the optical fiber is reflected by the receiving reflecting surface, and the reflected light signal is incident on the optical receiving chip 3032.

[0166] The top surface of the light port groove 9211 is provided with an opening to facilitate the demolding process of the plastic mold. In order to prevent the cooling liquid from seeping into the second lens assembly 921 through the opening of the light port groove 9211, the sealing cover plate 923 is arranged on the light port groove 9211. The size of the sealing cover plate 923 corresponding to the light port groove 9211 is greater than the size of the opening of the light port groove 9211, so that the sealing cover plate 923 can seal the opening of the light port groove 9211 to reduce the seepage of the cooling liquid into the light port groove 9211 and ensure that the light port groove 9211 is isolated from the cooling liquid.

[0167] In some embodiments, to prevent the first sealant from flowing into the reflective surface 9215, a sealant-isolating protrusion is provided at one end of the wall of the optical port slot 9211. This sealant-isolating protrusion narrows the optical port slot 9211, forming a deep well. Due to the high viscosity of the first sealant, it can only coat the upper portion of the deep well (i.e., the sealant-isolating protrusion of the optical port slot 9211). The air below the deep well supports the first sealant, preventing it from flowing downward onto the reflective surface 9215. This ensures that the reflective surface 9215 is both isolated from the external coolant and unaffected by the first sealant.

[0168] In some embodiments, the sealant protrusions include first sealant protrusions, which are formed by outwardly protruding from the walls of the optical aperture slot 9211. The first sealant protrusions narrow the optical aperture slot 9211, forming a deep well. Due to the viscosity of the first sealant, it can only coat the first sealant protrusions in the upper portion of the deep well. The air below the deep well supports the first sealant, preventing it from flowing downward onto the reflective surface 9215. This ensures that the reflective surface 9215 is both isolated from the external coolant and unaffected by the first sealant.

[0169] In some embodiments, the sealant protrusions further include a second sealant protrusion. The second sealant protrusion is formed by protruding outward from the first groove wall of the first sealant protrusion (referring to the groove wall where the reflective surface is located in the optical port groove 9211). The second sealant protrusion further narrows the optical port groove 9211, forming a deep well groove. Due to the viscosity of the first sealant, it can only cover the first and second sealant protrusions in the upper portion of the deep well groove. The air in the lower portion of the deep well groove supports the first sealant, preventing it from flowing downward onto the reflective surface 9215. This ensures that the reflective surface 9215 is both isolated from the external coolant and unaffected by the first sealant.

[0170] In some embodiments, the second lens assembly 921 is provided with an inclined surface 9213, which slopes along the top surface of the second lens assembly 921 toward the side of the second lens assembly 921 away from the fiber optic bracket 912. In other words, the inclined surface 9213 is a downwardly inclined surface. The rear optical fiber 9223 tilts upward along the inclined surface 9213, giving the optical fiber 9223 a larger bending radius, thereby avoiding fiber transmission problems caused by a fiber radius that is too small.

[0171] like Figure 22As shown, the second lens assembly 921 is provided with a cover cavity 9222 on the side facing the circuit board 300, and the inner side wall of the cover cavity 9222 is provided with a second lens 9217 located below the reflecting surface 9215, and the light chip 303 is located below the second lens 9217. The second lens 9217 can be a transmitting collimating lens, and the light chip 303 is a light emitting chip. Thus, the light beam emitted by the light emitting chip is converted into a collimated light beam by the transmitting collimating lens, the collimated light beam is reflected by the reflecting surface 9215, and the reflected collimated light beam is converted into a converging light beam by the first lens 9216 and coupled to the optical fiber. The second lens can also be a receiving coupling lens, and the light chip 303 is a light receiving chip. Thus, the receiving light beam is reflected by the reflecting surface 9215 through the first lens 9216, and the reflected receiving light beam is coupled to the light receiving chip by the receiving coupling lens.

[0172] In some embodiments, the sealing cover plate 923 and the clamping groove 9212 form a wrapping cavity, the sealing cover plate 923 is provided with a first air hole, and the air expanded in the wrapping cavity is released through the first air hole. The first air hole is filled with the second sealing glue, and the second sealing glue is solidified to form a twelfth sealing member for sealing the first air hole to prevent the cooling liquid from penetrating into the wrapping cavity through the first air hole.

[0173] In some embodiments, the second lens assembly 921 is also provided with a second air hole 9219 located above the cover cavity 9222, and the second air hole 9219 is in communication with the cover cavity 9222. The air expanded in the cover cavity 9222 is released through the air hole 9219 to prevent the cooling liquid from penetrating in.

As shown, Figure 23 In some embodiments, the light port groove 9211 only includes one light port groove provided with a transmitting reflecting surface and a receiving reflecting surface in communication.

[0177] like Figure 19 As shown, in some embodiments, the angle between the emitting reflection surface of the second lens assembly 921 and the horizontal plane is different from the angle between the receiving reflection surface of the second lens assembly 921 and the horizontal plane. The angle between the emitting reflection surface of the second lens assembly 921 and the horizontal plane is 45°, the angle α between the receiving reflection surface of the second lens assembly 921 and the horizontal plane is less than 45°, the angle between the surface where the emitting collimating lens of the second lens assembly 921 is located and the horizontal plane is 0°, the angle β between the surface where the receiving coupling lens of the second lens assembly 921 is located and the horizontal plane is 2*(45°-α), the emitting collimating lens of the second lens assembly 921 and the receiving coupling lens of the second lens assembly 921 are staggered along the width direction of the second lens assembly 921, 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 and vertical distance between the light emitting chip 3031 and the light receiving chip 3032 is L=H*tanβ.

[0215] In some embodiments, the optical cable 108 further comprises an optical cable fixing member 181, the optical cable fixing member 181 is wrapped on one end of the outside of the optical cable body 182, the optical cable fixing member 181 is clamped on the optical module 200, and the optical cable fixing member 181 is used to fix the optical cable fixing member 181 in the shell of the optical module 200 and prevent the cooling liquid inside the optical module 200 from seeping into the inside of the optical cable body 182.

[0216] In some embodiments, the optical cable 108 further comprises an isolation member 183, the isolation member 183 is wrapped on the middle of the outside of the optical cable body 182, and the isolation member 183 is used to isolate the cooling liquid from one end of the optical cable 108 to prevent the cooling liquid from seeping from one end of the optical cable body 182 to the other end of the optical cable body 182. Wherein, the middle of the outside of the optical cable body 182 is only used to indicate the two ends of the outside of the optical cable body 182, but not the middle of the outside of the optical cable body 182, i.e. the middle of the outside of the optical cable body 182 is not the middle point of the outside of the optical cable body 182.

[0217] In some embodiments, the optical cable 108 further comprises an optical cable fixing member 181 and an isolation member 183, the optical cable fixing member 181 is wrapped on one end of the outside of the optical cable body 182, the optical cable fixing member 181 is clamped on the optical module 200, and the optical cable fixing member 181 is used to fix the optical cable fixing member 181 in the shell of the optical module 200 and prevent the cooling liquid inside the optical module 200 from seeping into the inside of the optical cable body 182, and the isolation member 183 is wrapped on the middle of the outside of the optical cable body 182, and the isolation member 183 is used to isolate the cooling liquid from one end of the optical cable 108.

[0218] Figure 37 An exploded view of the optical cable fixing member according to some embodiments. Figure 38 An assembly view of the clamp, the first crimping ring and the second crimping ring according to some embodiments. Figure 39 An assembly view of the clamp and the first crimping ring according to some embodiments. As shown inFigure 37 、 Figure 38 and Figure 39 As shown, in some embodiments, the optical cable fixing member 181 includes a clamp 1811, one end of the clamp 1811 is engaged with the optical port of the optical module 200, and the other end of the clamp 1811 is arranged adjacent to the cable sheath 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. 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.

[0219] To ensure that the fifth sealant not only seals but also protects the optical cable, in some embodiments, the fifth sealant is a soft glue. For example, the fifth sealant is silicone. Clamp 1811 includes a clamp body 1815 and a stop protrusion 1816. Clamp body 1815 is located at one end of clamp 1811, and stop protrusion 1816 is located at the other end of clamp 1811 (closer to the optical module relative to clamp body 1815). The inner sides of clamp body 1815 and stop protrusion 1816 form a first cavity.

[0220] In some embodiments, the optical cable fixture 181 further includes a second crimping ring 1813. One end of the second crimping ring 1813 is crimped onto the reinforcement wire 1823 on the outside of the clamp 1811, and the other end of the second crimping ring 1813 is crimped onto the cable sheath 1821, thereby compressing the optical cable fixture 181 and the reinforcement wire 1823 to ensure that the required tension of the optical cable 108 is met. When the second crimping ring 1813 is pushed to the stop protrusion 1816 on the outside of the clamp 1811, the end of the reinforcement wire 1823 (Kevlar) passes over the second crimping ring 1813, ensuring that the required tension of the optical cable body 182 is met.

[0221] But the cooling liquid will seep into the inside of the optical cable body 182 along the reinforcing wire 1823 (Kevlar) if the end of the reinforcing wire 1823 (Kevlar) goes beyond the second crimping ring 1813. In order to avoid the cooling liquid seeping into the inside of the optical cable body 182 along the reinforcing wire 1823 (Kevlar), in some embodiments, the optical cable fixing member 181 further comprises the first crimping ring 1812 and the second crimping ring 1813, the first crimping ring 1812 is arranged outside the clamp body 1815, the first crimping ring 1812 is located before the stop protrusion 1816, the reinforcing wire 1823 is arranged between the outside of the clamp 1811 and the first crimping ring 1812 to crimp the reinforcing wire 1823 on the outside of the clamp body 1815, one end of the second crimping ring 1813 is crimped on the right end of the outside of the first crimping ring 1812, the second crimping ring 1813 is crimped on the reinforcing wire 1823 outside the clamp body 1815 in the middle, and the other end of the second crimping ring 1813 is crimped on the cable skin 1821 to press the optical cable fixing member 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 outside the clamp 1811, wrap the end of the reinforcing wire 1823 (Kevlar) in the first crimping ring 1812, and crimp the first crimping ring 1812 to crimp the Kevlar 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 to crimp the second crimping ring 1813 on the first crimping ring 1812, the reinforcing wire 1823 outside the clamp 1811 and the cable skin 1821, thereby ensuring that the tension of the optical cable 108 meets the requirements.

[0222] In some embodiments, the reinforcing wire 1823 cannot go beyond the left end of the first crimping ring 1812 to avoid the cooling liquid outside the optical module seeping into the inside of the optical cable body 182 along the reinforcing wire 1823.

[0223] After the second crimping ring 1813 is crimped, it is necessary to observe whether the second crimping ring 1813 is flat, whether there is a broken thread, and whether the first crimping ring 1812 is clearly visible. After observing that the second crimping ring 1813 is flat, there is no broken thread, and the first crimping ring 1812 is clearly visible, the tension test is performed to make the tension of the optical cable reach 15 Kg / min.

[0224] After the tension test is completed, the sixth sealant is applied on the outside of the first crimp ring 1812, at the gap between the first crimp ring 1812 and the clamp body 1811, at the connection between the first crimp ring 1812 and the second crimp ring 1813, and at the connection between the second crimp ring 1813 and the optical cable body 182. After the silicone is left still for a period of time, the sixth sealant on the outside of the first crimp ring 1812, at the gap between the first crimp ring 1812 and the clamp body 1811, and at the connection between the first crimp ring 1812 and the second crimp ring 1813 solidifies to form an eighth seal, and the sixth sealant at the position of the optical cable body 182 solidifies to form a ninth seal. The eighth seal not only seals the gap between the first crimp ring 1812 and the second crimp ring 1813 to ensure that the first crimp ring 1812 and the second crimp ring 1813 are sealingly connected, but also seals the gap between the first crimp ring 1812 and the clamp body 1811 to ensure that the clamp body 1811 and the first crimp ring 1812 are sealingly connected, and isolates the first crimp ring 1812 from the cooling liquid to prevent the cooling liquid from penetrating into the optical fiber 1822 inside the optical cable body 182 through the reinforcing wire 1823. The ninth seal seals the gap between the optical cable body 182 and the second crimp ring 1813 to ensure that the second crimp ring 1813 and the optical cable body 182 are sealingly connected.

[0225] In some embodiments, the sixth sealant is a soft glue. For example, the fifth sealant is silicone.

[0226] The optical cable fixing member 181 further includes a protective sleeve 1814 covering the eighth seal, the second crimp ring 1813, and the cable skin 1821 to protect the optical cable body 182. The height of the eighth seal should not exceed the height of the second crimp ring 1813 to avoid the protective sleeve 1814 being unable to push down to the fixed position of the clamp 1811, i.e., the protective sleeve 1814 is fixed before the stop protrusion 1816 of the clamp 1811. The eighth seal uniformly covers the first crimp ring 1812 to further avoid the exposure of the reinforcing wire 1823 to the cooling liquid, and the ninth seal uniformly covers the gap between the optical cable body 182 and the second crimp ring 1813 to further ensure that the second crimp ring 1813 and the optical cable body 182 are sealingly connected.

The reinforcing wire is arranged between the first crimping ring and the clamp to crimp the reinforcing wire on the clamp. The reinforcing wire cannot 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.

[0236] Figure 40 The exploded view of the optical cable body and the isolation member according to some embodiments is provided. Figure 41 The cross-sectional view of the optical cable body and the isolation member according to some embodiments is provided. As shown in Figure 40 and Figure 41 In some embodiments, the isolation member 183 includes an isolation sleeve 1831, and the isolation sleeve 1831 is internally provided with a second cavity. The second cavity is internally provided with a second optical cable body and a tenth seal. The tenth seal fills the gap between the second optical cable body and the isolation sleeve 1831 to prevent the cooling liquid from penetrating from one end of the optical cable body 182 to the other end of the optical cable body 182.

[0237] In some embodiments, the isolation member 183 includes an isolation sleeve 1831, and the isolation sleeve 1831 is internally provided with a second cavity. The second cavity is internally provided with a second optical cable body and a tenth seal. The tenth seal fills the gap between the second optical cable body and the isolation sleeve 1831 to prevent the cooling liquid from penetrating from one end of the optical cable body 182 to the other end of the optical cable body 182.

[0238] The length of the broken reinforcing line in the second cavity is 3-5 mm, so as to ensure that the tensile force of the isolation member 183 meets the requirements.

[0239] The isolation sleeve 1831 includes a first inner plug and a second inner plug, which are identical in shape. The first inner plug and the second inner plug are connected to form the isolation sleeve 1831 having a second cavity and two first through holes 1837. A seventh sealant is applied on the bottom of the first inner plug, the cut optical cable body is installed inside the first inner plug, and a layer of the seventh sealant is applied to completely block the two end cutouts of the cut optical cable body. The second inner plug is covered, and the first inner plug and the second inner plug are fixed with a masking tape. The fixed first inner plug and second inner plug are placed in a high-temperature 100℃ environment for drying for more than 1h, and the seventh sealant is cured to form a tenth sealant.

[0240] In some embodiments, the isolation member 183 further includes a protection tail pipe 1833 and a protection tail pipe 1834, which are respectively arranged on both ends of the isolation sleeve 1831 to protect the optical cable body. After the seventh sealant in the isolation sleeve 1831 is cured into the tenth sealant, the protection tail pipe 1833 is arranged on both ends of the isolation sleeve 1831.

[0241] The protection tail pipe 1833 is provided with a third through hole 1839 corresponding to the first through hole 1837, so as not to allow the optical cable body 182 to pass through the first through hole 1837 and the third through hole 1839.

[0242] The protection tail pipe 1833 and the protection tail pipe 1834 each include a clamping end and a protection end. One end of the clamping end is arranged on both ends of the isolation sleeve 1831, the other end of the clamping end is connected to one end of the protection end, and the other end of the protection end wraps the optical cable body 182. One end of the protection end is not parallel to the other end of the protection end, so that the protection end has a certain inclination angle.

[0243] In some embodiments, the inclination angle of the protection end is not equal to 90°, so as to reduce the stress received by the optical cable body 182 and protect the optical cable body 182.

[0245] However, since the isolation sleeve 1831 is composed of the first inner plug and the second inner plug, a gap exists at the connection between the first inner plug and the second inner plug, so that the strength of the isolation sleeve 1831 at the connection between the first inner plug and the second inner plug is poor, and the isolation sleeve 1831 is prone to be broken at the connection between the first inner plug and the second inner plug.

Figure 44 A cross-sectional view of the protection sleeve and the protection tail pipe according to some embodiments. As shown in Figure 42 、 Figure 43 and Figure 44 To avoid the breakage of the isolation sleeve 1831, in some embodiments, the isolator 183 further includes a protection sleeve 1832 and protection tail pipes 1833. The protection sleeve 1832 is arranged on the isolation sleeve 1831 to ensure the strength of the isolation sleeve 1831, and the two protection tail pipes 1833 are arranged on the two ends of the protection sleeve 1832 respectively to protect the optical cable body 182.

[0247] The two ends of the protection sleeve 1832 are provided with second through holes 1838, which are arranged correspondingly with the first through hole 1837 and the third through hole 1839 to avoid the optical cable body 1822, so that the optical cable body 182 passes through the first through hole 1837, the second through hole 1838 and the third through hole 1839.

[0248] The outer side of the protection sleeve 1832 is provided with two limiting protrusions 1835, which are respectively located at the two ends of the protection sleeve 1832. The protection sleeve 1832 is connected with the clamping end of the protection tail pipe 1833 to limit the clamping position of the protection tail pipe 1833 in the protection sleeve 1832. The inner side of the protection sleeve 1832 is provided with a third cavity, and the 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 protection sleeve 1832 to fill the gap between the optical cable body 182, the isolation sleeve 1831 and the protection sleeve 1832, thereby realizing the stable connection of the isolation sleeve 1831 and the protection sleeve 1832, and the sealed connection of the protection sleeve 1832 and the optical cable body 182.

[0249] In some embodiments, a limiting step 1836 is arranged in the third cavity inside the protection sleeve 1832, and the limiting step 1836 is used to limit the position of the isolation sleeve 1831 in the protection sleeve 1832. For example, one limiting step 1836 is arranged at one end of the third cavity inside the protection sleeve 1832, and the isolation sleeve 1831 is arranged between the limiting step 1836 and the other end of the third cavity to limit the position of the isolation sleeve 1831 in the protection sleeve 1832. For example, one limiting step 1836 is arranged at each end of the third cavity inside the protection sleeve 1832, and the isolation sleeve 1831 is arranged between the two limiting steps 1836 to limit the position of the isolation sleeve 1831 in the protection sleeve 1832.

[0250] In some embodiments, the area of the third cavity other than the isolation sleeve 1831 is provided with an eleventh sealing member between the limiting step 1836 and the inner wall of the protection sleeve 1832, which is not only used to achieve the fixed connection between the isolation sleeve 1831 and the protection sleeve 1832, but also used to achieve the sealed connection between the protection sleeve 1832 and the optical cable body 182, so as to further prevent the cooling liquid from seeping in.

[0251] The protection sleeve 1832 is a hollow cylinder (provided with a third cavity inside), and after the seventh sealing glue in the isolation sleeve 1831 is cured into the tenth sealing member, the isolation sleeve 1831 is inserted into the protection sleeve 1832 after being coated with the seventh sealing glue outside, and is placed in a high-temperature 100℃ condition for drying for more than 1h after being sealed with the seventh sealing glue at both ends of the protection sleeve 1832. Wait for the seventh sealing glue to cure to form the eleventh sealing member, and after the seventh sealing glue in the protection sleeve 1832 is cured into the eleventh sealing member, the protection tail pipe 1833 is sleeved at both ends of the protection sleeve 1832.

[0252] In some embodiments, the seventh sealing glue is a hard glue, for example, the seventh sealing glue is a hot melt glue. The sealing glue of the epoxy system is also a hard glue, but the hardness of the seventh sealing glue is smaller than that of the sealing glue of the epoxy system, and the hardness of the seventh sealing glue is larger than that of the fifth sealing glue and the sixth sealing glue.

[0253] In some embodiments, an optical cable is optically connected to an optical module, a coolant is contained within the optical module, and the optical cable includes an optical cable body.
