In the optical communication technology, in order to establish information transfer between information processing apparatuses, it is necessary to load information onto light, and transfer of information is realized by 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 the information transmission device, so that high-speed, long-distance and low-cost information transmission can be realized. The signal that the information processing apparatus can recognize and process is an electrical signal. Information processing devices typically include optical network terminals (Optical Network Unit, ONUs), gateways, routers, switches, handsets, computers, servers, tablets, televisions, etc., and information transmission devices typically include optical fibers, optical waveguides, etc.

The optical module can realize the mutual conversion of optical signals and electric signals between the information processing equipment and the information transmission equipment. For example, at least one of the optical signal input end or the optical signal output end of the optical module is connected 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 terminal; the optical module converts the first optical signal into a first electrical signal and transmits the first electrical signal to an optical network terminal; the second electrical signal from the optical network terminal is transmitted to the optical module, which converts the second electrical signal into a second optical signal and transmits the second optical signal to the optical fiber. Since information transmission can be performed between the plurality of information processing apparatuses by an electric signal, it is necessary that at least one of the plurality of information processing apparatuses is directly connected to the optical module, and it is unnecessary that all of the information processing apparatuses are directly connected to the optical module. Here, the information processing apparatus directly connected to the optical module is referred to as an upper computer of the optical module.

Fig. 5 is a cross-sectional view of an optical transceiver component and a circuit board provided in accordance with some embodiments. Fig. 6 is an exploded view of an optical transceiver component and a circuit board provided in accordance with some embodiments. As shown in fig. 5 and fig. 6, an optical matching chip 302 and an optical chip 303 are disposed on a circuit board 300, the optical matching chip 302 may be a bare chip such as a laser driving chip 3021 and/or a TIA chip 3022, and the bare chip is adhered to the circuit board 300 by silver paste to perform fixing and heat dissipation functions, and then the bare chip and the circuit board 300 are connected by gold wire bonding. The light chip 303 may be a light emitting chip 3031 and/or a light receiving chip 3032, and the light emitting chip 3031 and the light receiving chip 3032 may be fixed on the circuit board 300 side by side.

In some embodiments, the optical transceiver 900 includes a fiber support and a lens assembly, the fiber support being optically coupled to the lens assembly, the lens assembly being disposed over the optical matching chip 302 and the optical chip 303 on the circuit board 300 to place the optical matching chip 302 and the optical chip 303 in a cavity defined by the lens assembly and the circuit board.

Since the light chip 303 is attached to the circuit board 300, the light emitting surface or the light incident surface thereof is located on the top surface of the light chip 303, so that the light beam emitted by the light emitting chip is perpendicular to the circuit board 300, and the light beam received by the light receiving chip is perpendicular to the circuit board 300; the optical fiber 101 connected with the optical module is parallel to the circuit board 300, and the transmission direction of the light beam emitted by the light emitting chip and the external light beam transmitted to the light receiving chip needs to be changed, so that the light beam emitted by the light emitting chip is changed through the lens assembly, the light beam emitted by the light emitting chip is reflected through the lens assembly, and the reflected light beam is parallel to the circuit board 300, so that the reflected light beam is conveniently coupled into the optical fiber; the received light beam transmitted from the external optical fiber is reflected by the lens assembly, and the reflected light beam is perpendicular to the circuit board 300 to be conveniently received by the light receiving chip.

As shown in fig. 6, a DSP chip 301 is further provided on the circuit board 300, and the DSP chip 301 is used for processing high-frequency signals. After the high-frequency signal received by the light receiving chip 3032 at the receiving end is amplified by the TIA chip 3022, the high-frequency signal is transmitted to the DSP chip 301 for processing via a high-frequency signal line connecting the TIA chip 3022 and the DSP chip 301, and then the communication system is transmitted via the gold finger. The transmitting end is opposite, the golden finger receives the signal and then processes the signal through the DSP chip 301, the processed signal is transmitted to the laser driving chip 3021 through a signal line connecting the DSP chip 301 and the laser driving chip 3021, and then is transmitted to the optical transmitting chip 3031 to be converted into an optical signal, and the optical signal sent by the optical transmitting chip 3031 is coupled into an optical fiber through a lens assembly of the optical transceiver 900 to be transmitted.

With the increase of communication rate, although the power consumption per unit bandwidth is decreasing, the overall power consumption of the optical module is still further increasing, and the heat dissipation mode adopted in the client device is mostly air cooling, and for a high-speed transmission system, the heat dissipation capability of the high-speed transmission system has reached a limit. To overcome the dilemma of air cooling, various liquid cooling methods have been studied, one of which is to immerse the switch in a cooling liquid such as a fluorinated liquid (FC-40). However, due to the low cost requirement, the optical module deployed in the data center mostly adopts a non-sealing design structure, and key optical paths of the optical module are in an open state, so that when the optical module enters the refrigerating fluid along with the switch, the key optical paths and the parts also enter the refrigerating fluid, thereby causing the change of an optical mechanism and the pollution of an optical surface, and seriously affecting the normal operation of the optical module.

In some embodiments, in order to prevent the cooling liquid from penetrating into the optical chip 303 and the optical matching chip 302 inside the lens assembly through the gap between the lens assembly and the circuit board 300, a first sealing member is disposed 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, namely, sealing glue is added to the periphery of the contact part of 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 is accumulated on the surface of the circuit board 300 and the outer side wall of the lens assembly, so that the sealing glue is solidified to form the first sealing member. Illustratively, the lens assembly may be a first lens assembly with a first seal disposed between the first lens assembly and the circuit board 300; the lens assembly may be a second lens assembly with a first seal disposed between the second lens assembly and the circuit board 300; the lens assembly may be a third lens assembly with a first seal disposed between the third lens assembly and the circuit board 300.

In some embodiments, the sealing glue adopts the glue of an epoxy system, and the sealing glue of the epoxy system has excellent chemical corrosion resistance, heat resistance and bonding property and can better prevent the penetration of cooling liquid.

The sealing glue of the epoxy system can be first sealing glue, second sealing glue, third sealing glue and fourth sealing glue, the adhesive force of the first sealing glue, the adhesive force of the third sealing glue and the adhesive force of the fourth sealing glue are all larger than those of the second sealing glue, the viscosity of the first sealing glue is larger than that of the third sealing glue, the viscosity of the first sealing glue is larger than that of the fourth sealing glue, and the viscosity of the third sealing glue is smaller than that of the fourth sealing glue.

In some embodiments, to prevent coolant from penetrating into the optical path between the lens assembly and the fiber optic bracket through the gap between the lens assembly and the fiber optic bracket, a second seal is disposed between the fiber optic bracket and the lens assembly after the fiber optic bracket is inserted into the lens assembly.

The lens assembly is provided with a clamping groove, and the optical fiber support is placed in the clamping groove, namely three side faces of the clamping groove are respectively arranged corresponding to the side faces corresponding to the optical fiber support, and the clamping face of the clamping groove is arranged corresponding to the first end face of the optical fiber support. After the optical fiber support is placed in the clamping groove, first sealing glue is injected into a gap (comprising gaps between three side surfaces of the clamping groove and the side surfaces of the optical fiber support and gaps between the clamping surface of the clamping groove and the first end surface of the optical fiber support) between the clamping groove and the optical fiber support, and a sealing piece is formed after the first sealing glue is solidified so as to prevent cooling liquid from penetrating through the gap between the optical fiber support and the clamping groove.

But the gap between the clamping surface of the clamping groove and the first end surface of the optical fiber support (the surface facing the lens assembly in the optical fiber support) is injected with first sealing glue, and the first sealing glue possibly permeates into the first end surface of the optical fiber support and then permeates into the optical path between the lens assembly and the optical fiber support, so that the total optical path of the optical transceiver is affected.

In order to solve the problem, a shielding piece is arranged and used for shielding a gap between the lens assembly and the first end of the optical fiber support, and first sealing glue is dispensed on the outer side wall of the shielding piece, so that the distance between the first end face of the optical fiber support and the first sealing glue is far, and the first end face of the optical fiber support is not easy to be polluted by the first sealing glue.

Fig. 7 is a block diagram of a first optical transceiver component provided in accordance with some embodiments. Fig. 8 is an exploded view of a first optical transceiver component provided in accordance with some embodiments. Fig. 9 is a cross-sectional view of a first optical transceiver component provided in accordance with some embodiments. As shown in fig. 7, 8 and 9, in some embodiments, the first optical transceiver 901 includes a first lens assembly 911 and an optical fiber holder 912, one end of the first lens assembly 911 is provided with a package cavity 9112, one side of the package cavity 9112 is provided with an opening, one end of the optical fiber holder 912 is fixed with an optical fiber 9127, and the optical fiber holder 912 carries the optical fiber 9127 and inserts into the package cavity 9112 through the opening, so as to realize connection of the optical fiber holder 912 and the first lens assembly 911. After the optical fiber support 912 is inserted into the wrapping cavity 9112, the wrapping cavity 9112 wraps the optical fiber support 912, the first end face of the optical fiber support 912 is buried in the wrapping cavity 9112, and the first sealing glue is dispensed on the dispensing face 91124 of the wrapping cavity 9112, so that the distance between the first end face of the optical fiber support 912 and the first sealing glue is far, and the first end face of the optical fiber support 912 is not easy to be polluted by the first sealing glue. The first sealing glue is solidified to form a second sealing member, and the second sealing member is located around the side surface of the optical fiber support 912 and the dispensing surface 91124 of the package cavity 9112 to isolate the cooling liquid. After the optical fiber support 912 is inserted into the wrapping cavity 9112, a first sealing glue is dispensed on the dispensing surface 91124 of the wrapping cavity 9112, so that the first sealing glue seals all gaps between the wrapping cavity 9112 and the optical fiber support 912, the first sealing glue is piled up between the wrapping cavity 9112 and the optical fiber support 912, and a second sealing piece is formed after the first sealing glue is solidified, so that the connection tightness of the first lens assembly 911 and the optical fiber support 912 is ensured, and the purpose of preventing cooling liquid from penetrating is achieved.

After the optical fiber support 912 is inserted into the wrapping cavity 9112, four side surfaces of the optical fiber support 912 are respectively and correspondingly arranged with four side walls corresponding to the wrapping cavity 9112, a first end surface of the optical fiber support 912 is correspondingly arranged with a clamping wall of the wrapping cavity 9112, the clamping wall of the wrapping cavity 9112 is located in the deep part of the wrapping cavity 9112 and far away from the dispensing surface 91124 of the wrapping cavity 9112, namely, the first end surface of the optical fiber support 912 is located in the wrapping cavity 9112 and far away from the dispensing surface 91124 of the wrapping cavity 9112.

The first lens 9116 is disposed in the package cavity 9112, the first lens 9116 is disposed corresponding to the optical fiber support 912, the first lens 9116 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.

When the first lens assembly 911 is coupled to the circuit board 300, a suction nozzle is required to suck the first lens assembly 911, so that a gap exists 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 uneven or does not have a sufficiently large plane, the upper surface of the first lens assembly 911 has no place to place a suction nozzle. It is necessary to provide a large suction plane 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 enclosure 9112 is flush with the top surface of the area of the first lens assembly 911 other than the enclosure 9112, for providing a larger suction plane for the suction nozzle to hold the first lens assembly 911.

As shown in fig. 7, 8 and 9, an optical slot 9111 is disposed in a region of the first lens assembly 911 except for the package cavity 9112, an opening is disposed on a top surface (a plane facing away from the circuit board 300) of the optical slot 9111, a reflective surface 9115 is formed at the other end of a slot wall of the optical slot 9111, the reflective surface 9115 is disposed opposite to the first lens 9116, such that an optical signal emitted from the optical chip 303 (particularly, the optical emitting chip 3031) is reflected by the reflective surface 9115, the reflected optical beam is emitted by the first lens 9116, the first lens 9116 reflects the optical beam transmitted from the received optical fiber by the reflective surface 9115, and the reflected optical signal is incident on the optical chip 303 (particularly, the optical receiving chip 3032).

The wrap cavities 9112 wrap around the sides of the fiber optic bracket 912, increasing the thickness of the right side of the first lens assembly 911 (i.e., the end attached to the fiber optic bracket 912). Without increasing the thickness of the left side of the first lens assembly 911 (i.e., the end not connected to the optical fiber holder 912), a large difference in thickness ratio of the first lens assembly 911 is easily caused. It is thus necessary to increase the thickness of the left side of the first lens assembly 911, i.e., the thickness of the region of the first lens assembly 911 (the distance between the upper surface of the first lens assembly 911 and the lower surface of the first lens assembly 911) excluding the wrapping cavity 9112. The thickness of the region of the first lens assembly 911 other than the package cavity 9112 increases without changing the height of the position to which the first lens 9116 is mounted. In order for the reflective surface 9115 to reflect an optical signal to the first lens 9116, in some embodiments, the depth of the optical port slot 9111 increases. The depth of the optical port groove 9111 increases, and the distance between the opening of the optical port groove 9111 and the reflecting surface 9115 increases, reducing the penetration of the sealing member into the reflecting surface 9115 through the opening of the optical port groove 9111.

Illustratively, when the top surface of the area of the first lens assembly 911 other than the package cavity 9112 is higher than the top surface of the area of the first lens assembly 911 corresponding to the package cavity 9112, the depth of the optical aperture slot 9111 is less than 1mm; when 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, the depth of the optical slot 9111 is 1.8-2.2mm.

To prevent the cooling fluid from penetrating into the reflective surface 9115, in some embodiments, one end of the groove wall of the optical port groove 9111 is provided with a glue-separating protrusion, and a plurality of third seals are disposed on the glue-separating protrusion. The glue-isolating protrusions narrow the light-port grooves 9111 to form deep well grooves. Injecting a first sealing glue into the opening of the optical port slot 9111 to seal the opening of the optical port slot 9111, and isolating external cooling liquid from the reflecting surface of the optical port slot 9111 so as to prevent the cooling liquid from penetrating into the reflecting surface in the optical port slot 9111; because the first sealing glue is viscous, the first sealing glue can only cover the upper part of the deep well groove (namely the glue isolation protrusion of the light port groove 9111), and the air of the lower part of the deep well groove supports the first sealing glue, so that the first sealing glue cannot flow down onto the reflecting surface 9115, and the reflecting surface 9115 is isolated from external cooling liquid and is not influenced by the first sealing glue.

Because the top surface of the light port slot 9111 is provided with an opening, the plastic grinding tool can be conveniently subjected to demoulding treatment. In order to prevent the cooling liquid from penetrating into the reflecting surface 9115 through the opening of the light entrance slot 9111, in some embodiments, a blocking component is disposed on the top surface of the opening of the light entrance slot 9111, and the blocking component is fixed on the top surface of the light entrance slot 9111 to seal the opening of the light entrance slot 9111, thereby preventing the cooling liquid from penetrating through the opening of the light entrance slot 9111.

In some embodiments, the blocking assembly includes a sealing cover plate with one end capped on the fiber optic shelf and the other end capped on the light port channel to seal the opening of the light port channel 9111.

In some embodiments, the blocking assembly includes a blocking tab 913, the blocking tab 913 being secured to a top surface of the light port slot 9111 to seal the opening of the light port slot 9111.

In some embodiments, the side of the blocking piece 913 facing the light port slot 9111 is coated with a back adhesive, and the blocking piece 913 is adhered on the top surface of the light port slot 9111 by the back adhesive, so as to fix the blocking piece 913 on the top surface of the light port slot 9111.

In some embodiments, the material of the blocking piece 913 may be selected from, but is not limited to, polyimide.

The size of the blocking piece 913 is larger than the size of the opening of the light entrance slit 9111, so that the blocking piece 913 can completely block the opening of the light entrance slit 9111. After the opening of the light port slot 9111 is sealed by the baffle 913, a first sealing glue may be further added on the side surface of the baffle 913, that is, the first sealing glue is added at the junction between the baffle 913 and the surface of the first lens assembly 911, and a third sealing member is formed after the first sealing glue is solidified, so that the baffle 913 and the opening of the light port slot 9111 are sealed by the third sealing member, and the cooling liquid is reduced to permeate into the light port slot 9111, and the light port slot 9111 is isolated from the cooling liquid.

But, the blocking piece 913 is adhered to the opening of the optical slot 9111 only through the back adhesive, so that the adhesive force of the back adhesive is insufficient, resulting in poor connection stability between the blocking piece 913 and the opening of the optical slot 9111, and further resulting in poor connection tightness between the blocking piece 913 and the opening of the optical slot 9111, i.e. the blocking piece 913 cannot be completely sealed with the opening of the optical slot 9111. To achieve complete sealing between the blocking piece 913 and the opening of the light slot 9111, in some embodiments, a first sealant is added above and around the blocking piece 913. Namely, the first sealing glue is added above the blocking piece 913, at the joint of the blocking piece 913 and the surface of the first lens component 911 and on the surface of the first lens component 911, and after the first sealing glue is solidified, a third sealing piece is formed, and the blocking piece 913 and the opening of the optical port slot 9111 are completely sealed by the third sealing piece, so that the penetration of cooling liquid into the optical port slot 9111 is further reduced, and the isolation of the optical port slot 9111 from the cooling liquid is further ensured.

Since the first sealing glue may move, the movement of the first sealing glue may easily cause that the third sealing member after the curing of the first sealing glue cannot completely seal the blocking piece 913 and the opening of the optical slot 9111. To solve this problem, in some embodiments, a storage groove is disposed outside the light port groove 9111, and the light port groove 9111, the blocking piece 913, and a third seal are disposed in the storage groove, and the third seal is located on the top and the outer side wall of the blocking piece 913.

The third sealing member is located at the top and the outer side wall of the blocking piece 913, so as to realize stable connection between the blocking piece 913 and the storage groove. The third sealing member can be limited at a preset position by the object placing groove, so that the third sealing member is prevented from deviating from the preset position, the blocking piece 913 and the opening of the optical port groove 9111 are completely sealed, and the optical port groove 9111 is further isolated from the cooling liquid.

In some embodiments, an object placing groove is disposed on the outer side of the optical port groove 9111, the blocking piece 913 and the third sealing member are disposed in the object placing groove, and a glue isolation protrusion is disposed at one end of the groove wall of the optical port groove 9111. The third sealing piece can be fixed at a preset position by the object placing groove so as to realize the complete sealing of the blocking piece 913 and the opening, and avoid the infiltration of cooling liquid; the first sealing glue in the storage groove permeates into the glue isolation protrusion of the light port groove 9111, the first sealing glue is coated on the glue isolation protrusion, and the air of the lower part of the deep well groove supports the first sealing glue, so that the first sealing glue cannot flow down onto the reflecting surface 9115, and the reflecting surface 9115 is isolated from external cooling liquid and is not influenced by the first sealing glue.

The third sealing piece can be fixed at a preset position by the object placing groove so as to realize the complete sealing of the blocking piece 913 and the opening, and avoid the infiltration of cooling liquid; the first sealing glue in the object placing groove permeates into the first sealing glue of the light port groove 9111, the first sealing glue of the light port groove 9111 is coated on the glue isolation protrusion, and air at the lower part of the deep well groove supports the first sealing glue, so that the first sealing glue cannot flow down onto the reflecting surface 9115, and the reflecting surface 9115 is isolated from external cooling liquid and is not influenced by the first sealing glue.

In some embodiments, the optical module includes two sets of optical transceiver components that are staggered, and when the 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, and affects the optical fiber transmission. To solve this problem, the first lens assembly 911 is provided with an inclined surface 9113, and the inclined surface 9113 is inclined along the top surface of the first lens assembly 911 toward a side surface of the first lens assembly 911 remote from the optical fiber holder 912, i.e., 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, and the problem of optical fiber transmission caused by too small optical fiber radius is avoided.

After the first sealing glue seals the gap between the first lens assembly 911 and the circuit board 300, the optical module needs to be placed in a high temperature environment. After the first sealing glue seals the gap between the package cavity 9112 and the fiber optic bracket 912, the optical module also needs to be placed in a high temperature environment. The air in the cavity sealed by the high Wen Shidi sealing glue expands, and if no release hole exists, the expanded air pushes the uncured first sealing glue out of an air hole, so that the cooling liquid is permeated. Accordingly, the first lens assembly 911 is further provided with a vent 9119, and the vent 9119 is in communication with the housing cavity 9124 or the wrapping cavity 9112.

After the blocking piece 913 is attached to the first storage groove 9120, the first storage groove 9120 is filled with a first sealing glue, and the height of the first sealing glue is higher than that of the blocking piece, so that the first sealing glue is stacked on top of the blocking piece 913, and a third sealing piece is formed after the first sealing glue is solidified. The first storage groove 9120 defines a position of the third sealing member on the surface of the first lens assembly 911, so as to avoid the third sealing member from deviating from a preset position, so as to realize stable connection between the blocking piece 913 and the opening of the optical port groove 9111.

Because the first sealing glue is viscous, the first sealing glue can only be coated on the first glue isolation protrusion 9122 at the upper part of the deep well groove, and the air at the lower part of the deep well groove supports the first sealing glue, so that the first sealing glue cannot flow down onto the reflecting surface 9115, and the reflecting surface 9115 is isolated from external cooling liquid and is not influenced by the first sealing glue.
