[0040] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. Now, in conjunction with the accompanying drawings, a preferred embodiment of the present invention is described in detail.

[0041] The embodiment of the present invention provides a mounting bracket 1000, such as Figure 1-Figure 4 As shown, the mounting bracket 1000 has a bearing wall 100 and a collimating lens 200. One side of the bearing wall 100 is provided with a Figure 2 The V-groove 110 is extended in the X direction (as shown in the figure), and the V-groove 110 is used to position the optical fiber 2000. The collimating lens 200 is arranged on one side of the V-groove 110 in the first direction and is aligned with the V-groove 110.

[0042] Since the mounting bracket 1000 of the present embodiment is integrally formed, after the mounting bracket 1000 is produced, the collimating lens 200 has been aligned with the V-groove 110 in the first direction, and there is no need to adjust and assemble the bearing wall 100 and the collimating lens 200. When it is necessary to couple the optical fiber 2000 and the collimating lens 200, it is only necessary to place the optical fiber 2000 in the V-groove 110, so that the optical fiber 2000 and the collimating lens 200 can be aligned in the first direction, and then the positions of the optical fiber 2000 and the collimating lens 200 are adjusted along the V-groove 110, and finally the optical fiber 2000 is fixed. Compared with the prior art, the mounting bracket 1000 provided in the present embodiment only needs to adjust the distance between the optical fiber 2000 and the collimating lens 200, and there is no need to adjust the angle, so the coupling method is simple, which can greatly reduce the time spent on coupling the optical fiber 2000 and the collimating lens 200. It can be seen that the use of the mounting bracket 1000 provided in the present embodiment can effectively improve the production efficiency of the wave splitting structure and the wave combining structure.

[0043] It is worth mentioning that the coupling of the collimating lens 200 in the prior art takes a lot of time, which is not only reflected in the need to adjust the angle of the collimating lens 200, but also in that after the angle of the collimating lens 200 changes, the relative position of the optical fiber 2000 and the collimating lens 200 will change, and it is necessary to compensate synchronously. In contrast, it can be more reflected that the coupling of the optical fiber 2000 and the collimating lens 200 in the prior art takes a lot of time, so that the production efficiency of the wave splitting structure and the wave combining structure is low. In the embodiment, the coupling method of the optical fiber 2000 and the collimating lens 200 is simple, which can greatly reduce the time spent on the coupling of the optical fiber 2000 and the collimating lens 200, thereby effectively improving the production efficiency of the wave splitting structure and the wave combining structure.

[0044] refer to Figure 1-Figure 4 In a specific embodiment, the other side of the bearing wall 100 has an installation area 9000 for installing the Z-Block 3000, and the V-shaped groove 110 and the installation area 9000 are in a second direction ( Figure 2 The mounting bracket 1000 also has a refractive structure 300, which is used to refract the light emitted from the collimating lens 200 to the Z-Block 3000, or to refract the light emitted from the Z-Block 3000 to the collimating lens 200.

[0045] Specifically, the bearing wall 100 of this embodiment can also be used for the installation of Z-Block 3000. The wave combining module and the wave splitting module do not need to be provided with a separate structure for the installation of Z-Block 3000, so that the produced wave splitting structure and wave combining structure can be more miniaturized. In order to allow the light emitted by the collimating lens 200 to be refracted to the Z-Block 3000, the mounting bracket 1000 of this embodiment also has a refractive structure 300. The refractive structure 300 is at least partially disposed on the side of the collimating lens 200 away from the V-groove 110. The refractive structure 300 is used to refract the light emitted by the collimating lens 200 to the Z-Block 3000, or to refract the light emitted by the Z-Block 3000 to the collimating lens 200.

[0046] More specifically, if the mounting bracket 1000 is applied to a wave splitting structure, Z-Block 3000 is a demultiplexer, and the refractive structure 300 is used to refract the light emitted from the collimating lens 200 away to the Z-Block 3000; if the mounting bracket 1000 is applied to a wave combining structure, Z-Block 3000 is a multiplexer, and the refractive structure 300 is used to refract the light emitted from the Z-Block 3000 to the collimating lens 200.

[0047] It should be noted that the mounting bracket 1000 of the present application is integrally formed, so the mounting bracket 1000 also has the refractive structure 300 after it is manufactured, which is beneficial to improving the production efficiency of the wave splitting structure and the wave combining structure.

[0048] It is worth mentioning that Z-Block3000 can be mounted using visual recognition, so that Z-Block3000 can be installed in the correct position relatively quickly, achieving the technical effect of improving the production efficiency of the split-wave structure and the combined-wave structure. Specifically, by photographing the Z-Block3000 and the mounting bracket 1000, the edge lines of the two are identified, and the edge lines are used to analyze the angle and distance to be adjusted. After the angle and distance compensation are completed, the Z-Block3000 can be mounted.

[0049] refer to Figure 1-Figure 4 In a specific embodiment, the V-shaped groove 110 is disposed on the bearing wall 100 in the third direction ( Figure 2 The third direction is perpendicular to the first direction and the second direction.

[0050] Specifically, in the final wave splitting structure and wave combining structure, a connector will be provided at the end of the optical fiber 2000 away from the collimating lens 200. If the optical fiber 2000 is biased toward one side of the mounting bracket 1000 in the third direction, it means that the connector will also be biased toward one side. Since the connector is not as small as the optical fiber 2000, the bias of the connector toward one side will cause the size of the wave splitting structure and the wave combining structure to become larger, which in turn will cause the optical device provided with the wave splitting structure and the wave combining structure to be larger in size.

[0051] refer to Figure 1-Figure 4 In a specific embodiment, the refractive structure 300 includes a first refractive surface 310, a second refractive surface 320 and a third refractive surface 330. The first refractive surface 310 is disposed on a side of the collimating lens 200 away from the V-groove 110, and is disposed at an angle of 45° with the first direction and the third direction. The second refractive surface 320 is disposed in the third direction of the first refractive surface 310, and is disposed at an angle of 45° with the second direction and the third direction. The third refractive surface 330 is disposed in the second direction of the second refractive surface 320, and is disposed at an angle of 45° with the first direction and the second direction.

[0052] When the mounting bracket 1000 is applied to the wave splitting structure, since the first refractive surface 310 is arranged on the side of the collimating lens 200 away from the V-groove 110, the outgoing light of the optical fiber 2000 will pass through the collimating lens 200 and be emitted to the first refractive surface 310. Moreover, since the first refractive surface 310 is arranged at a 45° angle to the first direction and the third direction, the first refractive surface 310 can refract the incident light to the third direction. Since the second refractive surface 320 is arranged in the third direction of the first refractive surface 310, the outgoing light of the first refractive surface 310 can be incident to the second refractive surface 320. Moreover, since the second refractive surface 320 is arranged at a 45° angle to the second direction and the third direction, the outgoing light of the first refractive surface 310 can be incident to the second refractive surface 320. Since the third refractive surface 330 is arranged at an angle of 45° to the first direction and the second direction, the second refractive surface 320 can refract the incident light to the second direction. Since the third refractive surface 330 is arranged in the second direction of the second refractive surface 320, the outgoing light of the second refractive surface 320 can be incident on the third refractive surface 330. Since the third refractive surface 330 is arranged at an angle of 45° to the first direction and the second direction, the third refractive surface 330 can refract the incident light to the first direction. Since the installation area 9000 for installing Z-Block3000 is located in the first direction of the third refractive surface 330, the outgoing light of the third refractive surface 330 can be incident on Z-Block3000.

[0053] When the mounting bracket 1000 is applied to a wave combining structure, the optical path is opposite to that when the mounting bracket 1000 is applied to a wave splitting structure. The light emitted from the Z-Block 3000 is refracted only by the third refractive surface 330 to the second refractive surface 320, and then refracted to the first refractive surface 310 via the second refractive surface 320, and then refracted only by the first refractive surface 310 to the collimating lens 200, and then passes through the collimating lens 200 to be incident on the optical fiber 2000.

[0054] refer to Figure 1-Figure 4 In a specific embodiment, the second refractive surface 320 and the third refractive surface 330 are both located on one side of the bracket in the third direction. The reason is that when the Z-Block 3000 is used as a multiplexer, the position of its outgoing light is located on one side in the third direction, and when the Z-Block 3000 is used as a demultiplexer, the position of its incident light is located on one side in the third direction. Therefore, in this embodiment, the second refractive surface 320 and the third refractive surface 330 are arranged on one side of the bracket in the third direction, which is conducive to the miniaturization of the mounting bracket 1000. The miniaturization of the mounting bracket 1000 is conducive to reducing the volume of optical devices with a wave splitting structure and a wave combining structure.

[0055] refer to Figure 1-Figure 4 In some embodiments, a groove 120 is further provided on the bearing wall 100 , and the groove 120 is located between the V-shaped groove 110 and the collimating lens 200 . The width of the groove 120 is greater than the width of the V-shaped groove 110 , and the depth of the groove 120 is greater than the depth of the V-shaped groove 110 .

[0056] Specifically, since the light emitted by the optical fiber 2000 is divergent light, in order to avoid the divergent light emitted by the optical fiber 2000 being blocked, this embodiment sets a groove 120 between the V-groove 110 of the optical fiber 2000 and the collimating lens 200, and the width of the groove 120 is greater than the width of the V-groove 110, and the depth of the groove 120 is greater than the depth of the V-groove 110.

[0057] refer to Figure 1-Figure 4 In some embodiments, the mounting bracket 1000 further comprises a plurality of converging lenses 400, which are arranged in an array along a third direction between the mounting area 9000 and the refractive structure 300; the third direction is perpendicular to the first direction and the second direction. Specifically, the converging lenses 400 can converge the incident light beam to achieve the beneficial effect of improving the quality of the light beam.

[0058] It should be noted that the mounting bracket 1000 of the present application is integrally formed, so the mounting bracket 1000 also has the converging lens 400 after it is manufactured, which is beneficial to improving the production efficiency of the wave splitting structure and the wave combining structure.

[0059] refer to Figure 1-Figure 4 In a specific embodiment, the mounting bracket 1000 further has a fourth refractive surface 500, which is disposed on a side of the plurality of converging lenses 400 away from the mounting area 9000, and the fourth refractive surface 500 is disposed at an angle of 45° with the first direction and the second direction.

[0060] Specifically, the PD chip of the wave splitting structure is mounted on the circuit board. If the PD chip is directly arranged in the emission direction of the converging lens 400, the optical fiber 2000 will be perpendicular to the circuit board, which will cause the size of the wave splitting structure to be larger. Similarly, the LD chip of the wave combining structure is mounted on the circuit board. If the converging lens 400 is directly located in the emission direction of the LD chip, the optical fiber 2000 will be perpendicular to the circuit board, which will cause the size of the wave combining structure to be larger.

[0061] By implementing this embodiment, a fourth refractive surface 500 is added. Since the fourth refractive surface 500 is arranged on the side of the plurality of converging lenses 400 away from the installation area 9000, and the fourth refractive surface 500 is arranged at an angle of 45° to the first direction and the second direction, the fourth refractive surface 500 can refract the light emitted from the converging lens 400 or the light emitted from the LD chip, so that the optical fiber 2000 can be parallel to the circuit board, thereby reducing the volume of the wave splitting structure and the wave combining structure.

[0062] It should be noted that the mounting bracket 1000 of the present application is integrally formed, so the mounting bracket 1000 has the fourth refractive surface 500 after being manufactured, which is beneficial to improving the production efficiency of the wave splitting structure and the wave combining structure.

[0063] It is worth mentioning that the mounting bracket 1000 shown in the present application is manufactured by a molding process, and it is only necessary to first make a mold according to the structure of the mounting bracket 1000 that is pre-conceived, and then melt the material and inject it into the mold, and then cool and anneal and demold it to obtain an integrally molded mounting bracket 1000. Since the mold can be recycled, the production cost can be compressed to a very low level as long as it is mass-produced.

[0064] The embodiment of the present invention also provides a wave splitting structure, such as Figure 1-Figure 4 As shown, the wave splitting structure includes a mounting bracket 1000, an optical fiber 2000, a Z-Block 3000 and a circuit board. The mounting bracket 1000 is the mounting bracket 1000 shown in the above embodiment. The optical fiber 2000 is installed in the V-shaped groove 110 of the mounting bracket 1000, and the Z-Block 3000 is installed on the side of the bearing wall 100 of the mounting bracket 1000 that is away from the V-shaped groove 110. A PD chip is provided on the circuit board, and the PD chip is located on the outgoing light path of the Z-Block 3000.

[0065] Since the mounting bracket 1000 of the present embodiment is integrally formed, after the mounting bracket 1000 is produced, the collimating lens 200 has been aligned with the V-groove 110 in the first direction, and there is no need to adjust and assemble the bearing wall 100 and the collimating lens 200. When it is necessary to couple the optical fiber 2000 and the collimating lens 200, it is only necessary to place the optical fiber 2000 in the V-groove 110, so that the optical fiber 2000 and the collimating lens 200 can be aligned in the first direction, and then the positions of the optical fiber 2000 and the collimating lens 200 are adjusted along the V-groove 110, and finally the optical fiber 2000 is fixed; compared with the prior art, the mounting bracket 1000 provided in the present embodiment only needs to adjust the distance between the optical fiber 2000 and the collimating lens 200, and there is no need to adjust the angle, so the coupling method is simple, which can greatly reduce the time spent on coupling the optical fiber 2000 and the collimating lens 200. It can be seen that the use of the mounting bracket 1000 provided in the present embodiment can effectively improve the production efficiency of the split wave structure.

[0066] The embodiment of the present invention also provides a wave combining structure, such as Figure 1-Figure 4 As shown, the wave combining structure includes a mounting bracket 1000, an optical fiber 2000, a Z-Block 3000 and a circuit board, and the mounting bracket 1000 is the mounting bracket 1000 shown in the above embodiment. The optical fiber 2000 is installed in the V-shaped groove 110 of the mounting bracket 1000, and the Z-Block 3000 is installed on the side of the bearing wall 100 of the mounting bracket 1000 that is away from the V-shaped groove 110. An LD chip is arranged on the circuit board, and the Z-Block 3000 is located on the outgoing light path of the LD chip.

[0067] Since the mounting bracket 1000 of the present embodiment is integrally formed, after the mounting bracket 1000 is produced, the collimating lens 200 has been aligned with the V-groove 110 in the first direction, and there is no need to adjust and assemble the bearing wall 100 and the collimating lens 200. When it is necessary to couple the optical fiber 2000 and the collimating lens 200, it is only necessary to place the optical fiber 2000 in the V-groove 110, so that the optical fiber 2000 and the collimating lens 200 can be aligned in the first direction, and then the positions of the optical fiber 2000 and the collimating lens 200 are adjusted along the V-groove 110, and finally the optical fiber 2000 is fixed; compared with the prior art, the mounting bracket 1000 provided in the present embodiment only needs to adjust the distance between the optical fiber 2000 and the collimating lens 200, and there is no need to adjust the angle, so the coupling method is simple, which can greatly reduce the time spent on coupling the optical fiber 2000 and the collimating lens 200. It can be seen that the use of the mounting bracket 1000 provided in the present embodiment can effectively improve the production efficiency of the combined wave structure.
