[0059] The embodiments of the utility model are described in detail below, and the embodiments described with reference to the drawings are exemplary. The following refers to the drawings Figures 1-9 The optical splitting module 100 according to the embodiments of the utility model is described. The optical splitting module 100 comprises: an optical splitter 10 and a first output optical connector 21.

[0060] As shown in Figure 1 The optical splitter 10 has a plurality of optical splitter output light paths 11. The first output optical connector 21 is directly connected to the optical splitter 10. The first output optical connector 21 has at least one connector output light path. The connector output light path is in communication with at least one of the plurality of optical splitter output light paths 11.

[0061] Optionally, in combination with Figure 1 The optical splitter 10 has a plurality of optical splitter output light paths 11. The plurality of optical splitter output light paths 11 of the optical splitter 10 are integrated in the optical splitter 10. The plurality of optical splitter output light paths 11 can output optical signals with the same light intensity or output optical signals with different light intensities. The connector output light path in the first output optical connector 21 is opposite to the optical splitter output light path 11 in the optical splitter 10. The connector output light path is in communication with at least one of the plurality of optical splitter output light paths 11. The optical signals in the optical splitter output light path 11 are transmitted to the connector output light path. The first output optical connector 21 is adapted to output the optical signals output by the optical splitter 10.

[0062] It can be understood that the specific arrangement of the optical splitter 10, the first output optical connector 21, the plurality of optical splitter output light paths 11, and the connector output light path can be set according to actual requirements to better meet actual applications.

[0063] The embodiment of the utility model discloses a light splitting module 100, through setting up multiple splitter output light path 11 in the splitter 10, and make the first output light connector 21 with splitter 10 direct connection, effectively improve the integration of light splitting module 100, simplify the structure of light splitting module 100, reduce the volume of light splitting module 100, improve the assembly efficiency and the convenience of use of light splitting module 100.

[0064] As Figure 1 Shown, in some optional embodiments of the utility model, splitter 10 includes: light splitting piece 13, light splitting piece 13 includes multiple splitter output light path 11.

[0065] For example, in Figure 1 The example, light splitting piece 13 has multiple splitter output light path 11 adjacent to one end of first output light connector 21, and multiple splitter output light path 11 is spaced apart adjacent to one end of first output light connector 21.

[0066] Light splitting piece 13 includes multiple splitter output light path 11, can integrate multiple splitter output light path 11 with splitter 10, improve the integration of splitter 10, thereby improve the integration of light splitting module 100 as a whole.

[0067] In some optional embodiments of the utility model, as Figure 1 Shown, splitter 10 also includes: shell 12, light splitting piece 13 is located in shell 12, and first output light connector 21 is directly connected with shell 12.

[0068] Light splitting piece 13 is located in the inside of shell 12, and first output light connector 21 is connected with one end of shell 12 adjacent to each other. Light splitting piece 13 is located in shell 12, and first output light connector 21 is directly connected with shell 12, can integrate first output light connector 21, light splitting piece 13 with splitter 10, improve the connection strength of first output light connector 21 and splitter 10, avoid realizing intercommunication through optical fiber or wire harness, reduce the volume of splitter 10, simplify the structure of splitter 10, optimize the structure of light splitting module 100, improve the integration of light splitting module 100.

[0069] In some optional embodiments of the utility model, as Figure 1 And Figure 3 Shown, first output light connector 21 and shell 12 are integrally formed. First output light connector 21 and shell 12 can be integrally machined. Thus, the structural strength of first output light connector 21 and shell 12 can be improved, the production efficiency of light splitting module 100 can be improved, and the production cost can be reduced.

[0070] Of course, in some other optional embodiments of the utility model, the first output optical connector 21 is detachably connected or fixedly connected with the shell 12. In the manufacturing process, the first output optical connector 21 and the shell 12 can be two components independent of each other. Thus, the maintenance and replacement of the first output optical connector 21 and the optical splitter 10 can be facilitated, the processing technology of the optical splitting module 100 is reduced, and the cost is reduced.

[0071] In some embodiments of the utility model, as shown in Figure 1 and Figure 3 , the first output optical connector 21 is provided with a first light-transmitting structure 211, and the first light-transmitting structure 211 covers the plurality of optical splitter output light paths 11.

[0072] For example, in the examples of Figure 1 and Figure 3 , the first light-transmitting structure 211 is opposite to the plurality of optical splitter output light paths 11 in the optical splitting piece 13, and the first light-transmitting structure 211 covers the first light-transmitting structure 211 at one end of the optical splitter output light path 11 adjacent to the first output optical connector 21. Here, the coverage can be understood as that the optical signal output through the optical splitter output light path 11 enters the first output optical connector 21 through the first light-transmitting structure 211. The first light-transmitting structure 211 is adapted to transmit the optical signals output by the plurality of optical splitter output light paths 11 to the connector output light path in the first output optical connector 21 and output to the outside of the optical splitting module 100 through the connector output light path. The first light-transmitting structure 211 is arranged at one end of the first output optical connector 21 adjacent to the optical splitting piece 13.

[0073] The first light-transmitting structure 211 covers the plurality of optical splitter output light paths 11, which can make the connector output light path in the first output optical connector 21 sufficiently receive the optical signals output from the optical splitter output light path 11, reduce the loss of optical energy, and improve the output power and stability of the optical splitting module 100.

[0074] In some embodiments of the utility model, as shown in Figure 1 and Figure 3 , a plurality of first light-transmitting protrusions are arranged on the side surface of the first light-transmitting structure 211 away from the optical splitter output light path 11, and the plurality of first light-transmitting protrusions correspond to the plurality of optical splitter output light paths 11 one by one.

[0075] For example, in the examples of Figure 1 and Figure 3 , the plurality of first light-transmitting protrusions are arranged on the side surface of the first light-transmitting structure 211 away from the optical splitter 10, and the plurality of first light-transmitting protrusions are adapted to expand and converge the optical signals output by the plurality of optical splitter output light paths 11.

[0076] The side surface of the first light-transmitting structure 211 away from the light paths 11 of the light splitter is provided with a plurality of first light-transmitting protrusions corresponding to the light paths 11 of the light splitter respectively, which can focus or collimate the light emitted by the light paths 11 of the light splitter and transmit the light to the connector light path in the first output light connector 21 to the greatest extent, thereby reducing the loss of light energy and improving the tolerance of the light splitting module 100 to harsh environments.

[0077] Optionally, the first light-transmitting protrusion is formed in a convex spherical shape away from the corresponding light path 11 of the light splitter.

[0078] For example, a plurality of convex spherical first light-transmitting protrusions are formed on the side surface of the first light-transmitting structure 211 away from the light paths 11 of the light splitter, which can better collect the light emitted by the light paths 11 of the light splitter and transmit the light to the connector light path in the first output light connector 21.

[0079] The first light-transmitting protrusion is formed in a convex spherical shape away from the corresponding light path 11 of the light splitter, which can further improve the utilization rate of the first output light connector 21 to the light emitted by the light paths 11 of the light splitter.

[0080] In some embodiments of the utility model, as shown in Figure 2 The connector light path is formed as an opening through the first output light connector 21, and the light paths 11 of the light splitter are opposite to the opening.

[0081] For example, in the example of Figure 2 The opening passes through one end of the first output light connector 21 adjacent to the light splitter 10, and the opening is aligned with the light paths 11 of the light splitter 10. Thus, the connector light path is formed as an opening through the first output light connector 21, and the light paths 11 of the light splitter are opposite to the opening, so that the light paths 11 of the light splitter are directly opposite to the connector light path in the first output light connector 21, ensuring that the light signals emitted by the light paths 11 of the light splitter can pass through the first output light connector 21, so that the light signals can be transmitted between the light paths 11 of the light splitter and the connector light path only through the air medium.

[0082] In some embodiments of the utility model, as shown in Figures 1-4 The light splitting module 100 further comprises a first input light connector 31 provided with at least one connector input light path, and the light splitter 10 is provided with a light splitter input light path, and the connector input light path is opposite to the light splitter input light path.

[0083] The connector input light path in the first input light connector 31 is opposite to the beam splitter input light path in the beam splitter 10, facilitating the transmission of the optical signal between the connector input light path and the beam splitter input light path, and improving the transmission efficiency.

[0084] In some optional embodiments of the utility model, as shown in Figure 1 and Figure 3 , the first input light connector 31 is provided with a second light transmission structure 311, and the second light transmission structure 311 covers at least one beam splitter input light path.

[0085] Optionally, the second light transmission structure 311 in the first input light connector 31 is opposite to at least one beam splitter input light path in the beam splitter 13, and the second light transmission structure 311 covers at least one beam splitter input light path, and the second light transmission structure 311 is suitable for transmitting the optical signal to be split input by the connector input light path in the first input light connector 31 to at least one beam splitter input light path in the beam splitter 13.

[0086] The second light transmission structure 311 covers at least one beam splitter input light path, which can make the beam splitter input light path sufficiently receive the optical signal to be split input by the connector input light path in the first input light connector 31, reduce the loss of optical energy, and improve the output power and stability of the beam splitting module 100.

[0087] As shown in Figure 1 and Figure 3 , in some optional embodiments, the second light transmission structure 311 is provided with a second light transmission protrusion on the side surface away from the beam splitter input light path, and the second light transmission protrusion is opposite to the end of the beam splitter input light path away from the first output light connector 21.

[0088] In some optional embodiments, the second light transmission protrusion is arranged on the side surface of the second light transmission structure 311 away from the beam splitter 10 along the beam splitting module 100, and the second light transmission protrusion protrudes towards the direction away from the beam splitter input light path, and the second light transmission protrusion is opposite to the end of the beam splitter input light path away from the first output light connector 21, wherein the second light transmission protrusion is suitable for converging the optical signal to be split input by the first input light connector 31. The second light transmission structure 311 is provided with a second light transmission protrusion on the side surface away from the beam splitter input light path, and the second light transmission protrusion is opposite to the end of the beam splitter input light path away from the first output light connector 21, which can make the optical signal to be split input by the first input light connector 31 focus through the second light transmission structure 311, collect the light rays to the maximum extent, improve the input power of the first input light connector 31, improve the output power of the beam splitting module 100, and improve the tolerance of the beam splitting module 100 to harsh environments.

[0089] In some optional embodiments of the utility model, at least one of the first output optical connector 21 and the first input optical connector 31 is a light-transmitting piece. Alternatively, part of at least one of the first output optical connector 21 and the first input optical connector 31 can also be a light-blocking piece.

[0090] For example, optionally, when the first output optical connector 21 is provided with the first light-transmitting structure 211, the first light-transmitting structure 211 covers the plurality of beam splitter output light paths 11, and the first input optical connector 31 is provided with the second light-transmitting structure 311, the second light-transmitting structure 311 covers at least one beam splitter input light path, the first output optical connector 21 and the first input optical connector 31 are both light-transmitting pieces. Thus, the use of external light by the beam splitting module 100 can be increased.

[0096] In some embodiments of the utility model, as shown in Figure 3 and Figure 4 , the light splitting piece 13 is a planar lightwave circuit piece or a fused biconical taper fiber piece. However, it is not limited thereto.

[0097] The planar lightwave circuit is also called PLC (planar lightwave circuit). The planar lightwave circuit is a micro optical path made by micro processing technologies such as photoetching and etching. The fused biconical taper fiber is a fiber group made by heating and stretching multiple optical fibers into a taper. Thus, the light splitting piece 13 is a planar lightwave circuit piece or a fused biconical taper fiber piece, which can reduce the manufacturing cost of the light splitting piece 13, make the structure of the light splitting piece 13 simple, realize passive distribution of optical power, and improve the working precision, working efficiency and reliability of the light splitting module 100.

[0098] As shown in Figure 4 , when the light splitting piece 13 is a fused biconical taper fiber piece, the first output optical connector 21 and the first input optical connector 31 are respectively provided with at least one groove, and the end of the fused biconical taper fiber is fitted in the groove.

[0099] Optionally, in combination with Figure 4 , the groove includes a first groove and a second groove. When the light splitting piece 13 is a fused biconical taper fiber piece, the first input optical connector 31 is provided with at least one first groove at one end adjacent to the light splitter 10, and the first output optical connector 21 is provided with multiple second grooves at one end adjacent to the light splitter 10 along the second direction B. The end of the fused biconical taper fiber adjacent to the first input optical connector 31 is fitted in the first groove, and the end of the fused biconical taper fiber adjacent to the first output optical connector 21 is fitted in the multiple second grooves.

[0100] Thus, the first output optical connector 21 and the first input optical connector 31 are respectively provided with at least one groove, and the end of the fused biconical taper fiber is fitted in the groove, which can improve the connection strength between the light splitting piece 13 and the first input optical connector 31 and the first output optical connector 21, avoid the light splitting piece 13 from falling off, and improve the stability and reliability of the light splitting piece 13.
