Problems solved by technology
[0019] In the above sleeve unit 107, the transmission optical signal emitted from the light emitting element 161 is incident on the transmission side optical function part 181, and is sent out to the outside through the transmission side optical fiber 131. In the connection part 170 made of the same optical material as the other part, leakage to the outside from here causes the problem of light transmission loss.
The same problem of leakage occurs in the receiving optical signal incident on the receiving side optical function part 182 from the outside through the receiving optical fiber 132
[0020] In addition, in the above-mentioned sleeve unit 7, since the sending side optical function part 181 and the receiving side optical function part 182 are connected through the connecting part 170, a part of the sending optical signal emitted from the light emitting element 161 leaks to the connecting part 170, Reflected at the upper and lower interfaces between the joint and the outside air, as Figure 12B As shown by the arrow of , there is also a problem of crosstalk leaking to the light receiving element 162 of the office via the crosstalk path

Embodiment Construction
[0046] The best mode for carrying out the invention will be described with reference to the first embodiment shown in FIG. 1 . Figure 1B It is a front view of an optical coupling member having a coupling portion and an optical function portion, Figure 1A is the floor plan seen from above, Figure 1E is a side view seen from the side, Figure 1C , 1D is a stereogram.
[0047] In FIG. 1, 9 denotes an optical coupling member for bidirectional optical communication connection. The optical coupling member 9 is constituted by a cylindrical sender-side optical function part 81 made of translucent synthetic resin, a cylindrical receiver-side optical function part 82, and a connecting part 90 that mechanically combines these two optical function parts. . In addition, the connecting portion is used for mechanical coupling, but since it is integrally formed of the same material as the optical function portion, it is also optically coupled, resulting in reduced light transmission e...
