Optical communication apparatus having coupler and supporting member connected together

摘要

Optical communication apparatus includes a PCB, a photoelectric unit electrically connected to the PCB, a supporting member positioned on the PCB, a coupler supported on the supporting member, and an optical fiber unit. The coupler optically couples the photoelectric unit to the optical fiber unit. The supporting member defines a through stepped hole having a larger first hole and a smaller second hole. The supporting member includes a step portion between the first hole and the second hole. The second hole is closer to the PCB than the first hole. One of the supporting member and the coupler defines a plurality of wedged positioning holes, the other of the supporting member and the coupler comprises a plurality of wedged positioning poles corresponding to positioning holes, and the coupler is connected to the supporting member by inserting the positioning poles into the corresponding positioning holes.
