摘要:
An optical transmitter-receiver module has a light-emitting element for emitting transmission signal light and a light-receiving element for receiving reception signal light, and performs both transmission of the transmission signal light and reception of the reception signal light by means of a single-core optical fiber. A light-emitting device 91 having the light-emitting element is covered with an upper shield plate 93 and a lower shield plate 94 each provided by a conductive metal plate while being held between the plates. Connection terminals 95 and 96 of the upper shield plate 93 and the lower shield plate 94, which are extended in a direction in which lead terminals 99 of the light-emitting device 91 are extended, are connected to grounding terminals included in the lead terminals 99.

The connector of the present invention is capable of insertion and removal of a plug having an unmoving section and a moving section that is movable with respect to the unmoving section. The connector includes a plug fixing member for fixing the unmoving section by movement of the moving section and the unmoving section in a plug insertion direction along with insertion of the plug into the connector, and for releasing the unmoving section by shifting of the moving section with respect to the unmoving section in a plug removal direction. On this account, it is possible to fix and release the plug according to the movement of the moving section of the plug.
