一种光纤连接器，包括一插头和一插座，采用由插头纤维弯曲所提供的弹力而在纤维对齐槽中的纤维接合处上保持一连续的挤压力。插头具有一用于固定插头纤维的夹头，以及一卡到夹头上的罩壳，并且插头纤维在罩壳内大体上直线延伸。罩壳具有一提供进入插头纤维端部的通道，以及有选择地盖住槽的滑门。插座包括一外壳和另一纤维夹头用于固定插座纤维，并且一突起部或指状部安装到插座纤维夹头上，该突起部具有纤维对齐槽。指状部在插座外壳中定向为，当插头插入插座时，指状部相对插头轴线成一斜角地伸过罩壳中的槽。在这种情况下，当插头插入时，插头纤维的端部滑入指状部中的纤维对齐槽，并且与插座纤维的端面接触。连续的插入造成插头纤维的弯曲以获得挤压负荷。插头门可具有凸轮形表面，它们可由插座门上的对应表面驱动。连接器可用于同时互连多对纤维，或将一根纤维端接到一有源光学装置上。 A receptacle for terminating an optical fiber at an active device such as a photodetector or solid-state light source. The receptacle includes a housing, a termination fixture and an active device. The housing has an opening for receiving the terminal portion of an optical fiber, a door located at the opening, biased to a closed position and having a latch for releasably receiving an optical fiber plug, and a removable plate allowing access to an interior of the housing. The termination fixture and the active device may be mounted to a common substrate attached to an interior portion of the housing. The termination fixture includes a base and a projection attached to the base proximate a light-transmitting portion thereof, the projection having a fiber-receiving groove directed toward a fiber stop surface located on the light-transmitting portion of the base. The base can have a lens integrally molded with the light-transmitting portion. The active device is positioned with respect to the termination fixture to receive light from, and/or transmit light to, any fiber whose terminal portion is located in the V-groove and abutting the fiber stop. An optional optical plate may be used to adjust the optical characteristics of the termination fixture.
