Abstract
In a hermaphroditic connector (20), an optical fiber cable (24) extends through a cap (46) into a tapered passageway of a flanged bushing. Optical fibers extend through a bore in a wedge (65) having a truncated conical shape and being received in the bushing. Portions of non-metallic filamentary strength member (28) of the cable are captured between surfaces of a wall of the tapered passageway and the wedge which are substantially smooth to avoid damage to the strength members. Forces applied to the cable cause the wedge to be seated further in the bushing. The included angle between diametrically opposite lines on the wedge surface that lie in a plane passing through the longitudinal axis of the wedge enhances the locking features. The fibers also extend through a retention nut (70) which is turned threadably over a portion of the bushing and each fiber is connected to a plug (94) mounted adjacent to an end of the connector with one plug being received in an alignment sleeve (130). A retainer (140) is disposed over the sleeve and the other plug and includes alignment posts (145--145). When another connector is assembled hereto, a plug of the other connector is received in the unus…
