Fiber optic connector

Abstract

A fiber optic cable connector assembly for precise end-to-end mating of two fiber optic cables in a low loss light transmitting relation. An interconnect housing has loosely disposed and captured therein a floating spring metal sleeve of non-circular, multi-lobed cross-section having flared ends adapted to capture the sleeve within the housing and to guide opposing cylindrical ferrules, each containing and supporting a respective fiber optic cable, into resiliently held facing relationship within the sleeve. Each ferrule can include an oversized end member having a central aperture containing the end of the optical fiber, the outer periphery of the end member engaging the surrounding sleeve to coaxially align the optical fiber. A rearward cylindrical wall of the ferrule also engages the sleeve and prevents off-axis cocking of the ferrule in the sleeve. Means are provided to suspend the cable in the connector body without potting and to secure the outer jacket of the cable at its point of entry into the connector body. The end face of the ferrule is provided with an overflow well for receiving excess adhesive used to secure the end member on this face of the ferrule. Each cable is secured to a connector body which is attachable to the interconnect housing in a manner to minimize non-axial forces which could cause optical misalignment of the fiber ends.
