ABSTRACT:
This invention provides an optical fiber connector having fiber termination assemblies each of which includes a member with a rearward barrel which is crimped over the optical fiber for retaining the fiber, and an external annular ridge defining shoulders used in holding the unit in the connector body, such as by retention fingers. Also included is a forward tubular part in which is a spherical lens centered in a recess, and an axial opening through which the fiber extends to a position adjacent the lens. A shoulder or transparent member may space the fiber end a predetermined distance from the spherical lens. The tubular part of one of the termination units may have an enlarged forward end receiving the forward end of the other for aligning the two and positioning the spherical lenses in spaced adjacency when the connector is mated.
