Abstract
A pair of interengageable connectors for interconnecting optical fiber tape or ribbon cables which have a plurality of parallel optical fibers within a relatively thin and wide covering. Each connector has a ferrule formed by semicylindrical elements with engaging and axially extending planar faces. One end of the elements is a coupling face, and the planar faces have grooves extending axially from the coupling face for receiving the fibers with the covering removed and a recess remote from the coupling face for receiving the fibers with the covering thereon. The elements are held together by a sleeve which extends from at or adjacent the coupling face toward the other end of the ferrule. A ring nut with teeth for engaging corresponding teeth of the other connector encircles the sleeve and the ferrule and is slidable axially with respect thereto. A spring urges the ring nut toward the end of the ferrule remote from the coupling face. The assembled elements have axially extending holes receiving alignment pins.
