Abstract
A connector for interconnecting the ends of two optical fiber cables to provide accurate alignment of the optical fibers free of stress from the mechanical linkage of the respective cables. The sheath at the adjoining end of each cable is split in two and separated to expose the optical fiber. The split ends of the sheath are inserted in separate diverging holes in a mounting ferrule while the exposed optical fiber is inserted in a central bore between the diverging holes. The sheath ends are anchored by cementing the ends in the holes. Only the very outer end of the exposed optical fiber is anchored by cement in the ferrule to fix the alignment of the fiber. The rest of the exposed fiber between the anchored outer end and the point at which the sheath is split is bowed slightly to relieve any tension on the fiber. The ends of the cables are joined by mounting the ferrules in a common connector body with the outer ends of the fibers held in abutting axial alignment.
