Abstract
The end region of an optical fiber cable is removed to expose the coated optical fiber and some of the cable reinforcing non-optical fibers. The coating is removed from the optical fiber which, when covered with glue or the like, is inserted into a hole in a ferrule. The hole is large enough to accept the uncoated fiber but not the coated fiber. Thus the ferrule is pushed onto the fiber until the coating is contacted insuring that no uncoated optical fiber is exposed. The uncoated length of the optical fiber is long enough to extend out the end of the ferrule remote from the cable and is removed flush with the end of the ferrule. The entire assembly, on an optical disconnect type, an end region of the cable, the non-optical fiber, the coated optical fiber extending between the cable and the ferrule and an end region of the ferrule adjacent the cable, are all encapsulated in an optical fiber connector which may be straight or angled at 45.degree. or more in the region between the cable and the ferrule. A strain relief boot may be molded to the cable and has a thumb pad aligned with a connector key of the ferrule whereby the connector key although not visible may be aligned with the …
