  • Publication number: 20040121646
    Abstract: The present disclosure relates to connector assemblies for use with multi-conductor connection cables. More specifically, the present disclosure relates to a flexible angle configurable boot assembly for use with a multi-conductor cable where the angle configurable boot defines an area for receiving the multi-conductor cable for positioning the cable at a known angle and/or orientation with respect to the flexible angle configurable boot in at least one location, and where the angle configurable boot may be coupled to the cable connector in one or a plurality of alternate orientations. The present disclosure also relates to a process for installing such a flexible angle configurable boot assembly.

  • Patent number: 5892871
    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.

  • Patent number: 5703981
    Abstract: A termination ferrule body with a ferrule for an optical fiber is molded directly about the optical fiber employing a mold insert defining a hole in the insert that precisely locates the optical fiber in the center of the end of the ferrule.
