  • Patent number: 4832442
    Abstract: A long-distance transmission fiber optic cable system suitable for outdoor aerial installation includes a continuous length of non-metallic messenger cable with an aramid fiber, tension load bearing core and a predetermined tension load bearing strength and a polymer outer jacket adapted for outdoor exposure and a continuous length of fiber optic cable, longer than the continuous length of non-metallic messenger cable and including a plurality of fiber optic waveguides within an outer polymer jacket adapted for outdoor exposure and having a tension load bearing strength less than the predetermined tension load bearing strength, and preferably non-metallic, helically wound around the continuous length of the non-metallic cable so as to permit free axial movement. Continuous lengths of 40,000 feet or more of the preferred non-metallic messenger cable and fiber optic cables suitable for outdoor use have been made.

  • Patent number: 4733464
    Abstract: The present invention provides a connector for terminating and connecting a portion of a cable. The connector is used with a cable having a core comprising synthetic filaments, a polymeric sheath covering the core, an inner sheath comprising braided metallic filaments covering the polymeric sheath, and a polymeric outer jacket covering the inner sheath. Portions of the jacket and the inner sheath are stripped proximate the portion of a cable to be terminated to provide an exposed polymeric sheath and core portion of a first predetermined length and an exposed inner sheath portion of a second predetermined length. A generally tubular outer sleeve, having an axial length at least slightly greater than the length of exposed braided metallic filaments, is positioned so that either sleeve end extends beyond the exposed portion of the braided metallic sheath.
