  • Fiber optic cable system including main and drop cables and associated fabrication method
    Patent number: 5528718
    Abstract: A fiber optic cable system, such as a preterminated fiber cable, includes a main cable and one or more drop cables connected to the main cable at spaced apart locations along the main cable. The drop cable is spliced to the main cable using a splice closure including a fiber guide that secures spliced together end portions of the respective fibers in a longitudinally extending direction and devoid of any slack coils of optical fibers. Accordingly, the overall diameter of the splice closure is relatively small thereby permitting the cable system to be stored on a reel and to be readily placed within small diameter conduits. The splice closure includes a heat recoverable housing surrounding the fiber guide. Cable sheath end portions are sealed by melting C-shaped bodies of heat flowable material positioned adjacent cable sheath end portions.
    Type: Grant

    Date of Patent: June 18, 1996
    Assignee: Raychem Corporation
    Inventors: Craig D. Ray, Carney P. Claunch, II, Terrance D. Hunsinger, Julian S. Mullaney, Michael L. Randolph, Robert G. Sember, James R. Shaw, Amanda C. Smith, Stephen E. Wald
