    Patent number: 6035086
    Abstract: An optical fiber cable has a kingwire (10) provided with inner and outer extruded layers (12, 18) of a thermoplastic elastomer. A plurality of optical fibers (14) are disposed on the outer surface (16) of the inner layer (12) and are embedded in the outer layer (18).

  • Optical fibre cable incorporating a stack of fibre ribbon elements
    Patent number: 5369720
    Abstract: In an optical fibre cable, the transmission package comprises a stack (11) of ribbon fibre elements (110) secured within a metal tube (12) by an adhesive (13). The adhesive has a peel strength sufficiently low to permit separation of the individual ribbon from the stack, e.g. to effect jointing operations. Advantageously the adhesive is foamed by injection of a gas during cable manufacture.
