  • 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.
