摘要： A method of manufacturing an optical fiber cable of the type which compri at least one cellular cylindrical structure of plastic material having a plurality of longitudinal bores housing individual optical fibers and filled with a viscous substance. The viscous substance is injected around the fibers under pressure as they pass along tubes which each have a gap of some length so that said viscous substance can enter the tubes. The optical fibers coated with viscous substance are made to protrude beyond the ends of said tubes. A thermoplastic material is simultaneously extruded through an annular orifice and around the optical fibers under a pressure which is sufficient to completely surround said coated optical fibers. The cylindrical structure thus obtained is rapidly cooled.

摘要： A multiple optical fibre cable in which the fibres can be used separately for long distance signal transmission comprises a central core round which the optical conductors are concentically disposed. Each optical conductor is constituted by an optical fibre protected by a first layer or covering of polyamide and a second layer or sheath of polyethylene. In order to avoid distortion of the optical fibre, the second layer or sheath is stretched. Application: Optical telecommunications cables.
