Abstract
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.
