Abstract

In an optical fibre cable comprising an assembly of transmission units, either all optical fibre waveguide units or including electrical conductor modules, at least three transmission units of circular cross- section and of equal external diameter, at least one of which is an optical fibre waveguide unit (15), are helically laid around a central reinforcing member (17), with or without intervening units, preferably conductor modules (16), which may be of smaller diameter, and possibly with one or more outer helically laid layers of conductor modules, the whole assembly being contained in a closely fitting tubular jacket (18), which may have reinforcing members embedded therein. Each optical fibre unit 15 consists of a plastic sheath having a circular cylindrical external surface, with one or more bores containing loose optical fibres, and compression resistant reinforcing members embedded in the sheath. Each electrical conductor module may consist of any desired number of wires, with or without a containing sheath. <IMAGE>
