A communication cable (10) comprises optical fibres (24) and/or metal conductors (20) for the transmission of information, and a tensile member, the tensile member comprising a steel strand and synthetic material. The steel strand has a modulus of elasticity of at least 140 000 N/mm.sup.2. The steel strand comprises a core wire (12) and one layer of layer wires (14) surrounding the core wire. A contact is provided between the layer wires and the core wire. The interstices between the layer wires and the core wire are filled with a first synthetic material (13) having a melting-point above 150.degree. C. The steel strand is covered by a layer of a second synthetic material (16). The filling with the first synthetic material and the covering by a layer of a second synthetic material is such that watertightness is obtained in the longitudinal direction of the tensile member.
