A communication cable (10) comprises optical fibres (16) for the transmission of information and a tensile member for preventing the optical fibres (16) from being put under load. The tensile member is a single steel wire (12) or an open steel strand of two to five steel wires (24, 26, 30). The tensile member is covered with a synthetic coating (14). The adhesion between the tensile member and the synthetic coating is so strong that in a standard adhesion test only small strips of synthetic coating with a length less than 1 cm can be pulled off manually from the coated tensile member so that the production of hydrogen is limited. <IMAGE> |
