The invention relates to an electrical overhead cable rope comprising an integrated optical communication lead (13), in which metallic wire elements (14, 15, 16) surround a tube (1) or noble steel, in which at least one optical waveguide (2) is contained. Corrosion of the wire elements of the overhead cable rope is prevented by providing a tube (1) of noble steel having applied to it a water-tight coating which establishes a continuous electrically conducting connection between the tube of noble steel and the wire elements (14, 15, 16) surrounding it.

The invention relates to a method of producing an optical cable in which at least one optical waveguide fed forward from a supply reel is provided with a loosely surrounding jacket by means of extrusion, whose length is subsequently reduced relative to the length of the optical waveguide travelling through the expander and is thereafter wound-up. The excessive length of the optical waveguide is consequently distributed uniformly along the overall length of the optical cable, because of the fact that the optical waveguides paid-out from the supply reel are stranded before they are fed into the extruder.

The invention relates to a roll manufactured with a light waveguide conductor (LWG-conductor), in particular for the transmission of optical signals from and to, respectively, a moving body. A perfect winding construction from which the conductor can be unreeled without interference is obtained in that the LWG-conductor (1) is wound to form a self-supporting cross-roll without a winding core.
