摘要
The cable (2) has an optical waveguide strand (6) and a core rod with steel wires (20) that run like a helix and lie together. Steel bands (22) are wound around the steel wires in opposite directions, where the steel wires and/or the steel bands have breadth lying in the range of 1 to 2 cms. The steel wires and/or the steel bands have two winding sections that are arranged at a distance to each other and next to each other in a longitudinal direction of the cable, where the distance of the winding sections corresponds to the breadth of the steel wires and/or the steel bands. An independent claim is also included for a rail comprising a signal cable guided parallel to a fiber optic cable.
