Optical cable with at least one optical waveguide

An optical cable, comprising:

• at least one optical waveguide a protective covering over said at least one optical waveguide and a substantially rectangular internal opening in said protective covering which forms a chamber for accepting optical fibers, a number of ribbon conductors each having a plurality of optical fibers, said ribbon conductors being accommodated in the chamber arranged as a ribbon conductor stack, and the optical waveguide having a bending plane with a smallest bending resistance and the ribbon conductors being arranged with their broad sides substantially parallel to said bending plane, the ribbon conductor stack being guided in an undulatingly curved fashion in the chamber such that an excursion of the ribbon conductor stack extends transverse to the bending plane with the smallest bending resistance, the chamber being of a height of such dimension that an upper limit of mechanical loading on the ribbon conductors is not exceeded by tension on an outermost ribbon conductor of the ribbon conductor stack and by compression of an innermost ribbon conductor of said ribbon stack when said optical cable is wrapped on a smallest foreseeable radius drum, owing to undulating guidance of the ribbon conductor stack the ribbon conductor stack forms a type of strip spring structure, and the ribbon conductors have lateral play with respect to a chamber wall such that turning up or down or cross-positioning of the ribbon conductors in said chamber is prevented.
