The present invention is directed to a communication cable with a cable core provided in the center surrounded by an outside cladding as well as strain relief elements applied in the region of the outside cladding.
Allowed U.S. patent application Ser. No. 08/646,322 which issued as U.S. Pat. No. 5,706,381, whose disclosure is incorporated by reference and which is a national phase application based on WO-A1 95/13556, discloses a cable having strain relief elements adjacent the outside surface of the cable. The tensile elements are arranged in the cladding region and lie in a symmetrical plane that simultaneously forms the bending plane for the cable. The tensile elements lie diametrically opposite one another and thus are offset by 1800 from one another. The light waveguides are arranged in the center of the cable in a single layer or in a multi-layer envelope.
In many instances, it is desirable to construct cables in a type of hybrid structure, for example to arrange a plurality of transmission elements that are at least partially independent of one another in the cable. For example, this is the case where both electrical as well as optical transmission elements are employed. However, applications with two or more optical transmission elements are also conceivable in this context.
