Optical cable and method for production of an optical cable
First Claim
1. An optical cable, comprising:
- a cable core with a plurality of optical transmission elements, each optical transmission element including at least one optic fiber;
a first sleeve made from a material containing paper, the first sleeve surrounding the plurality of optical transmission elements;
at least one yarn arranged in a region of the cable core between the first sleeve and the plurality of optical transmission elements, the at least one yarn comprising a swellable material; and
a cable jacket surrounding the first sleeve and containing a plastics material.

Abstract
An optical cable comprises a swelling yarn, around which several optical transmission elements in the form of micromodules are arranged. A micromodule comprises a bundle of optic fibers, which are surrounded by a sleeve made from a material of plastic. Further swelling yarns are arranged around the optical transmission elements. The optical transmission elements and the swelling yarns are surrounded by a sleeve of paper. The paper sleeve is surrounded by a cable jacket made from a material of plastic. When an optic fiber is exposed, the cable jacket is pulled off, whereupon the paper sleeve tears off and can consequently be easily removed.
