Abstract

An optical cable having at least one optical light waveguide arranged in a protective covering or shell and including at least one support element characterized by each of the support elements consisting of stranded threads impregnated with a hardening resin and covered with a protective layer and the support elements being stranded onto the protective covering or shell of the light waveguide. The method of manufacturing the cable includes providing each of the support elements by providing a plurality of threads, stranding said threads together into a group and impregnating with resin each of the groups of strands of the stranded threads, subsequently covering each of the impregnated groups with the protective layer which permits a subsequent hardening of the resin, to form the element and then subsequently providing a light waveguide received in a protective covering and stranding the support elements onto the protective covering of the waveguide to form the cable.
