An improved optical cable having at least one light waveguide having a coating and other component parts in the form of protective sheaths of plastic material as well as potentially tensile elements and filling compounds. The improved cable being recyclable, since the other component parts contain only polyolefins and small amounts of glass or inorganic fillers, so that the cable can easily be recycled into pellets having the inorganic fillers and glass acting as reinforcing elements.

Method for the re-utilization of an optical

An elongated optical transmission element has a plurality of light waveguides which are continuously mechanically connected to one another in various planes to form a structure extending in a longitudinal direction so that the cohesion between waveguides is essentially obtained by connections on the inside of the structure. The structure can be used in an optical and/or electrical lead and is used in optical and/or electrical cables.

Elongated optical transmission element

The present invention relates to polyalkylene terephthalate/polycarbonate blends stabilized with carbodiimides as a sheathing material for optical fibres.

Sheathing material for optical fibers, based on polyalkylene

An optical cable comprises a plurality of light waveguides which are arranged at least one group with a prescribed structure. The light waveguides will have different mechanical sensitivities, with the waveguides having a low mechanical sensitivity being in those regions of the structure which have elevated mechanical stressing occurring.
