摘要

A light wave guide, especially for a vehicle, comprises an optical fibre (1) made of a polymer, and a protective layer which surrounds it. The protective layer consists of a metal pipe (2) with corrugations at an angle to its longitudinal axis. The pipe acts as an electrical conductor and has an external insulation.
