In an optical fibre (1), a coupling face (4) is constructed in such a manner that only light coming from one direction can be coupled out and light can only be coupled in in one direction. As a result, the power losses are very low. In a motor vehicle, various electric or electronic assemblies having such directional couplers are coupled to an optical fibre constructed as ring line and connected to the two interfaces of a head processor. <IMAGE> |
