Abstract
A method for transmitting optical information between an emitter station and a receiving station via a multi-mode optical wave guide uses a wave length multiplex method. Several optical emitters generate a respective signal for each wave length to be transmitted. The signals are fed to the multi-mode optical wave guide in the form of a number of modes via mode multiplexers and wavelength multiplexers, the multi-mode optical wave guide having its own mode that can propagate within the multi-mode optical wave guide for each mode to be transmitted. After transmission and optionally regeneration and/or amplification of the signal via the multi-mode optical wave guide, the transmitted signals are broken down via the wavelength multiplexer into groups of signals having the same wavelength and via the mode demultiplexer into signals having the same mode. Subsequently, the interference signals are extracted from the transmitted demultiplexed signals.
