| 摘要 |
The invention relates to a method for transmitting optical information between an emitter station (7) and a receiving station (6) via a multi-mode optical wave guide (3) using a wave length multiplex method. According to the invention, several optical emitters (OS) generate a respective signal (TX) for each of the wave lengths to be transmitted, and the signals (TX) are fed to the multi-mode optical wave guide (3) in the form of a number of modes via mode multiplexers (MM) and wavelength multiplexers (WM), the multi-mode optical wave guide (3) having its own mode that can propagate within the multi-mode optical wave guide (3) for each of the modes to be transmitted and after the transmission and optionally the regeneration and/or amplification of the signal via the multi-mode optical wave guide (3), the transmitted signals are broken down via the wavelength multiplexer (WD) into groups of signals having the same wavelength and via the mode demultiplexer (MD) into signals having the same mode, and subsequently, the interference signals are extracted from the transmitted demultiplexed signals (RX), the interference signals being formed due to over coupling between the individual modes during the transmission via the multi-mode optical wave guide (3).
