An optical transmission system comprising a first optical waveguide suitable for transmitting a first information signal, a second optical waveguide suitable for transmitting a second information signal, and input means for providing an electro magnetic radiation signal into said first waveguide, said signal being suitable for providing Raman amplification of the information signals, the system further comprising an optical coupling between said waveguides, arranged to transmit at least a portion of the Raman amplification signal from the first waveguide to the second whilst substantially blocking the transmission of the information signals between the waveguides.
L'invention concerne un système de transmission optique comprenant un premier guide d'onde conçu pour émettre un premier signal d'information, un second guide d'onde conçu pour émettre un second signal d'information, et un moyen d'entrée permettant de produire un signal de rayonnement électromagnétique dans le premier guide d'onde, ledit signal étant destiné à produire une amplification Raman des signaux d'information. Ledit système consiste en outre en un couplage optique entre les guides d'onde, agencé de manière à émettre au moins une partie du signal d'amplification Raman à partir du premier guide d'onde vers le second tout en bloquant la transmission des signaux d'information entre les guides d'onde.
