Abstract

Selon l"invention, une liaison optique sans perte dans un système de transmission optique comprend une fibre optique configurée pour produire un gain de Raman et fournir un gain de Raman réparti, par l"intermédiaire d"une ou de plusieurs sources de pompage, le long de la fibre afin que, au bout du compte, le gain réalisé par un ou plusieurs signaux de propagation dans la liaison optique soit suffisamment uniformisé le long de la liaison optique ou au moins sur une partie de ladite liaison, pour ne pas subir un écart, par exemple, supérieur à cinq dB sur la longueur de la fibre optique. Les différentes formes de réalisation décrites mettent en oeuvre différentes architectures de pompage/élément optique permettant d"atteindre le résultat escompté.
