An optical communication system includes a plurality of optical channels, each of which passes a single optical wavelength signal. Each of the plurality of optical channels includes an optical amplifier which is controlled to operate at a predetermined output power level independent of channel wavelength and input power level by operating each optical amplifier in a saturation mode. Pumping power for operating each optical amplifier in the saturation mode is supplied from shared optical pumps or a plurality of one per channel optical pumps.

L'invention porte sur un système de télécommunications à plusieurs canaux optiques transmettant chacun un seul signal de longueur d'onde optique. Chacun desdits canaux comporte un amplificateur conçu pour fournir une puissance de sortie prédéterminée indépendante de la longueur d'onde des canaux et de la puissance du signal d'entrée, et fonctionnant en mode saturation. La puissance de pompage nécessaire au fonctionnement des différents amplificateurs optiques en mode saturation est fournie soit par des pompes optiques communes, soit par des pompes individuelles (une par canal).
