A method of, and system for, controlling the level of one or more wavelength channels added to an optical fibre trunk (10) of a WDM system from a branch terminal via a saturated amplifier (28) in which an additional wavelength signal differed from the wavelength of wanted channels is introduced to the input of the saturated amplifier (28) to reduce the level of the added wanted channel(s).

Procédé et système associé de régulation du niveau d'une ou plusieurs voies de longueur d'onde ajoutées à un réseau (10) de fibres optiques d'un système de multiplexage optique à partir d'un terminal ramifié au moyen d'un amplificateur saturé (28) dans lequel un signal de longueur d'onde additionnel différé de la longueur d'onde des voies voulues est envoyé à l'entrée de l'amplificateur saturé (28) pour réduire le niveau de la voie ou des voies voulues ajoutées.
