The dynamic gain control system includes a pump source providing pump light. The dynamic gain control system measures a certain portion of the input pump light into the optical amplifier and measures a certain portion of the output pump light from the optical amplifier. The dynamic gain control determines the pump light loss based on the input pump light and output pump light measurements. Based on the pump light loss, the dynamic gain control system maintains the pump light loss relatively constant (for example 0.1 dB) independent of the number of input channels and their relative powers (for example, input channel powers of-50 dBm to 10 dBm) by providing feedback to control the output pump light. In doing so, the dynamic gain control system maintains the inversion level of the optical amplifier. A relatively constant inversion level corresponds to only small variations in the gains of the input channels (multi-channel gain) as a result of changes in the input channels to the optical amplifier.

Système de commande de gain dynamique comprenant une source de pompage fournissant une lumière de pompage. Le système de commande de gain dynamique mesure une certaine partie de la lumière de pompage d'entrée dans l'amplificateur optique et mesure une certaine partie de la lumière de pompage de sortie de l'amplificateur optique. La commande de gain dynamique détermine la perte de lumière de pompage compte tenu des mesures de la lumière de pompage d'entrée et de la lumière de pompage de sortie. D'après la perte de lumière de pompage, le système de commande de gain dynamique maintient la perte de lumière de pompage relativement constante (p. ex., 0,1 dB) peu importe le nombre de canaux d'entrée et leurs puissances relatives (p. ex., des puissances au canal d'entrée de 50 dBm à 10 dBm) en offrant une rétroaction pour régler la lumière de pompage de sortie. Ce faisant, le système de commande de gain dynamique maintient le niveau d'inversion de l'amplificateur optique. Un niveau d'inversion relativement constant ne correspond qu'à de petites variations dans les gains des canaux d'entrée (gains multicanaux) par suite des changements dans les canaux d'entrée de l'amplificateur optique.
