Title (EN) OPTICAL AMPLIFIER DEVICE
(FR) DISPOSITIF D'AMPLIFICATEUR OPTIQUE
Abstract: front page image
(EN)An optical amplifier device comprising an optical amplifier (3) for amplifying an input signal light, output sensing means (5) for measuring the output level of the optical amplifier, output control means (6) for controlling the output level of the optical amplifier in accordance with the output level measured by the output sensing means (5), gain gradient sensing means (7) for measuring the gain gradient relating to the wavelength of the optical amplifier, and gain gradient control means (8) for controlling the gain gradient of the optical amplifier (3) in accordance with the gain gradient measured by the gain gradient sensing means (7).
(FR)Un dispositif d'amplificateur optique comprend un amplificateur optique (3) qui amplifie une lumière de signal de sortie, un moyen (5) de détection de la sortie qui mesure le niveau de sortie de l'amplificateur optique, un moyen (6) de commande de la sortie qui commande le niveau de sortie de l'amplificateur optique en fonction du niveau de sortie mesuré par le moyen (5) de détection de la sortie, un moyen (7) de détection du gradient de gain se rapportant à la longueur d'onde de l'amplificateur optique et un moyen (8) de commande du gradient de gain qui commande le gradient de gain de l'amplificateur optique (3) en fonction du gradient de gain mesuré par le moyen (7) de détection du gradient de gain.
