CA 2607122

An optical amplifier including an input port and an output port which are coupled together via a data signal line; an amplifier circuit; a gain control circuit coupled to the data signal line and operative for detecting the power level of a burst signal input into the optical amplifier at the input port; and a dummy laser generation circuit having an output coupled to the data signal line and an input coupled to the gain control circuit; where the gain control circuit is operative for controlling the power level output by the dummy laser generation circuit so as to maintain the power level of a signal input into the amplifier circuit at a substantially constant level.
