description A method and apparatus is provided for automatically controlling the gain of an optical amplifier. The method begins by generating a first control signal based on a feed-forward error signal and a second control signal based on the feedback error signal. Next, the pump source is adjusted in accordance with the control signals. In this way both the speed of a feed-forward arrangement and the accuracy of a feedback arrangement can be achieved.
