Abstract
Provided by the invention is a fast, continuously variable AGC that can be used to control the gain of an optical amplifier. The AGC is designed around a controller having control coefficients that may be dynamically adjusted according to operating conditions. According to an embodiment of the invention provided is an AGC that can operate at much higher speeds in comparison with prior art AGC designs that have fixed control coefficients, while simultaneously maintaining stability over all operating conditions.
