Abstract
An amplifying module for an optical network has a fiber amplifier for amplifying a multiplexed optical stream having a plurality of wavelength channels. The fiber amplifier has a set point gain. The module has module control means for controlling the operating conditions of the fiber amplifier and supplying means for supplying to the module control means information representative of the channel loading condition. In response to the information, the module control means adjusts the operating conditions of the fiber amplifier such that the fiber amplifier gain does not exceed an acceptable deviation limit away from a set point gain.
