Abstract:
1. A method for controlling an optical amplifier configured to receive a gain control signal from a controller, the method comprising: determining an anticipated number of optical channels within a multiplexed optical signal to be amplified by said optical amplifier; selecting an initial level of amplification as a function of said anticipated number of optical channels within the multiplexed optical signal and a desired power level of the resulting amplified multiplexed optical signal; amplifying the multiplexed optical signal according to the initial level of amplification; modifying the level of amplification including modification of individual power levels of optical channels in response to a change in the number of optical channels within the multiplexed optical signal according to a predefined algorithm; and limiting the level of amplification in response to a detected power level of the resulting multiplexed optical signal being greater than a desired power level due to a positive transient.
