Abstract
Each of a series of optical amplifiers is arranged such that, in response to detecting particular stimuli occurring at an input or receipt of an adjustment start message from an upstream amplifier, adjusts certain amplifier parameters using small steps and completes the adjustment using large steps if it does not receive the adjustment start message within a predetermined period of time of starting the adjustment in response to detecting the stimuli. If the optical amplifier receives the adjustment start message, then it continues to perform the adjustment and completes the adjustment using large steps when it receives an adjustment done message from the upstream optical amplifier. At that point, the optical amplifier sends an adjustment done message to the next downstream amplifier if it is not the tail-end amplifier.
