Abstract: PROBLEM TO BE SOLVED: To improve the reaction of conventional optical amplifiers on the downstream in an optical transmission system, having the optical amplifiers placed along an optical transmission path, when the optical amplifiers encounters a change in the intensity level of an input optical signal. SOLUTION: Each of a series of the optical amplifiers is adjusted, so as to regulate a specific amplifier parameter at a small step in reaction to the detection of a specific stimulus, caused by an input or the reception of a regulation start message from an upstream amplifier and to complete the regulation at a large step when no regulation start message is received within a prescribed time elapse from the start of the regulation reacting to the detection of the stimulus. Receiving the regulation start message, each optical amplifier continues the regulation, and completes the regulation at a large step, when a regulation end message has been received from the up-stream optical amplifier. Each optical amplifier transmits regulation end message to the next, downstream amplifier, if the optical amplifier is not the end amplifier at thst time.

Abstract: A method, apparatus and system for controlling power transients in amplified optical transmission system includes, in response to the detection of a power transient in an optical signal, varying a gain of at least one amplifier to correct for a time delay in a gain response associated with a gain change in an amplifier. Alternatively, the method, apparatus and system further include in response to the detection of the power transient, adjusting the gain of at least one amplifier to correct for a change in signal power.
