    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: PROBLEM TO BE SOLVED: To perform the control of an upstream network element without the monitor messaging of a software base by separately controlling a monitoring signal and a traffic signal to be transmitted from a downstream network element to the upstream network element. SOLUTION: The signal loss of an optical information carrier signal and the loss of the monitoring signal are detected from the input of a network element 120 as a result of a fiber disconnection 150 on an optical fiber path 130. Corresponding to the detection of the signal loss (traffic and monitor), an optical amplifier 122 is disconnected so that the traffic signal can not be transmitted from the optical amplifier 122 in the upstream network element 120 through an optical fiber path 131 to an optical amplifier 112 of a network element 110. Since the optical fiber path 131 is not actually disconnected, the monitoring signal to be supplied from a monitoring unit 125 to the optical amplifier 122 is supplied along with the optical fiber path 131 even when the optical information carrier signal does not exist, for example.

    Abstract: An arrangement is provided which detects the loss of a high power signal in an optical transmission path and the loss of supervisory signal power and, in response thereto, automatically invokes a procedure which causes an optical signal source connected to the fiber to reduce the power level at which it is transmitting optical signals over the fiber to a safe level. More specifically, reduction of optical signal power supplied by an upstream network element by a prescribed amount is achieved by automatically controlling the output power level of the upstream network element in response to the detection of both loss of signal power and loss of supervisory signal power at a downstream network element as a result of a fiber cut, open connector, or other potentially hazardous discontinuity.

    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.
