ABSTRACT:
In an optical repeating system including an optical transmitter and optical amplifying repeaters, the optical transmitter specifies one optical amplifying repeater, and transmits to the optical amplifying repeater a supervisory command to supervise internal circuits of the optical amplifying repeater and a control command to control amplification factors of optical amplifiers of the optical amplifying repeater as a first sub-signal. Receiving the supervisory command via an optical transmission line, the optical amplifying repeater transmits a supervisory signal indicating a supervisory result corresponding to the supervisory command to optical receivers via optical transmission lines as a second sub-signal. Receiving the control command via the optical transmission line, the optical amplifying repeater is controlled to change amplification factors of the optical amplifiers in response to the control command.
