Abstract:
1. An optical repeating system comprising: multiple sets of optical transmission lines; an optical transmitter and an optical receiver for transmitting and receiving main signals via said multiple sets of optical transmission lines; and an optical amplifying repeater installed at an intermediate position on said multiple sets of optical transmission lines for amplifying and repeating the main signals with optical amplifiers, wherein said optical transmitter transmits a first sub-signal containing at least one of a supervisory command and a control command to said optical amplifying repeater, the supervisory command commanding to supervise internal circuits of said optical amplifying repeater, and the control command commanding to control said optical amplifying repeater, wherein said optical amplifying repeater includes a multiple sub-modules for amplifying and repeating the main signals on said multiple sets of optical transmission lines, and wherein each of said sub-modules transmits, when receiving the supervisory command via one of said optical transmission lines, a second sub-signal containing a supervisory signal indicating a supervisory result corresponding to the supervisory command to said optical receiver, and initializes, when receiving a predetermined control command via one of said optical transmission lines, another sub-module of said multiple sub-modules in response to the predetermined control command.
