摘要： An optical repeating system includes an optical transmitter and a plurality of optical amplifying repeaters. The optical transmitter specifies a part or all of the optical amplifying repeaters, and transmits a supervisory command to the specified optical amplifying repeaters as a first sub-signal via an uplink or downlink optical transmission line. The supervisory command is a command to supervise internal circuits of the optical amplifying repeaters. Receiving the supervisory command addressed thereto via the uplink or downlink optical transmission line, the optical amplifying repeaters each transmit a supervisory signal indicating a supervisory result corresponding to the supervisory command to optical receivers via the uplink and downlink optical transmission lines as a second sub-signal. The optical system can reduce the time take to acquire the supervisory information about the plurality of the optical amplifying repeaters.

摘要： An optical repeating system includes an optical transmitter and an optical amplifying repeater. The optical transmitter transmits a supervisory command and a control command to the optical amplifying repeater as a first sub-signal. The supervisory command is a command to supervise internal circuits of the optical amplifying repeater, and the control command is a command to control the optical amplifying repeater. The optical amplifying repeater includes multiple sub-modules each for amplifying and repeating main signals on multiple sets of optical transmission lines. When receiving the supervisory command via the optical transmission line, each sub-module transmits a supervisory signal indicating the supervisory result associated with the supervisory command to an optical receiver as a second sub-signal. In addition, when receiving a predetermined control command via the optical transmission line, each sub-module initializes another sub-module of the multiple sub-modules in response to the predetermined control command. The optical amplifying repeater can restart its control program even when it has fallen into a state where it is difficult to continue to execute the normal operation in accordance with the control program because of some exception or the like.

摘要： 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.

摘要： A supervisory system and supervisory method of an optical amplifier repeater are proposed that can implement operation supervision taking account of the characteristics of individual supervisory targets of the optical amplifier repeater, thereby achieving higher reliability. The supervisory system includes an optical transmitter for transmitting an optical signal including an operation command to notify of a state of a supervisory target; an optical amplifier repeater that transmits a response optical signal including a response code obtained by measuring the supervisory target in response to the operation command; an optical receiver for receiving the response optical signal via an optical fiber and an information processing unit for converting the response code into a numerical form by using a predetermined expression that links the response code with measured information obtained by measuring in advance the supervisory target with an external measuring device during operation of the optical amplifier repeater in response to the operation command.
