Claim 0:
1. An optical repeater device comprising:
an optical amplifier module including an amplifier optical circuit, the amplifier optical circuit including a plurality of amplification cores configured to amplify signal light propagating through different cores, and an optical amplifier control circuit configured to receive detection results from the amplifier optical circuit and generate a control signal directed to an excitation light source; and
a monitoring control circuit including a reception unit configured to receive monitoring control channel light, a transmission unit configured to transmit the monitoring control channel light, an information determination unit configured to determine whether monitoring control information transmitted by the monitoring control channel light received from the reception unit is for the optical repeater device or for another device, and a monitoring control unit configured to receive the monitoring control information from the another device via the reception unit and the information determination unit and transmit the monitoring control information of the optical repeater device to the another device via the transmission unit and the information determination unit,
wherein the monitoring control circuit collectively processes the monitoring control channel light for the respective different amplification cores.
