Abstract
Provided is an optical relay system () which is capable of suppressing wasteful power consumption of an entire system to a low level. The optical relay system () includes a plurality of relay devices () and a network control device (). The network control device () causes an optical signal to be regenerated by a regenerative repeater () within the relay device () existing at an upstream of the relay device () reporting that the optical signal has deteriorated by a degree exceeding a predetermined level. Further, the network control device () causes the regenerative repeater () to stop regenerating the signal in a case where deterioration of the signal remains within an allowable range even when the regenerative repeater () stops regenerating the signal.
