Abstract
Provided is a node device in an optical communication system in which a plurality of node devices are connected by a plurality of optical fibers, including: at least a first optical transceiver that consumes a first power consumption amount during standby; at least a second optical transceiver that consumes a second power consumption amount greater than the first power consumption amount during standby; and a power consumption control unit that preferentially selects the second optical transceiver as an optical transceiver to be maintained by the node device, the second optical transceiver being in a fast startup standby mode in which startup time from a standby state is shorter than allowable time of interruption time of a communication service in the optical communication system.
