Abstract
A signal transmission system that includes a plurality of transceivers that transmits and receives an optical signal, a gateway that receives the optical signal transmitted by the transceiver, performs optical-electrical conversion and electrical-optical conversion for the received optical signal, and outputs the converted optical signal, an optical switch, a transceiver control unit that controls an operation of the transceiver, and a management unit that determines the wavelength of the optical signal transmitted by the transceiver, in which the management unit determines the wavelength of the optical signal to be transmitted by a transmission-scheduled transceiver that is the transceiver scheduled to transmit the optical signal according to a predetermined rule in a case of acquiring transmission schedule notification information indicating the transmission-scheduled transceiver, and after the determination of the wavelength, the transceiver control unit causes the transmission-scheduled transceiver to transmit the optical signal of the determined wavelength.
