Original Abstract Submitted

A wavelength-tunable optical transmission unit is configured to be able to transmit a channel setting optical signal including first channel information indicating a channel of the first channel setting optical signal. When receiving a channel setting optical signal from another optical transceiver, a wavelength-tunable optical reception unit forwards second channel information indicating a channel of the channel setting optical signal. A control unit includes an arithmetic unit that sets the channel to be used for the transmission by the wavelength-tunable optical transmission unit and the channel to be used for the reception by the wavelength-tunable optical reception unit, and a non-volatile storage unit. The arithmetic unit writes, to the non-volatile storage unit, only information indicating the channel determined to be used for the transmission by the wavelength-tunable optical transmission unit and the channel determined to be used for the reception by the wavelength-tunable optical reception unit.
