Abstract
A wavelength-multiplexing optical transmission apparatus includes an optical-wavelength-information storing unit that stores optical wavelength information on an optical wavelength of an optical signal to be output from a transponder, and an optical-wavelength-information transmitting unit that transmits the stored optical wavelength information to the transponder via a connection cable. The transponder includes an optical-wavelength control unit that controls an optical wavelength of an optical signal to be input to a wavelength multiplexing unit based on the optical wavelength information received from the optical-wavelength-information transmitting unit.
