摘要: A transmitting apparatus has a plurality of optical signal transmitters, transponders for converting the wavelengths signals transmitted from transmitters into respective and wavelength-converted signals, wavelength-division-multiplexer wavelength-division-multiplexing an auxiliary transponder wavelength different signal. The are monitored by supervising unit, which outputs detected failure when it detects one transponders. In response to signal, transmission switch supplies output transponder, rather than failing wavelength-division-multiplexer. control unit transmits path. receiving switches corresponding transponder.
