Abstract
An optical transmission apparatus includes a splitter configured to split a first wavelength division multiplexed optical signal arranged in a first wavelength band and a second wavelength division multiplexed optical signal arranged in a second wavelength band, respectively, from an optical signal including the first wavelength division multiplexed optical signal and the second wavelength division multiplexed optical signal, a wavelength converter configured to convert a wavelength of the split second wavelength division multiplexed optical signal to generate a third wavelength division multiplexed optical signal to be arranged in the first wavelength band, an optical monitor configured to monitor power of each wavelength channel of the third wavelength division multiplexed optical signal, and a transmitter configured to transmit a monitoring result by the optical monitor to a transmission source node of the optical signal or a relay node of the optical signal.
