ABSTRACT:
In an optical communication system in which a plurality of optical nodes are connected via an optical transmission path and communication is performed by multiplexing a plurality of channels in the optical transmission path, transmission is performed by a transmitting optical node using a wavelength belonging to a wavelength group constituting a single channel. Each of the plurality of channels is constituted by a wavelength group consisting of a plurality of wavelengths separated from each other by a predetermined first wavelength interval. Reception is performed by a receiving optical node which detects a light transmitted in the optical transmission path and which has a plurality of light detectivity peaks separated by intervals corresponding to a natural number multiple of the predetermined first wavelength interval so that the light detectivity peaks match with the wavelengths constituting the wavelength group of a required channel.
