摘要
A multi-failure resolution optical node includes an operating system wavelength path and two or more standby system wavelength paths which are assigned to the operating system wavelength path and have been assigned a ranking. It further includes a node control unit that can separately operate the operating system wavelength path and the standby system wavelength paths in a normal power consumption mode or a reduced power consumption mode. Thus, it is possible to provide an optical node with which power consumption is reduced and with which switching to a standby system wavelength path can be performed quickly in response to a failure in the operating system wavelength path.
