Abstract
Provided is an optical apparatus including: wavelength separation units corresponding to the respective routes, each of which divides a wavelength multiplexed optical signal of one route into M wavelength groups (M is an integer satisfying N×M=the number of multiplexed wavelengths of the wavelength multiplexed optical signal of one route), each of which includes N wavelengths (N is an integer of 2 or more); and M wavelength separation blocks, each of which is input with a plurality of the wavelength groups divided by the different wavelength separation units and outputs optical signals with any one or a plurality of wavelengths included in the input wavelength groups to N coherent transponders. Accordingly, it is possible to flexibly adapt to extension in wavelength or extension in route in units of a wavelength separation block and/or wavelength multiplexing block.
