摘要： An optical communication network node apparatus is provided that considerably reduces the node apparatus in scale, especially, a switch device in scale relative to increase in the number of wavelength multiplexes. With a routing operation on the basis of a wavelength at an intra-ring traffic step, light output from a plurality of demultiplexers is subjected to add/drop and routing processes and is directly or indirectly distributed to a plurality of multiplexers, and at an inter-ring traffic step (including a routing operation on the basis of a wavelength group), among lights output from a plurality of demultiplexers, light of another wavelength preliminarily set for inter-ring transmission and different from the light of the wavelength preliminarily set for the intra-ring transmission is subjected to the routing process, and, therefore, the node apparatus is considerably reduced to a smaller scale as compared to a node apparatus that achieves concatenation in a manner capable of routing lights of all the wavelengths to arbitrary optical rings.
