Abstract
An optical signal is transmitted via a transponder 13, an all-optical node 1, and a WDM device 4 including an optical filter 38. A control means which includes a route and wavelength selecting functional part 32, transmits a request band information and a wavelength information based on a requested band information, link information of a network, and band limitation information with respect to each filter wavelength of the optical filter 38. A multi-rate functional part 36 sends a bit rate varying request to set a band to be requested to the network side according to the requested band information. A wavelength varying functional part 37 sends a wavelength varying request to set a wavelength of the optical signal according to the wavelength information. The optical filter 38 includes a bit rate (band) dependent wavelength multiplexing and demultiplexing functional part 39.
