Abstract
An optical signal is transmitted via a transponder, an all-optical node, and a WDM deviceincluding an optical filter. A control means which includes a route and wavelength selecting functional part, 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. A multi-rate functional partsends 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 partsends a wavelength varying request to set a wavelength of the optical signal according to the wavelength information. The optical filterincludes a bit rate (band) dependent wavelength multiplexing and demultiplexing functional part
