ABSTRACT:
An optical signal is transmitted via a transponder13, an all-optical node1, and a WDM device4including an optical filter38. A control means which includes a route and wavelength selecting functional part32, 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 filter38. A multi-rate functional part36sends 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 part37sends a wavelength varying request to set a wavelength of the optical signal according to the wavelength information. The optical filter38includes a bit rate (band) dependent wavelength multiplexing and demultiplexing functional part39.
