Abstract
A WDM (Wavelength Divisional Multiplex) device is provided in which a client signal having a band that is greater than a band of a wavelength used for wavelength-division multiplexing is allocated a plurality of wavelengths and is transmitted as a wavelength-division multiplexed signal. The WDM device includes a used-band detecting part for detecting a used-band that is used by the client signal supplied from a client device. The used-band is detected from a path layer of the client signal using set-up information contained in the path layer of the client signal. The WDM device also includes a mapping part for mapping the detected used-band onto wavelengths used for wavelength-division multiplexing.
