Abstract
For a WDM device including a multiplexer receiving fixed wavelengths, wavelength-converting parts for converting input wavelengths from optical transmission devices into the fixed wavelengths, and interface parts provided between the multiplexer and the wavelength-converting parts and having a specific wavelength that matches the fixed wavelength of the multiplexing part, a method and a device is provided for automatically determining the specific wavelength of the interface part that is to be selected as a converted wavelength output from the wavelength-converting part.
