Abstract
A wavelength cross connect device includes: a WXC unit including input-side WSSes and Output-side WSSes; and a wavelength band switching unit. Of wavelength multiplexed signal beams N-split by each input-side WSS, wavelength multiplexed signal beams in which optical signals for which wavelength band conversion is not necessary are multiplexed are input to the output-side WSSes. The wavelength band switching unit performs wavelength band conversion on, of the N-split wavelength multiplexed signal beams, a selected wavelength multiplexed signal beam in which optical signals for which wavelength band conversion is necessary are multiplexed, to generate a wavelength-band-converted wavelength multiplexed signal beam in which the wavelength bands of optical signals of distinct wavelength bands multiplexed in the wavelength multiplexed signal beam have been converted, and outputs the wavelength-band-converted wavelength multiplexed signal beam to one of the output-side WSSes so as to be rerouted.
