Title:
WAVELENGTH CROSS-CONNECT DEVICE AND WAVELENGTH CROSS-CONNECT METHOD
Document Type and Number:
WIPO Patent Application WO/2023/199397
Kind Code:
A1
Abstract:
A wavelength conversion unit (20) of a WXC device (100) comprises: input-side WSSes (21) which respectively output optical signals input from input ports of the WXC device (100) to any of a plurality of converters (23); and the converters (23) which respectively convert wavelength bands of optical signals input from the input-side WSSes (21), which handle the optical signals input from the respective input ports, into other wavelength bands, and output the converted optical signals to output-side WSSes (24), wherein a controller (30) manages whether the states of the converters (23) are in usage states or unused states, and controls the input-side WSSes (21) to output the output signals to the converters (23) in the unused states.
