Wavelength Selective Switch (WSS)
Wavelength selective switch(WSS) is one of the core optical devices of the next-generation Reconfigurable Optical Add-Drop Multiplexer(ROADM) and optical cross-connect(OXC) in all-optical networks.It has Colorless, Directionless, Contentionless, Flexible Grid(CDC-F) and other all-optical signal processing functions,and can support any port wavelength and arbitrary uplink and downlink functions.
Features
