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.
