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 

Alternate common port 

Flexgrid Dynamic Channel Width Control(fully ITU flexible grid G.694.1 compliant) 

          6.25GHz Width Resolution(default,3.125GHz)

          No constraints on the spectrum allocated to a super-channel 

          Hitless channel widening,narrowing and migration with 6.25 GHz resolution 

          Flexgrid Dynamic Attenuation Control 

          6.25 GHz Resolution 

          0-15dB Range 

          Hitless channel and intra-channel power equalization

          LCoS Switching Technology 

          Frequency range:6THz(dault)-wider frequency range up to 12THz (C+L) can be supported ØTrueFlex grid-less operation              to 6.25GHz granularity or less 

          Intra-channel “slice”attenuation control 

          Future-ready support for coherent 40G,100G,super channels and beyond 

          Very high spectral resolution for node cascadability 

          Low profile (20 mm) package available for single-slot blade design 


      Applications

          ROADM all-optic Network
