The Mini 50 WSS (wavelength selective switch) announced by JDSU is a next-generation 50-GHz module that supports network traffic through more than 16 nodes, or entry and exit points in a network, with minimal effect on the network signal. The reconfigurable optical add/drop multiplexer is an N-port module that comprises a hermetically sealed optics block with control electronics. The switch dynamically attenuates, block switches and routes wavelengths independently. Any wavelength(s) can be routed from any port(s) to any other port(s) in any order. It is Telcordia-qualified and RoHS-compliant and operates in open- and closed-loop-control modes.
