Sunesys recently announced a new network product, the “SunTran Data Center Transport Network.” The heart of which is the ROADM, or Reconfigurable Optical Add-Drop Multiplexer. ROADM is an all-optical switching element allowing for the user to remotely add and or drop wavelengths to/from a DWDM stream without having to terminate the traffic.
This is achieved through the use of a Wavelength Selective Switching (WSS) module which allows individual or multiple wavelengths carrying data channels to be added and/or dropped from a transport fiber without the need to convert the signals on all of the WDM channels to electronic signals and back again to optical signals as in an Optical Electrical Optical (OEO) module.
