Abstract :
A red-shift optical filter all-optical wavelength converter compatible to all-optical WDM networks is introduced and demonstrated at 40 and 10 Gb/s. The wavelength converter provides reshaping and can act as a power equalizer. We use the device to overcome wavelength blocking in a looped-fiber network demonstration equivalent to 42 cross-connect switches and a 16800 km transmission distance.
