Abstract
We demonstrate near-error-free output-port contention resolution in a WDM switching node based on all-optical wavelength shifting. Contentio n between incoming 1-Gb/s data packets is resolved in real-time by com paring subcarrier-multiplexed control headers; on 2 input ports and th en all-optically wavelength-shifting one input signal to a free wavele ngth if contention occurs. Additionally, the 50-Mb/s subcarrier header itself is replaced and updated with new routing information.
