Paper Abstract

We demonstrate near-error-free output-port contention resolution in a WDM switching node based on all-optical wavelength shifting. Contention between incoming 1-Gbit/s data packets is resolved in real-time by comparing subcarrier-multiplexed control headers on 2 input ports and then all-optically wavelength-shifting one input signal to a free wavelength if contention occurs. Additionally, the 50 Mbit/s subcarrier header itself is replaced and updated with new routing information.
