Cascading of a non-blocking WDM cross-connect based on all-optical wavelength converters for routing and wavelength slot interchanging

The authors demonstrate experimentally the possibility of cascading five optical cross-connects based on all-optical wavelength converters used for routing and wavelength slot interchanging at a channel rate of 10 Gbit/s. Furthermore, the possibility of both up- and down-conversion from external to internal wavelengths is demonstrated, as well as an input power dynamic range of 12 dB.
