Demonstration of a robust WDM cross-connect cascade based on all-optical wavelength converters for routing and wavelength slot interchange

Cascading of up to 10 multiwavelength optical cross-connects based on all-optical wavelength converters for wavelength-slot-interchanging and routing is demonstrated experimentally at a channel rate of 10 Gbit/s. An input power dynamic range of more than 15 dB is shown.
