Optical cross – connect routing node demonstrator for DWDM wavelength path networks

We describe the design and performances of a strictly non-blocking optical cross-connect node demonstrator for WDM wavelength path networks. The optical cross-connect (OXC) prototype was experimentally tested as an 2 x 2 WDM system with two input / output ports and two wavelengths per port. The OXC was inserted in a 95 km network with a STM-16 bit stream per channel. The performance of a single and a cascade of OXC’s were simulated and the results verified against the experimental ones.
