Performance Degradations due to Crosstalk in Multiwavelength Optical Networks U...
P. S. André; J. L. Pinto; A. Nolasco Pinto; T. AlmeidaThe impact of homodyne and heterodyne crosstalk on an optical signal passing through an optical add drop multiplexer (OADM) node in dense wavelength division multiplexing (DWDM) network is studied, and the analytical expressions for the power penalty are obtain. The statistical impact of crosstalk on signal is studied by simulation and the results compared with experimental data. ;...

André, P. S.; Pinto, J. L.; Teixeira, A. J.; Pinto, A. Nolasco; Almeida, T.; Morgado, F.; Pousa, M.In this paper, we assess the design and performances of a strictly non-blocking all-optical cross-connect demonstrator node for WDM wavelength path networks. The all-optical cross-connect (AOXC) prototype was experimentally tested in a small 2 x 2 WDM network with a STM-16 bit stream per channel. The single and cascaded performance of the AOXC was also simulated and its results were validated with the experimen...
