Optical cross-connects are one of the most important components in the dense wavelength division multiplexer based optical networks. The cross connects suffer from crosstalk due to the different wavelength light path channels during the switching process leading to the deterioration in Bit Error Rate (BER) and hence in the system performance. This paper presents the study of impact of coherent and incoherent crosstalk and power penalty on the optical cross-connects in WDM Networks. The effect of accumulation of coherent crosstalk at different stages of cross connect has been also investigated and analyzed for the blocking probabilities.
