Abstract

The statistical impact of Coherent and Incoherent crosstalk contributions in a proposed Grouped Share-Per-Wavelength and an Ungrouped Share-Per-Node L-WIXC configuration due to different group size, optical propagation delay differences, bit duration etc. is compared both theoretically and analytically. Considering coherent and incoherent crosstalk analytical expressions of electric field, leakage crosstalk, Bit-Error-Rate (BER) and power penalty (pp) are developed in both cases. Besides, the effect of grouping scheme and all crosstalk contributions on the performance of L-WIXCs are numerically calculated and the results obtained, are thoroughly compared on the basis of optimum number of wavelength converters, number of inputs channels and number of wavelengths per input channel.
