The statistical impact of Coherent and Incoherent crosstalk contributions in a proposed single stage and a multi-stage L-WIXC configuration due to different 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 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 and number of wavelengths per input.
