Abstract

The statistical impact of Coherent and Incoherent Crosstalk Contributions on the performance of a proposed single stage and a multi-stage Share-per- Node L − WIXC configuration and a multi-stage Share-per-Wavelength L − WIXC configuration in terms of different Optical Propagation Delay Differences, Bit Duration etc., is compared both theoretically and analytically. Besides, considering Coherent and Incoherent Crosstalk contributions for each of those cases, analytical expressions of Electric Field, Leakage Crosstalk, Bit-Error-Rate (BER) and Power Penalty (pp) are being developed. Finally, the results obtained numerically, are thoroughly compared on the basis of Optimum Number of Wavelength Converters, Number of Inputs and Number of Wavelengths per Input Channel.
