Abstract
In this paper we investigate the performance degradation in a wavelength division multiplexing network due to crosstalk in optical cross-connects. Worst-case analysis is carried out including in-band crosstalk components. In contrast with the approximate methods in the literature, all beat-noise terms are included, and both input signal hypotheses are considered. The results are obtained by using appropriate importance sampling strategies. The optimization of importance sampling parameters was done with new adaptive techniques based on stochastic Newton recursions, combined with a novel technique called the g-method. Accurate performance measures for practical system parameter values are obtained in short simulation run-times. Infinite and finite extinction ratios are considered. The results indicate that the detection threshold has a strong impact on the system performance. The importance sampling techniques are also useful for the optimization of this system parameter.
