Paper Abstract

Crosstalk is a major concern in optical switching networks made of 2 X 2 electro-optical switches such as Dilated Benes Networks (DBNs). One of the important performance parameters of these optical architectures is SXR (Signal-to-Crosstalk Ratio). The paper proposes ways to automate the process of obtaining crosstalk ratios and their related characteristics. This paper contains two parts. The first part is an algorithm to obtain the crosstalk ratios of each and every switch in a DBN. These results can be used to calculate the SXR of the network or to detect and locate switches with excessive crosstalk. In the second part, we present a feasible way to configure a network to obtain an approximate value of its worst-case SXR. The difference between the actual and the approximate worst-case SXR values is almost negligible, while the complexity involved in obtaining the actual worst-case SXR can be prohibitively high.
