Paper Abstract

Crosstalk induced interferometric noise has been found to constrain the performance of optical switching networks. A computer design and simulation package has been used to analyze the effect of this noise on optical TDM crossconnects. This software tool is able to calculate all possible routes that a signal may traverse within a crossconnect for a given input/output assignment, and also incorporates a theoretical analysis of interferometric noise. It has been found that for a crossconnect capable of switching 512 independent channels, the constituent 2 x 2 crosspoints must possess isolations better than -20 dB, and the switch architecture must be dilated.
