Abstract

This paper presents an optical wavelength division multiplexed cross-connect topology, which is modified form of the existing optical cross-connect (OXC) topologies. An analytical approach is developed for the proposed topology to explore the effect of crosstalk induced in multichannel WDM networks due to OXC. Factors that affect the magnitude of crosstalk in the OXC are investigated and different parameters are optimized to reduce the total OXC-induced crosstalk. The crosstalk performance of the proposed topology is compared with the existing topologies. The scalability of the proposed topology in terms of wavelengths and input fibers as well as the total crosstalk in function of the number of cascaded OXC’s is presented. The bit error rate (BER) performance of a WDM optical system is evaluated at a bit rate of 10 Gb/s on account of OXC-induced crosstalk and different noises. The power penalty evaluated at BER = 10-9 shows that there is a significant impact of crosstalk on the number of wavelengths and input fibers. The results obtained from the present study demonstrate that the crosstalk performance of the proposed topology can be improved significantly than the existing topologies.Keywords: optical cross-connect, OXC-induced crosstalk, optical filter and switches, Wavelength division multiplexing.
