This paper has presented different wavelength division multiplexing techniques that have dramatically increased the capacity of optical transmission systems. Its main advantages have made it the current favorite multiplexing technology for optical networks. That is no doubt that Crosstalk is generated when a demultiplexer separates incoming wavelengths onto different output fibers. Optical cross connect (OXC) is a device which is used for switching high speed optical signals. We have deeply investigated the performance analysis to find the dramatic effect of crosstalk in different multiplexed optical networks. Firstly, the performance in coarse wavelength division multiplexing (CWDM) have been investigated and then compared the results with using two multiplexing techniques namely, wavelength division multiplexing (WDM) and dense wavelength division multiplexing (DWDM). Signal to noise ratio (Q) or signal quality factor, bit error rate (BER), and power penalty are the major interesting performance parameters in the current study. System parameters optimization are applied to reduce the effect of crosstalk.
