Simulative investigations of power penalty for DWDM link in the presence of FWM

In this paper, the eight channels dense wavelength division multiplexing (DWDM) optical communication system has been simulated, and power penalty introduced due to neighboring channels required to compensate the crosstalk has been calculated. It has been observed that the intermediate channels are more affected as compared to the boundary channels and more power is required to compensate the loss of information due to crosstalk.
