Effect of SRS-XPM-FWM-ASE Nonlinearity in Optical Communication System

Yogita Thareja , Gurmeet Singh

In all-optical communication system, the signal remains in optical domain between the transmitter and receiver. As the optical signal propagates from the transmitter towards receiver, due to physical layer impairments of the network, its quality degrades. The factors affecting the physical layer of the optical network are the linear and nonlinear effects of fiber. In this paper analysis the linear and non-linear effects present in optical communication system. The performance of the optical communication system due to collective effect of FWM and SRS and due to combined effect of FWM and XPM has been discussed. Limitations of amplifier and its optimal location have also been discussed. In this paper the performance evaluation based on Q-factor vs transmitted power for FWM-XPM, SRSFWM, SRS-XPM and SRS-XPM-FWM-ASE nonlinearity in optical communication for 8 channels and 16 channels communication system.
