Simulation of fiber optic communication line with Raman amplifier

This paper describes a methods of simulation of fiber optical communication line with Raman amplifiers. Proposed method allow to consider impact of nonlinear effects, dispersion effects, noise from double Rayleigh backscattering (DRB) and amplified spontaneous emission (ASE). In paper scheme with forward pump Raman amplifier was analyzed and different types of fiber was used for simulation. Single and multichannel system was simulated. Estimation of transmission system performance was made by Q-factor.
