Abstract: Raman Amplifiers (RAs) are a group of amplifiers which have various applications in optical communications. Data transmission media utilized for RAs are optical fibers operating in nonlinear regime. We present the performances and characteristics of RAs by utilizing a set of coupled differential equations and numerical simulations. Two types of fibers with different gain characteristics, germanium-doped and silica fibers are used in our numerical simulations. So, the optimum initial values of the pump powers for a system with 10 pumps are recalculated and optimized again. We did our simulation to have a flat gain and low noise characteristics. Another aspect of the fiber media is their effective areas and we studied the effects of this parameter on the net gain of the RAs. Finally, the noise figure computations are discussed for our 10 pumps bidirectional amplifier which is optimized.
