Abstract

We analyze the performances and characteristics of multiwavelength Raman amplifiers that are designed in backward or bi-directional pumping which can be used in dispersion compensator and low noise amplifiers and compare several configurations of a Raman amplifier system. The results show that amplitude spontaneous emission (ASE) in backward pumping is less than bi-directional pumping with improved noise figure. In addition, for backward and bi-directional pumping the system ability can be better by appropriate design of pump powers and wavelengths of system.
