Diminution of ASE Noise in Erbium Doped Fiber Amplifiers with Fabry Perot CW Laser Source in Single Pumping Technique

The scope of this paper is to decrease the ASE Noise in the simulation model of EDFA with little amount of FPCWL source power using single pumping method. . The simulation model consists of FPCWL source with wavelength (1550nm), pumping CW Laser source (with wavelength 980nm) and Filter. The resulting model accurately represents EDFA Gain and optimized output signal power and reduces the ASE noise when input signal power decreases from 0.1mw to 0.01mw. Simulation results shows that by choosing careful fiber length 20m and pump power 1mw in single pumping gives ASE noise 0.005mw at signal input 0.1mw and 0.0042mw at signal input of 0.01mw.
