Abstract :
Analysis of DWDM system using EDFA in C band (1530 nm to 1560 nm. Optimum results of Gain, Noise Figure, Gain Flattening and BER are obtained by varying input channel power, channel spacing, EDFA length, Pump Power and Erbium concentration. Gain of EDFA is proportional to the difference in population of intermediate level and lower level. The population inversion can be controlled by proper choosing of fiber length and injected pump power to EDFA. Two methods of pumping are discussed- direct pumping at 1480 nm and indirect pumping at 980 nm. Results are obtained at 980 nm only. Results were obtained using optical simulation software.
