Gain of L-band EDFA has been analyzed. The effect of change in the length of doped fiber and the use of various pumps on EDFA has been examined. EDFA exhibits a maximum gain of 16.80 dB at 188.2 THz at 980 nm pump (length of doped fiber = 150m, pump power = 100 mw) and a maximum gain of 20.53 dB at 191 THz at 1480 nm pump (length of doped fiber = 150m, pump power = 100 mw).The overall noise figure is round 4 dB for both 980 nm and 1480 nm pump. Gain of L- band EDFA increases with the length of the fiber and noise figure also increases with increase in length of fiber keeping pump power constant.
