Erbium Doped Fiber Amplifier (EDFA) is an optical amplifier that uses a doped optical fiber as a gain medium to amplify an optical signal. A single EDFA is used for simultaneously amplifying many data channels at different wavelengths within the gain region. The signal which is to be amplified and pump power is multiplexed into the doped fiber and the signal is amplified because of the interaction with the doping ions. In this paper various EDFA pumping schemes are studied and analyzed. The analysis is made for high pump power 200mW to 600mW. Standard Erbium Doped Fiber of length 16.2m is used. Input signal power is set at -34dBm at 1550nm. Output power calculated is in the range of 15 to 25dBm, while the noise figure varied between 4.37 to 7.24 dBm. Among the different pumping method it is found that bi-directional pumping method shows best results.
