Abstract
In this paper, the erbium doped fiber amplifier (EDFA) is used as a booster and a pre amplifier in the dense wavelength division multiplexing system. We optimize the design parameters of the EDFA using the multi parameter optimization tools. The gain profile of the EDFA depend on the fiber length, Er3+ ion density, Er3+ doping radius at pump wavelength λp = 980 nm while the operating frequency range is 1546 nm to 1552 nm. The optimized EDFA length is found to be 8 m at 50 mW pump power which gives a maximum gain of 40 dB and 39.5 dB for co-pumping and bidirectional pumping respectively. The analysis to obtain the optimized parameters of the EDFA is done on the basis of gain, noise figure and the optical signal to noise ratio varying the input power of 0 dBm–30 dBm.
