Abstract—The gain flatness of Erbium-Doped Fiber Amplifier (EDFA) is a key device for Wavelength Division Multiplexing (WDM) application in modern optical network systems. The purpose of this paper is to correct the gain non-uniformity for each channel in order to equalize the amplitude gain in a Wavelength Division Multiplexing (WDM) system. The system is simulated using Optisystem software to achieve gain flatness of EDFA through optimized fiber length and pump power. The gains are flattened within 27 dB from 1546 nm to 1568 nm band of wavelength with Noise Figure (NF) <14 dB and Bit Error Rate (BER) 10-21 for 32-channels simultaneous amplification in a single stage EDFA. A WDM system which includes an EDFA is modeled and obtained maximum uniformed gains.
