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 24±0.299dB from 1546nm to 1558nm band of wavelength with noise figure (NF) <6dB and bit error rate (BER) <10-9 for 16-channels simultaneous amplification in a single stage EDFA. A WDM system which includes an EDFA is modeled and obtained maximum uniformed gains
