Subject Area:

Physical Sciences and Engineering

Abstract:

The Gain flattened EDFA plays a major role for modern WDM optical application. Use of a Low Pass Cosine Roll OFF Filter and tuning numerical aperture and fiber length for a specific pump power optimizes the gain flattening. The design is simulated using OPTISYSTEM software. The gains are flattened within 29.61dB-30.401dB from 1546nm-1558nm band of wavelength with noise figure (NF) < 5.5dB and bit error rate (BER) <10-36for 16 channel simultaneous amplification in a single stage EDFA.
