The paper demonstrates a gain-flattening performance characteristics of Erbium-Doped Fiber Amplifier (EDFA) for C-band application ranges from 1525 nm to 1565 nm. This technique was modeled with eight channel transmissions associated with Wavelength Division Multiplexing that comprises of gain uniformity. Signal amplification process at the input was accomplished of Erbium doped fiber with Non-Uniform Fiber Bragg Grating (FBG) and Amplified Spontaneous Emission (ASE). These results showed that the stimulated emission was associated with the least flat amplification and inversely proportional relationship between output signal power and the space separating the gratings in Fiber Bragg Grating. The performance analysis also resembled the dependency of gain on the Doping Concentration, Input Powers, Length of Fibers, Doping Profile of the Erbium Doped Fiber and Windows Wavelength of input signal, which in turn increases the input and output signal power. However, after a reduction in the resultant gain, low noise power of about -60 dBm existed. Lastly, a comparison of different methods for gain flattening was conducted and the results showed high gain modeled with EDFA using FBG. The simulator Optisystem 14.0 was also used to investigate the characteristics of the C-band EDFA using FBG.
