“…The system is analyzed for gain spectrum at different values of rst-stage lengths and constant pumping power, while second-stage length of 4m and pump power of 400mw, the results are shown in Table (3) and Fig. (4). It can be observed that, at the same pumping power the gain is increases as EDFA-length increases with a small value and the best value of gain variation is by using 4m rst-stage length.…”

“…In [3] by using EDFA with 980nm backward pump con guration, 4m-length, 0.8nm channels spacing, the gains are attened within 24 ± 0.299dB and average NF of 6dB were obtained. In [4] using EDFA, the gains are attened within 33.57dB-33.97dB with gain atness of 0.39dB, NF < 7dB, Q-factor 14.78 and BER < 10 − 22 . In [6] the authors use the hybrid EDFA-Raman ampli er which have eight counter pumps, best results are obtained at gain variation is 2.46dB and NF of (4.32-5.36dB).…”

The gain flatness of amplifier is very important parameter in optical network systems when wavelength division multiplexing (WDM) device used in the transmission of many channels in the system. This paper seeking toward minimum gain flatness of the amplifier. In this paper several methods are used to obtain the optimum value of gain variation and get the maximum gain uniformity between sixteen channels in C band. We optimize the length and pump power of EDFA, and used a lot of stages of EDFA and used hybrid amplifier with EDFA and Raman fiber amplifier (RFA) and optimize the number of pump wavelengths of the RFA. The gains are flattened within 37.65 ± 0.0445 dB from 1546nm to 1552nm with noise figure (NF) within 3.56 dB, Q-factor of 9.97 and BER of 9.3×10− 24 at hybrid 980-EDFA-RFA. A comparison between the several configurations is made.

“…Although EDFA systems are still needed to have equalized gain spectrum order to obtain similar signal to noise ratio and uniform output power (6). Various methods are there in designing a flat spectral gain of EFDA, by controlling the pumping power and length of fibre (7), by using a proper notch filter, or by acousto-optic tunable filter (8). Flatness can be improved by tuning aperture of low pass filter by controlling fibre length and pump power (9).…”

The Gain flatness of EDFA plays an important role for Wavelength Division Multiplexing (WDM) optical application. Equalizing of an amplifier's gain spectrum is essential for balancing the channel powers to achieve error free detection of the signals transmitted through the optical link. The purpose of this paper is to improve the gain unevenness for each channel in order to equalize the amplitude in a Wavelength Division Multiplexing (WDM) system. And also various filters have been taken under study to find its effect on the output. The design simulation aided by Optisystem 12 software. From the analysis it has been found that the gain flatness is improved by optimizing the pump power, pump wavelength and fiber length. The optimized value of EDFA to achieve maximum gain flatness under different filters are presented. The gain are flattened within 32.75dB-33.67dB from 1546 nm-1558 nm band of wavelength with noise figure (NF) < 7dB, output power 15 dB, Bit Error Rate (BER) < − & Quality factor is 14.64. By these above parameters, gain flatness of 0.3dB can be achievable.
