A serial hybrid optical amplifier composing of two amplification stages of erbium-doped fiber (EDF) amplifier covered C-band window and Raman fiber amplifier (RFA) covered L band window demonstrated. In this paper, the optimizations were done to obtain the optimum pump power and optimum pump wavelength for Raman amplifier in order to achieve a flat gain bandwidth at wideband amplification. The DCF (dispersion compensation fiber) that used in Raman amplifier pumped by two Raman pump units (RPU). RP1 at 1410 nm with 700 mw is used for S band region, and the RP2 is 1490nm with 350mw is chose to get an amplification at L-band region. The system performance was analyzed in term of overall gain, noise figure, gain variation and gain bandwidth using optisystem7.The proposed design of serial hybrid fiber amplifier (SHFA) provides a flat gain bandwidth of 85 nm ranged from 1525 to1610 nm within 3-dB gain flatness. Over 18.5dB average gain is achieved, and the corresponding noise figure is 5.04dB. The performance evaluated at the optimum parameters with a small input signal power of -30dBm.
