As light pulses propagate along the optical fiber, their energy dissipates. Beyond a certain distance the number of photons in pulses becomes too small to be detected. The optical pulses in fibers are energized by utilizing optical fiber amplifiers. The rapid growth of the internet and data traffic in optical fiber communication networks has stimulated the study of wideband optical amplifiers. Widening the bandwidth of fiber amplifiers is the primary issue in enlarging the capacity of wavelength-division multiplexed (WDM) transmission systems. This may be achieved by hybrid Raman/Erbium-doped fiber amplifiers. In this paper hybrid Raman/Erbium-doped fiber amplifier is simulated and almost flat gain of 21 dB is obtained for 1530-1565 nm wavelength range.
