The Raman amplifier makes use of stimulated Raman scattering (SRS) within the fiber, which transfers the energy of higher-frequency pump signals to lower-frequency signals.
Abstract: We compare the energy efficiency of Distributed Raman Amplifiers (DRFA) and Erbium-Doped Fiber Amplifiers (EDFA) used in long-haul transmission systems.
Pump powers of the Raman amplifier are selected using multiparameter optimization algorithm to achieve maximum gain with small ripple. The effects of varying input powers on gain,
In contrast, Raman amplifiers have less pumping efficiency at lower signal powers, therefore they require a longer gain fiber (Islam 2002).
