Raman fiber amplifier （ rfa ） is a kind of optical amplifier that can amplify signal light directly through nonlinear interaction of high intensity pump and signal light in fiber. whereas the spectrum of raman gain coefficient of optical fiber is not flat, the gain of signal light with different wavelength induced by a single pump is rather different, when wavelength division multiplexing ( wdm ) signal light is amplified by a single pump, the gain spectrum of the wdm signal light is not flat. the flatness of the wdm signal light has important impact on the optical signal - to - noise ratio ( osnr )
