Another technique to amplify an optical signal is to use an all optical amplifier (OFA). It consists of a fiber segment doped with erbium and pumped with light of wavelength at 980 or 1480 nm.
Using a simple two-level model for the EDFA assumes that ASE and excited-state absorption are negligible. Also, this model assumes the top excited energy level empties instantly (negligible excited
