Abstract :
We compare the energy efficiency of Distributed Raman Amplifiers (DRFA) and Erbium-Doped Fiber Amplifiers(EDFA) used in long-haul transmission systems. This comparison accounts for the interaction between optical link power, signal quality (as measured by the Bit Error Rate (BER)), and the use of Forward Error Correction (FEC). We show that deploying DRFAs in some scenarios may be more energy efficient than EDFAs, despite their intrinsic requirement for higher pump powers, depending upon the link parameters.
