An EDFA works by adding erbium ions to a short piece of fiber and exciting them with a small pump laser at 980 or 1480 nm. When the telecom signal (around 1550 nm) passes through, the excited erbium atoms boost its intensity without converting it to electricity. Erbium-doped fiber amplifiers (EDFAs) are the most important fiber amplifiers for long-range optical fiber communications, efficiently amplifying signals in the 1. Before EDFAs, every long fiber link needed costly optical-to-electrical-to-optical. We report on the development of an Erbium amplifier operating at 1550 nm with an output power of 115 W for 500 hours and power variation of less than 1% when run under an open loop, constant-current configuration. To achieve this level of stability, a Raman pump laser system was configured to. EDFA (Erbium-Doped Fiber Amplifier) is an optical device used to compensate optical signal attenuation caused by fibers and components, to increase optical transmission distance.
