Improving Communication Performance Through Fiber Amplifier EDFA
Due to the development of fast and extensive data communication methods, typical erbium-doped fiber amplifiers (EDFA) have recently gained much interest. The main advantage of EDFA is its ability to build a system with a broad band.

SURVEY OF HYBRID EDFA/RAMAN IN C AND L BANDS
Revista Ingeniería, Matemáticas y Ciencias de la Información, 2017 Optical amplifiers have had a breakthrough in recent years. Initially, amplification of optical signals was performed passing the optical signal to the electrical domain, then the amplified signal back again to the optical domain.

Electronics Letters, 1999 A study is presented of four-wave mixing (FWM) in L- and C-band EDFAs. From experiments, it has been observed that FWM scales with the length of Er-doped fibre. It is shown theoretically that FWM crosstalk from EDFAs considerably exceeds that from NZDSF fibre in DWDM L-band systems and leads to a penalty of up to 1 dB in terms of the Q parameter.
