Optical Amplifiers for Telecommunications

Abstract

This paper reviews optical amplifier technologies for telecommunications networks. The operation and applications of erbium doped fibre amplifiers (EDFAs), fibre Raman amplifiers (FRAs), erbium doped waveguide amplifiers (EDWAs) and semiconductor optical amplifiers (SOAs) are described. The factors that influence their gain, operating bandwidths, spectral… (More)
