Paper Abstract

A comprehensive model is used to analyze gain and noise performance for Erbium doped fibre amplifiers pumped at 980 and 1480 nm. A minimum noise figure is shown to be given by emission to absorption cross section ratios at both pump and signal wavelength. The deterioration from the minimum noise figure in each pumpband is shown mainly to be due to the presence of the counter propagating Amplified Spontaneous Emission. It is shown that for the preamplifier the fibrelength for optimum receiver sensitivity is up to 50 % smaller than the maximum gain fibre-length
