Paper Abstract

We investigated the gain and noise figure dependence on signal wavelength for erbium doped fiber amplifiers (EDFA) counter-pumped at 980 nm. Using a two level modeling technique, we found a good agreement between our experimental measurements and the corresponding theoretical predictions for EDFAs operating under or far from full population inversion. Finally, we describe design trade-offs between small signal gain and noise figure for a range of active fiber length EDFAs at wavelengths of 1531 nm and 1548 nm.
