Abstract
With theoretical modeling, we optimize the fiber design for distributed erbium-doped fiber amplifiers which maintain a constant signal level across 10 - 100 km lengths. A constant signal level is maintained by fully inverting an amplifier with very low doping concentrations in the 10 - 50 ppb range. Included in the analysis are the pump wavelength, pumping configuration, erbium doping concentration, noise, temperature effects, macrobending loss and chromatic dispersion. We found that the optimum design would consist of a V value of 1.775 with a corresponding doping concentration of approximately 22 ppb.
