Abstract
While polarization scrambling increases the Q seen over ultralong EDFA links, the improvement is limited by the generation of amplitude ripple, which acts to reduce the mean and increase the fluctuations in Q. It is shown that by choosing a frequency close to the erbium dynamic gain response cutoff, the AM is suppressed and a better Q improvement is obtained. This approach yielded a 1.7 dB increase in mean Q on a 6300 km system, with a significant reduction in the standard deviation of the Q variations.<>
