A novel all-optical feedback automatic gain control scheme for remote optically pumped amplifiers has been proposed. The static and dynamic gain control characteristics of the remotely pumped erbium-doped fiber amplifier have been experimentally clarified. The maximum gain excursion has been successfully reduced by a factor of ~10 from 2.1 dB to ~0.2 dB using the proposed gain control scheme.
