Abstract(in English) | In order to develop superior high-speed automatically gain controlled (AGC)EDFA, we study gain dynamics of erbium doped fiber amplifiers(EDFA)when the input channel count is changed.It has been found that the dynamic gain excursions of the surviving channels cannot be suppressed even if the pump power is adjusted at the same time as the input channel count change in the EDFA pumped at 974nm.Based on this result, we propose the high-speed AGC-EDFA employing an optical delay line to reduce the dynamic gain excursion. By employing the optical delay line in the high-speed AGC-EDFA pumped at 974nm, the maximum dynamic gain excursions have successfully been reduced. In five cascaded EDFA chains, the maximum dynamic gain excursion of about 1dB is realized. |
