Abstract
A theoretical investigation of reduction of relaxation oscillations in optical automatic gain clamped erbium-doped fibre amplifiers (EDFAs) with fast electronic feedforward is reported. The results showed that the speed of control electronics or corresponding response times, 4, 6 or 8 μs, bounded the reductions of the relaxation oscillations for 40, 20 or 10 channels, respectively
