Abstract:In this study the authors present a novel technique for control of signal power transients caused by signal add/drops in optical communication networks with erbium-doped fibre amplifiers (EDFAs). The approach utilises the electronic automatic gain control that combines both feedback and feedforward control of EDFA. Feedback control is non-linear integral control and feedforward control is a steady-state gain scheduling technique. The feedback non-linear control requires information about the average inversion … Show more
