Abstract
The transient responses of Er-doped fiber amplifier (EDFA) to fast channel adding/dropping processes have been studied and analyzed. The result shows that the speed in which we can control EDFA with a feedback circuit is limited by the physical processes involved in the amplification. We demonstrated that with the combination of electrical feedforward and feedback, the power excursion caused by fast channel adding/dropping processes can be minimized.
