  Abstract

In this paper, we have shown the gain recovery time of erbium-doped fiber amplifier(EDFA) in WDM add/drop networks can be reduced to less than 3μsec by employing disturbance observer technique with PID controller which is based on 3-level EDFA model. The 3μsec transient time is the fastest one ever reported and it is about 1% of 250μsec previously obtained from disturbance observer technique with PI controller which was based on 2-level EDFA model and it is also less than 200μsec of commercially available EDFAs for WDM networks. We were able to obtain this result by analyzing various system characteristics as we change the parameters of disturbance observer and PID controller. If this result is applied to a commercial product, the product will do an important role in the future dynamic WDM networks.
