Abstract
A method of operating a noise compensating gain controller in an optical amplifier to avoid overshoot of a selected gain level during amplification transients is provided. The first step of the method includes the computation of a difference in the amount of amplification necessary to bring the combination of the signal and noise component forming the optical output to the selected gain level. Next, a computation is made of an adjustment of the amplification difference that is necessary to bring the signal component of the output to the selected gain level at a post-transient, steady-state condition of the optical input. In the final step, the amplification is changed in accordance with the computed difference in the amount of amplification either prior to or simultaneously with the adjustment to this difference.
