Abstract
Official abstract text for this publication.
The present invention includes an optical amplifier and method for reducing the impact of transient events within an optical transmission system. Specifically, a positive transient power or amplifier setting adjustment limit is applied based upon a number of active channels or a current “steady state” operating condition. This adjustment limit is described in terms of a number of channels to be amplified. By controlling the adjustment limit in this manner, automatic control of the amplifier is provided for a loss of channel condition as well as for the addition of a single or few channel condition. If a larger positive transient occurs, the control will not adjust the power limit, and the positive transient power will therefore be suppressed.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for controlling an optical amplifier configured to receive a gain control signal from a controller, the method comprising: determining an anticipated number of optical channels within a multiplexed optical signal to be amplified by said optical amplifier; selecting an initial level of amplification as a function of said anticipated number of optical channels within the multiplexed optical signal and a desired power level of the resulting amplified…
