Abstract
A method and apparatus to perform automatic gain equalization for a lightwave communications system is described. A first amplifier amplifies an optical signal to produce a first gain curve having a first gain maxima and a first gain minima of a first period. A second amplifier amplifies the optical signal to produce a second gain curve with a second gain maxima and a second gain minima of a second period, with the second gain maxima substantially coinciding with the first gain minima.
