1. An amplifier for use in optical transmission fiber, comprising:

  • an amplifying fiber configured to receive power as optical energy in a plurality of pump wavelengths;

    a plurality of pump sources for providing the plurality of pump wavelengths to the amplifying fiber; and

    a controller for controlling the plurality of pump sources to supply optical energy based on amplifier performance characterized for optical signals passing through the transmission fiber and the amplifying fiber as a function of the optical energy provided in the plurality of pump wavelengths.
