  • Optical amplification device with automatic gain control
    Patent number: 7016105
    Abstract: A method of automatic gain control for use in an optical amplification device comprising a variable optical attenuator and an optical amplifier connected downstream of the optical attenuator includes the steps of measuring the power at the input of the amplification device, determining the number of channels at the input of the amplification device as a function of the measured power knowing the attenuation value of a span upstream of the device, and modifying the gain of the amplifier as a function of the number of channels determined in this way.
    Type: Grant

    Date of Patent: March 21, 2006
    Assignee: Alcatel
    Inventors: Guy Balland, Alice Michaud, Emmanuel Rossi, Frank Bruyere, Jacques Pochet, Christophe Trouiller
