  • METHOD AND SYSTEM FOR CONTROLLING THE OUTPUT OF AN OPTICAL PUMP ENERGY SOURCE
    Publication number: 20030081298
    Abstract: The amplification and noise level of an optical communication signal is controlled by providing a feedback loop to adjust the energy level of an optical pump energy source used to amplify the communication signal. The communication signal is combined with an optical control signal outputted by the pump energy source. The communication signal is amplified as the combined signals pass through an erbium doped fiber optic cable energized by the control signal. The amplified communication signal is then separated from the control signal. The control signal is in a depleted state (substantially residual pump energy) after traveling through the length of the erbium doped fiber optic cable. A feedback signal, used to adjust the energy level of the control signal, is generated based on the amplified communication signal and the depleted control signal.
