    • A Self-adapting feed forward control apparatus in an optical amplifier includes a feed forward controller for collecting target output power (Pout) and controlling drive current of a pump laser in the optical amplifier; a feedback controller for calculating target output power (Pt) and collecting actual output power (Pout), calculating deviation between (Pt) and (Pout), and controlling drive current of the pump laser; and a parameter estimator for collecting power target, output power and summation of output signal of the feed forward controller and feedback controller, and estimating the feed forward parameter and updating the parameter of the feed forward controller. The apparatus can automatically correct the feed forward control parameters according to the variation of EDFA parameters due to environmental condition changes or device aging.
    • A光放大器中的自适应前馈控制装置包括用于收集目标输出功率(Pout)并控制光放大器中的泵浦激光器的驱动电流的前馈控制器; 用于计算目标输出功率(Pt)和采集实际输出功率(Pout),计算(Pt)和(Pout)之间的偏差并控制泵浦激光器的驱动电流的反馈控制器; 以及用于收集前馈控制器和反馈控制器的功率目标,输出功率和输出信号的总和的参数估计器,并估计前馈参数并更新前馈控制器的参数。 根据环境条件变化或器件老化,EDFA参数的变化可以自动校正前馈控制参数。
