Method for controlling an erbium doped fiber amplifier (EDFA) and amplifier arrangement
Abstract:
The invention refers to a method for operating an amplifier with a first amplifier stage (A1) and a second amplifier stage (A2), pumped by a single pump light source (11) generating a primary pump signal (SPUMP), which is split into first pump signal (S1) and a second pump signal (S2) according to a variable splitting factor (α) for pumping the first amplifier stage (A1) and the second amplifier stage (A2) respectively. The splitting factor (α) is varied to achieve an optimized noise figure.
Abstract(Chinese):

本发明涉及一种用于操作具有第一放大器级（A1）和第二放大级（A2）的放大器的方法，该放大器级由泵浦光源（11）泵送，该泵浦光源产生初级泵浦信号（SPUMP），该主泵浦信号被分成 根据用于分别泵浦第一放大级（A1）和第二放大级（A2）的可变分频因子（α）的第一泵浦信号（S1）和第二泵浦信号（S2）。 分解因子（α）是变化的以实现优化的噪声系数。
