<P>从增益的公式公式可以看出来，增益实际上是和泵浦光功率，输入光功率以及光纤长度（泵浦光在光纤中的能量密度分布）有关，而我实际可以控制的只有泵浦光功率，增益钳制就是通过检测入光/出光来控制泵浦的驱动电流，控制的精度取决于电路电流控制的精度；</P> <P>而泵浦驱动和EDFA的性能关系就要看模块了，也就是诸如增益平坦度，小信号增益，饱和增益等，实际线性范围是通过控制泵浦强度来控制的。</P> <P>如你所说，其中一个通道光功率发生变化，整体入光功率发生变化了，这是通过控制泵浦激光器泵浦功率使得出光功率/如光功率维持稳定值，但对于近饱和和小信号入光时，需要再调整，这时的入光出光检测已经是不准的了（小信号基本与ASE噪声一个水平了），饱和的状态是在怎么增大泵浦功率出光也是达不到所以，一般的饱和增益降低一半作为额定工作状态。</P> <P>对于不同波长的光在一定范围内入光出光近似于线性，这可以根据G～Pin的关系来考察（具体的公式我忘记了），粒子数的消耗应该是动态的平衡，某一波长消耗的多了，泵浦就会多补偿一些；但是再实际应用中还是使各波长的光功率等同，否则就像你说的要加增益平坦滤波器了。</P> <P>粒子数反转水平可以根据英光谱考察，既是没有激发信号光，自发辐射也会发光的，要维持一定的动态平衡，如果荧光光谱是平坦的，增益谱在一定范围内基本也是平坦的。</P> <P>哇啦哇啦说了一堆，不只说明白没有？！</P> </td></tr></table> </div> <div id="comment_289371" class="cm"> </div> <div
