掺铒光纤放大器增益平坦度分析及优化

Analysis and Optimization of the EDFA Gain Flatness

EDFA的增益平坦度具有波长依赖性,所以当用于WDM系统时,对不同波长的增益将有所差异。在本文中,列举了一个关于EDFA的增益平坦度优化的例子。通过优化光纤长度和泵浦功率,可以使掺铒光纤放大器的增益平坦。从而满足WDM系统对增益平坦度和输出功率的要求。

The gain flatness of EDFA has a wavelength-dependent, so when for WDM system, the gain will vary for the different wavelengths. In this tutorial, we provide an example of the gain flatness optimization type. The gain of the EDFA will be flattened by optimizing the fiber length and pump power, to meet the gain flatness and output power requirements for a WDM system.
