为了提高光源的各项性能，设计了一系列实验，用以验证掺铒光纤长度及泵浦源功率对光源性能的影响。采用实验的方法，分析了常温情况下，由不同长度掺铒光纤的变化所导致的ASE光源输出光的光功率、中心波长及谱宽变化，得到了在不同泵浦源功率时，掺铒光纤长度的变化对整机性能的影响，以及出光光功率和谱宽变化的实验曲线，从中发现在光纤长度为22 m时，光源工作性能最佳。这对ASE光源的器件选择及系统优化具有参考价值。实验结果表明，掺铒光纤长度对1550 nm单通后向出光ASE光源的光源输出功率和谱宽性能均有影响。

It has been proved that the length of fiber has great contribution to the performance of the 1 550 nm ASE ( Amplified Spontaneous Emission) source, both on the output power and spectral width.To improve the per-formance of the source, a series of experiments is designed, and the result shows that a proper length of fiber can improve the performance of the source.Under normal temperature, we analyze the connection between the length of EDF and output power, center wavelength and spectral width of the ASE source.Finally we derive curve of the ASE source output power and center wavelength under the different EDF length, due to the change of pumping source. The results show that when the fiber is 22 m, the performance of the ASE source is the best.
