本文提出了一个精确描述分布拉曼增益系统中放大自发辐射噪声的模型。数值模拟与实验结果相印证。我们的模型是用来研究信号和噪声之间的相互作用介导的光纤非线性不同的传播制度。它示出，对于大于120公里的距离和中等信号功率，高于6毫瓦，噪声统计显著偏离高斯分布。
A model accurately describing amplified spontaneous emission noise in systems with distributed Raman gain is presented. Numerical simulations are corroborated with experimental results. Our model is used to study the interaction between signal and noise mediated by fiber nonlinearities for different propagation regimes. It is shown that for distances longer than 120 km and moderate signal powers, higher than 6 mW, the noise statistics deviates significatively from the Gaussian distribution.
