本文研究了利用频谱整形放大自发辐射噪声（SS-ASE）作为模拟光纤传输系统中干扰信道的方法。结果表明，使用SS-ASE导致一个稍微悲观的性能相对于使用传统调制的干扰信道在非线性制度。由于SS-ASE的高斯性质，额外的非线性干扰噪声（在被测信道上）已经使用整个C波段（4.5 THz）的高斯噪声（GN）和增强型GN（EGN）模型的组合进行了计算，并通过实验证明，提供了传输性能的下限。
The use of spectrally shaped amplified spontaneous emission noise (SS-ASE) as a method for emulating interfering channels in optical fibre transmission systems has been studied. It is shown that the use of SS-ASE leads to a slightly pessimistic performance relative to the use of conventionally modulated interfering channels in the nonlinear regime. The additional nonlinear interference noise (on the channel under test), due to the Gaussian nature of SS-ASE, has been calculated using a combination of the Gaussian noise (GN) and enhanced GN (EGN) models for the entire C-band (4.5 THz) and experimentally shown to provide a lower bound for transmission performance.
