We investigate via experiments and simulations the statistical properties and the accumulation of nonlinear transmission impairments in coherent systems without optical dispersion compensation. We experimentally show that signal distortion due to Kerr nonlinearity can be modeled as additive Gaussian noise, and we demonstrate that its variance has a supra-linear dependence on propagation distance for 100 Gb/s transmissions over both low dispersion and standard single mode fiber. We propose a simple empirical model to account for linear and nonlinear noise accumulation, and to predict system performance for a wide range of distances, signal powers and optical noise levels.
我们通过实验和模拟研究了无光学色散补偿的相干系统中非线性传输损伤的统计特性和累积情况。我们通过实验表明，克尔非线性引起的信号失真可建模为加性高斯噪声，并且我们证明，对于在低色散光纤和标准单模光纤上的100 Gb/s传输，其方差对传播距离具有超线性依赖性。我们提出了一个简单的经验模型来解释线性和非线性噪声累积，并预测在广泛的距离、信号功率和光噪声水平范围内的系统性能。
