论文摘要
在这篇论文中,研究了在损害的背景下创建非线性干扰噪声(NLIN),以估算传输质量。特别是,研究了在测试的通道上传输过程中相邻通道(干扰物)的非线性干扰。干扰器的调制格式,干扰器的累积色散,跨度长度和通道间距被确定为在灵活的光网络的背景下影响NLIN产生的参数。 NLIN的估计是根据数值模拟结果的评估进行的,并与最近的分析传输模型(即高斯噪声模型和增强的高斯噪声模型)进行了比较。除了非线性噪声功率外,模拟还产生了有关相位和圆形噪声贡献以及相位噪声的相关时间的信息。在脉搏碰撞图片的背景下评估结果,并讨论了对传输质量的影响。
In this thesis the creation of nonlinear interference noise (NLIN) in the context of impairment aware flexible optical networks is investigated to estimate transmission quality. In particular, the nonlinear interference of neighboring channels (interferer) during transmission on a channel under test is studied. The modulation format of the interferer, the accumulated chromatic dispersion of the interferer, the span length and channel spacing are identified as the parameter influencing the generation of NLIN in the context of flexible optical networks. Estimation of the NLIN is done based on the evaluation of numerical simulation results and compared to recent analytical transmission models, namely the Gaussian noise model and the enhanced Gaussian noise model. In addition to nonlinear noise power, the simulations also yield information about the phase- and circular-noise contributions as well as the correlation time of the phase noise. The results are evaluated in the context of the pulse-collision picture and the influence on transmission quality is discussed.
