物理损伤感知的柔性光网络传输质量估计

Quality-of-Transmission Estimation in Physical Impairment Aware Flexible Optical Networks

Joschua Dilly

摘要:

在本论文中,非线性干扰噪声(NLIN)的损伤感知灵活的光网络的背景下,估计传输质量的创建进行了研究。特别地,研究了在被测信道上传输期间相邻信道(干扰器)的非线性干扰。在灵活的光网络中,调制格式、累积色散、跨距长度和信道间隔是影响NLIN生成的重要参数。NLIN的估计是基于数值模拟结果的评价,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比较。除了非线性噪声功率,模拟还产生有关相位和循环噪声贡献以及相位噪声的相关时间的信息。结果进行评估的上下文中的脉冲碰撞图片和传输质量的影响进行了讨论。

英文摘要:

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.
