中文摘要: 高速、动态、智能光网络是通信网络的发展趋势。实时准确的光性能监测技术是实现网络安全高效运行的必要保障。本项目拟对动态高速光网络物理层的光性能监测技术展开研究。通过理论分析建立监测光信号性能(如光信噪比、光功率等)及光信道参数(如色度色散、偏振模色散、偏振相关损耗等)的数学模型,数值仿真其效果并对相应的参数进行优化,搭建实验平台进行实验验证及优化,最终实现整个光性能监测模块的最优设计。设计的光性能监测模块适用于动态光网络节点处信号光功率、光信噪比的实时监测以及节点之间链路的色度色散、偏振模色散及偏振相关损耗等参数的监测,同时,它还适用于各种传输速率和码型,即具有对传输码型和速率透明的特点。本项目的研究成果将对我国下一代光网络的顺利实施提供重要的理论指导和技术支持。

英文摘要: The future optical transmission network will be high-speed, dynamic and smart, which requires real-time and accurate optical performance monitoring(OPM), in order to ensure the networks operates with security and high efficiency. This project aims at reasearching the OPM technology in dynamic high-speed optical transmission networks and designing an OPM moduler located at each link end, which provids the information on channel parameters such as optical power,optical singal-to-noise ratio(OSNR), chromatic dispersion(CD),polarization mode dispersion(PMD) and polarization dependent loss(PDL), with transparency to modulation format and transmission baud rate. Based on the mathematical analysis, simulation and experimental verification, the OPM moduler will be optimizing designed. The results will provide the guidece in both theoretical and implemental ways for the deployment of the next-generation optical network.
