摘要

对已部署的骨干网络的监测数据显示，许多光路的传输质量（QoT）波动很大，范围超过 1 dB。在本文中，我们研究了这样一种假设，即所显示的波动源于偏振相关损耗（PDL）的异常，相当于一个大的 PDL 元素。我们最终提出并通过实验测试了一种闭环自动化系统，旨在将受这种 PDL 异常影响的光路的 QoT 稳定在最大水平。

On the detection, modeling, and mitigation of anomalous QoT fluctuations in optical networks

Monitoring data from deployed backbone networks shows that many lightpaths present large fluctuations of their quality of transmission (QoT), beyond 1 dB in range. In this paper, we investigate the hypothesis that the evidenced fluctuations stem from anomalies in polarization-dependent loss (PDL), equivalent to one large PDL element. We eventually propose and experimentally test a closed-loop automation designed to stabilize the QoT at a maximal level for lightpaths impaired by such a PDL anomaly.

期刊介绍： The scope of the Journal includes advances in the state-of-the-art of optical networking science, technology, and engineering. Both theoretical contributions (including new techniques, concepts, analyses, and economic studies) and practical contributions (including optical networking experiments, prototypes, and new applications) are encouraged. Subareas of interest include the architecture and design of optical networks, optical network survivability and security, software-defined optical networking, elastic optical networks, data and control plane advances, network management related innovation, and optical access networks. Enabling technologies and their applications are suitable topics only if the results are shown to directly impact optical networking beyond simple point-to-point networks.
