摘要

提出了一种基于Wilcoxon符号秩检验的无源光网络故障定位方法。该方法与现有的依赖于时域识别的PON监测技术无缝集成,能够从时域轨迹中提取潜在特征,用于故障检测。它有效地解决了传统方法无法利用振幅数据进行故障定位的一个关键缺陷。我们的方法准确地识别故障点数据区域对应的特征,并通过构建模型将这些位置映射到获得的时域轨迹上,从而实现对轨迹数据的二次分析。这一创新克服了大多数现有PON监测技术固有的局限性,即只能检测故障而不能定位故障,实现了故障定位,而不需要在原有的PON监测系统中增加额外的组件。在基于时域识别的PON监测系统上进行了实验验证,验证了该方法的可行性。此外,我们将我们的方法得到的结果与OTDR测试的结果进行了比较,证实了我们的方法达到了很高的定位精度,只有64个平均值。由于用于故障定位的数据来源于故障检测阶段本身,而不是外部来源,因此该方法大大简化了集成设计,提高了测量效率。这种具有成本效益的解决方案在PON市场上具有重要的前景,在增强故障定位能力方面提供了广泛的适用性和可观的价值。

Cost-efficient PON fault localization utilizing Wilcoxon signed rank test
We introduce a novel fault localization method for passive optical networks (PONs) based on the Wilcoxon signed rank test. This approach seamlessly integrates with existing PON monitoring techniques that rely on time-domain recognition, enabling the extraction of latent features from time-domain traces used in fault detection. It effectively addresses a key limitation of traditional methods, which are unable to utilize amplitude data for fault localization. Our approach accurately identifies features corresponding to fault point data regions and maps these positions onto acquired time-domain traces through a constructed model, thereby enabling secondary analysis of the trace data. This innovation overcomes the limitations inherent in most existing PON monitoring techniques, which can detect faults but not localize them, achieving fault localization without the need for additional components in the original PON monitoring system. Experimental validation conducted on a PON monitoring system based on time-domain recognition demonstrates the feasibility of the proposed approach. Furthermore, we compare the results obtained from our method with those from OTDR tests, confirming that our approach achieves high localization accuracy with only 64 averages. Since the data utilized for fault localization is derived from the fault detection phase itself rather than from external sources, this method significantly facilitates integrated design and enhances measurement efficiency. This cost-effective solution holds significant promise in the PON market, offering extensive applicability and considerable value in enhancing fault localization capabilities.
