我们提出并实验证明了一个集成的无源光网络监测系统的故障检测和定位。故障检测技术是基于对每个单根光纤光栅产生的反射光谱的识别，可以支持大容量用户光纤故障监测。故障定位方法采用光功率计测量的两个不同的总接收功率来求解所建立的方程，并与OTDR测量结果进行比较，显示出较好的准确性。故障检测和定位是分开进行的，但共用同一个发射器模块。附加模块的引入确保了故障排除不会影响其他正常的用户数据通信。我们还研究了故障检测技术的动态范围要求和故障定位方法的测量误差。计算结果表明，识别装置所需的动态范围可以保持在较小的范围内，使用高精度的光功率计可以减小测量误差。所提出的监测系统可以在成本敏感的无源光网络市场中同时提供大容量的故障检测技术和高精度的故障定位方法。
We propose and experimentally demonstrate an integrated passive optical network monitoring system for fault detection and localization. Fault detection technology is based on the recognition of reflection spectrum generated by each single fiber Bragg grating, which can support large-capacity user fiber fault monitoring. Fault localization method uses two different total received powers measured by an optical power meter to solve the established equation, and it shows a good accuracy compared with the OTDR measurement results. Fault detection and localization are carried out separately but share the same transmitter module. The introduction of the additional module ensures that the troubleshooting does not affect other normal user data communication. We also investigate the dynamic range requirements of the fault detection technology and the measurement error of the fault localization method. The calculation results show the required dynamic range for the recognition device can be maintained within a small range and the use of high-accuracy optical power meter can reduce the measurement error. The proposed monitoring system can simultaneously provide a large-capacity fault detection technology and high-accuracy fault localization method in a cost-sensitive passive optical network market.
