Design of optical power monitoring system for optical nodes based on LoRa

光纤网络的信号传输状态可以通过光功率值来量化体现,针对现有的光功率监测系统设计中存在的缺陷,提出了一种基于LoRa技术的光节点光功率监测系统设计方案。分别对监测终端和接收端硬件及软件进行了设计,并且在PC端进行了Labview数据显示和故障告警设计。通过测试实验表明,该设计具有通信距离远、功耗低、网简单、方便等优点,可实现对远程光纤线路节点光功率监测和故障告警。

The signal transmission state of optical fiber network can be quantified by the optical power value.This paper proposes a scheme of optical power monitoring system based on LoRa technology,from the aspect of the shortcomings of the existing optical power monitoring system design.With considering the hardware and software of the monitoring terminal and receiver,the data display and fault alarm are also designed in the Labview at the PC terminal.The experimental results show that the proposed system has the advantages such as long communication distance,low power consumption,easy-deployment and convenient and so on.It could monitor the optical power of the remote optical fiber line nodes and alarm.
