摘　　要：为解决传统通信机房和数据中心中光配线架光纤跳线布线不规范、光缆冗余过多的问题,提出一种光纤配线路由智能排查系统。首先,采用高性能、低成本的微型控制器STM32芯片控制光收发系统,通过电-光-电信号的数据收发实现光纤配线路由排查;然后,设计基于通用运算放大器LM358、中继技术进行定量放大和中继处理;最后,采用Opti System软件对系统的性能进行仿真测试。测试结果表明:系统的动态范围最大达到9.24 d B,能实现光纤传输距离为46 km的排查功能;同时,系统中再生信号的质量得到了提高,能有效延长系统传输距离。In order to solve the problems of irregular wiring of optical fiber jumpers in optical distribution frames and excessive redundancy of optical cables in traditional communication rooms and data centers, an intelligent checking system for optical fiber routing is proposed. Firstly, the optical transceiver system is controlled by a high-performance and low-cost microcontroller STM32 chip, and the optical fiber routing is checked through the electro-optical signal data transceiver. Then, based on general operational amplifier LM358 and relay technology, quantitative amplification and relay processing are designed. Finally, the Opti System software is used to simulate the performance of the system. The test results show that the maximum dynamic range of the system is 9.24 dB, and it can achieve the troubleshooting function with an optical fiber transmission distance of 46 km. At the same time, the quality of the regenerated signal in the system has been improved, which can effectively extend the transmission distance of the system.
