摘　　要：针对人工检测纤芯通信质量不易检测的特点,结合单位业务实际和对纤芯通信质量检测管理需求,设计了一套基于OTDR的光纤传感节点感知光缆纤芯质量的光纤纤芯质量检测系统。该系统主要采用多通路OTDR光缆监测,综合应用光时域反射、计算机和地理信息系统技术,利用移相采样技术和跨阻偏压可变接收机技术提升了OTDR模块的性能并有效地控制了成本,实时获得被测光缆纤芯通信质量信息,有效提高光纤通信网的可靠性和使用效益。Aiming at the difficulty of checking fiber core communication quality by hand,a set of optical fiber core quality detection system based on optical time-domain reflectometer（OTDR） was designed,in combination with the actual business and the demands of fiber core communication quality detection management,in which optical fiber sensing node can perceive the quality of optical fiber core. Multi-channel OTDR optical cable monitoring,the technologies of OTDR,computer and geographic information system are adopted comprehensively in this system. The performance of OTDR module was promoted by using phase shift sampling technique and transimpedance bias voltage variable receiver technique,and the cost was controlled effectively. The communication quality information of the detected optical fiber core was obtained in real time. The reliability and utilization benefits of optical fiber communication network are improved effectively.
