摘　　要：为了探讨复杂海洋环境下对海底光纤运行状态进行在线监测的最佳方式,文章提出了基于SDH光通信网络技术的光发送接收单元与网络管理系统相互协调的研发技术路线,经过光单元衰耗指标与灵敏度计算调整,及光纤迂回串接虚拟监测链路的联合调试、SDH网络管理功能的二次开发应用,实现了海底光纤实时在线监测和异常情况远程告警功能,具有投资省、见效快、简单实用等特点,创新和实用化效果显著,经进一步充实完善后,在众多海岛环境下对海底光纤进行状态检修等领域推广应用前景广阔。In order to investigate the best online monitoring method for the running status of submarine optical fibers, this paper presents a technical route for research and development by inter-coordinating between optical sending/receiving units and network management system based on SDH optical communication network technology. Through calculation and adjustment of optical unit attenuation index and sensitivity, the system debugging of virtual monitoring link on circuitous concatenation of optical fibers, the secondary development and application of SDH network management function. It implements the functions of real-time online monitoring for submarine optical fibers and remote alarm in case of abnormality. This system features low investment cost and quick return, simple and functional, with significant innovative and practical effect. After being enriched and improved, it shows broad application prospect for the condition maintenance of submarine optical fibers in marine environment.
