海底光缆敷设在极其复杂的海洋环境中，极易受到各种外界因素的破坏，其中锚害是海底光缆通信的最大威胁。针对现有海底光缆监测技术的局限性，提出将双 M-Z(马赫-曾德尔)分布式光纤振动传感技术用于海底光缆的在线监测。通过理论推导建立了分布式海底光缆监测系统传感、定位的数学模型；并通过综合利用海底光缆路由雷达监测系统，有效解决了实用中监测系统可能存在的虚警问题，提高了系统的可靠性。

Laid in the complex ocean environment,the Submarine Optical Fiber Cable (SOFC)is vulnerable to external dama-ging factors,especially the anchor damage.In view of the limitations of the existing monitoring technologies,this paper propo-ses to apply the dual M-Z interferometer-based distributive fiber vibration sensing technology to the on-line monitoring of the SOFC and establishes a mathematical model for the system sensing and positioning by theoretical derivation.Furthermore,by combining with the SOFC routing radar surveillance system,it effectively solves the possible problem of false-alarm in practical monitory systems and improves the system reliability.
