摘要

提出了一种传感距离超过300公里的干涉式分布式光纤传感系统。该系统采用双向泵浦拉曼光纤放大器与双向EDFA相结合，无需使用直列继电器放大器。通过对系统内干涉光传输的分析，确定了有效解调相位所需的最小信噪比，并实验量化了相应的传感光纤损耗。系统采用超低损耗G654E单模光纤，在300 km范围内实现无信号退化的高性能传感，定位误差小于8 m。据我们所知，这是目前最长的分布式光纤传感系统，没有直列中继器。该系统在周边安全和海底电缆监控等领域提供了潜在的应用。

Ultra-Long-Distance Interferometric DOFS Over 300 km Without In-Line Repeater

An interferometric distributed optical fiber sensing system with a sensing range over 300 km is proposed. This system employs Raman fiber amplifier with bidirectional pumping in conjunction with a bidirectional EDFA, without the use of in-line relay amplifier. Through an analysis of the interference light transmission within the system, the minimum SNR required to effectively demodulate the phase is determined, and the corresponding sensing fiber loss is experimentally quantified. By utilizing ultra-low-loss G654E single mode fiber, the system can achieve high-performance sensing without signal degradation within the 300 km range, and the positioning error is less than 8 m. To the best of our knowledge, this is currently the longest distributed optical fiber sensing system without in-line repeater. The system offers potential applications in fields such as perimeter security and submarine cable monitoring.
