Distributed acoustical sensing (DAS) is an advanced sensing technology that provides remote, real-time access to closely-spaced data collection sites spread across tens of kilometres of linear infrastructure -- such as pipelines, railways, and perimeters various installations. The DAS system works by converting a single optical fibre into tens of thousands of individual highly-sensitive vibrational sensors. Optical fibres yields a system immune to electromagnetic or radio frequency interface, requiring no power along the sensing length.

分布式声学传感（DAS）是一种先进的传感技术，可提供远程实时访问分布在数十公里线性基础设施（如管道，铁路和周边各种设施）上的密集数据收集站点。DAS系统的工作原理是将一根光纤转换成成千上万个独立的高灵敏度振动传感器。光纤产生了一个对电磁或射频界面免疫的系统，沿着感测长度沿着不需要功率。
