Lianhe Guangzi has successfully initiated the group standard titled “Performance Testing Methods for Fiber-Optic Distributed Acoustic Sensing (DAS).”

On October 20, 2025, the Standardization Committee of the Chinese Society of Optical Engineering organized a feasibility study meeting for the development of the standard "Performance Testing Methods for Fiber-Optic Distributed Acoustic Sensing (DAS)."

DAS dam leakage monitoring and detection technology and equipment have been designated for key promotion by the Ministry of Water Resources.

As a technological achievement that combines both innovation and practicality, this system—centered on distributed acoustic sensing (DAS) technology—has established a comprehensive, dynamic monitoring network for dams, overcoming the limitations of traditional monitoring methods, which were characterized by non-real-time and discrete data collection. It has enabled a transformative upgrade toward high-density, real-time, and intelligent monitoring, providing an innovative solution for dam safety protection.
