Fiber-optic distributed acoustic sensing (DAS) promises great application prospects in smart grids due to its superior capabilities, including resistance to electromagnetic interference, long-distance coverage, high sensitivity and real-time monitoring. In this paper, we review the research. Fiber-optic-based systems are useful for monitoring because they are compact, lightweight, and resistant to harsh environmental conditions. They are also resistant to electromagnetic interference and highly compatible with modern data communication systems. We offer global sales and service through a network of local offices and highly qualified partners.
