Distributed acoustic sensing (DAS) can turn every meter of a fiber optics cable into a vibration or strain sensor....real-world use cases describe the technical reality of tracking vibration along a fiber optic cable,
DAS can detect vibrations caused by water being forced through a pipeline rupture, or by ground displacement associated with small leaks in pipelines that would otherwise remain undetected
Staffordshire County Council is working with Fotech to improve air quality through the use of fiber optic sensing technology. Fiber optic sensing technology is a unique way of detecting vehicle movements using standard telecom fibers that run next to the roadside.
The smart city movement has grown in the last 10 years as a direct result of the world’s increasing urbanization. Indeed, by 2050 more than two-thirds of the earth's population will live in urban areas.
Fiber optic based technology can provide cities with real-time positional insights about their road and public transport infrastructure....DAS is a photonic sensing technology that essentially ‘plugs in’ to existing fiber optic cable networks and transforms them into sophisticated acoustic sensors.
