Distributed acoustic sensing (DAS)…results demonstrate that φ-OTDR can be used to quantitatively measure strain in roads associated with events as small as a dog walking on the surface.
Fotech’s innovative DAS technology essentially turns a fiber optic cable into thousands of sensors....technology provides valuable information for various applications in pipeline integrity, security, power infrastructure and telecommunications
Most railway tracks already utilize pre-existing, trackside fiber optic cable infrastructure, which makes fiber optic train and rail monitoring incredibly advantageous.
potential of transforming long-haul fiber optic transmission cables into sensing cables….would enable submarine cable owners, and operators, to explore previously unexplored parts of the ocean and even predict geophysical events
For smart cities, this is where fiber optic technology is key. Data - and the sensors and technology used to collect it - is central to smart city development....The right technology is already here….fiber optic telecommunication cables can be used as sensors; Distributed Acoustic Sensing (DAS)
