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)
OptaSense and the British Geological Survey (BGS) have been using an OptaSense fiber-optic Distributed Rayleigh Sensing system to monitor strain changes on a slope that forms part of the BGS National Landslide Laboratory
fire…disrupted Westbahn services for more than 7 hours….Distributed Temperature Sensing is a cost effective alternative to conducting manual cable measurements, providing real-time temperature information and monitoring
researchers at NEC have shown it is possible to monitor traffic using “lit” fiber after separating out sensor and telecom data. Giovanni Milione of NEC Laboratories America, and colleagues used such fiber in Dallas and New Jersey to record the speed of cars as accurately as can be done with cameras
OptaSense having instrumented more than 25,000 km of pipes-including the 1850 km of the Trans-Anatolian Natural Gas Pipeline running across Turkey.
