Transport Security World interview with FOSA Chairman JJ Williams: Fiber optic sensing technology converts cables installed alongside transport infrastructure, such as railroads or highways, into an array of thousands of sensors which can detect acoustics, temperature or strain signals by using optical sensing techniques. Using signal pattern recognition of this acoustic, temperature or strain data, fiber optic sensing systems can infer what is happening along an asset, with a near instantaneous response that gives high location accuracy. What this means is that infrastructure operators can get warnings of potential incidents, with a high accuracy of where these problems occur that leads to reduced operating risk, cost and increased infrastructure life and efficiency....Each fiber optic sensing system can typically monitor many kilometers of asset, which means it is a cost-effective sensor over long distance. Most systems can also use fiber optic cables that are already in place alongside assets as the sensor.
