Abstract
This IDC Market Note investigates the status of fiber-optic sensing as it relates to public and private infrastructure monitoring. Fiber-optic sensors can be deployed to monitor bridges, tunnels, road maps, and railways for strain and increased vibrations and indicate an imminent failure. Similarly, pipelines that carry oil, gas, and water can benefit from early leak detection and temperature variation detection. The use of fiber-optic sensing technology for the monitoring and diagnosis of the condition and performance of pipelines could provide a sound engineering and economic basis for the major decisions that will have to be made concerning the operation, maintenance, refurbishment or replacement, and life extension of these items. The savings made by avoiding or delaying refurbishment or replacement can be substantial.
Further, the high resolution, insensitivity to electromagnetic interference, real-time monitoring capabilities, and relatively low cost of fiber sensors are characteristics expected to improve pipeline safety and operation and provide great potential benefit to the industry and society as a whole. Communications systems using optical fibers have several attractive features and advantages over conventional communications means, and their performance has been proven over the past two decades. The value offered by these systems has now been augmented by the ability to simultaneously monitor, in real time, the integrity of the cable, as well as any structure or material near the cable or to which the cable is attached.
