A recent study demonstrates the mechanical performance of optical fibers under harsh conditions.ANDREI STOLOV, OFSMany land and undersea oil operations rely heavily on temperature sensing for improved safety and functionality in harsh environments. Silica-based optical fibers have been increasingly used for distributed temperature and acoustic sensing applications, in which temperatures and/or acoustic signals are recorded as a continuous profile along the length of the optical fiber sensor cable. For fiber interrogation up to 15 km, well and pipeline operators can use fiber-based sensing to measure, in nearly real time, an entire wellbore or pipeline span with a resolution of 1 m or less using Raman-,...Read full articleRelated content from Photonics MediaARTICLES3D Printing Could Disrupt Status Quo of Optical Fiber FabricationResearchers at Harbin Engineering University and the University of New South Wales demonstrated the additive manufacture of silica optical fiber preforms.
