Application of Distributed Fiber-optic Sensing for Pipeline Integrity and Security

By Dr. Alasdair Murray, Senior Analyst, Dominic Graham, Specialist Engineer, and Dr. Chris Minto, Engineering Director, OptaSense  Distributed fiber-optic sensing (DFOS) describes several technologies that can be utilized to convert a fiber-optic cable into an array of distributed sensors by connecting it to an optical interrogator unit (IU). Fundamentally, the technology relies on launching laser light along the fiber-optic cable and detecting light that is scattered back along the fiber.  Figure 1 As light propagates through the fiber, it interacts with microscopic inhomogeneities in the glass. These interactions result in a small f
