Specialty Optical Fibers For Cryogenic Applications
For applications where temperatures will be below -60°C, standard telecommunications fiber will not perform optically and a special polyimide coating is necessary. Liquid natural gas facilities and pipelines, where temperatures can drop to approximately -180°C, commonly use optical fiber for monitoring temperatures (DTS and/or DAS) to look for signs of leakage. These optical fibers are housed in fiber optic cables to allow for protection of the fiber during placement of the cable. Fibers ideal for such deployment include polyimide coated single-mode and multimode fibers and cables.
