Maximum temperature for advanced fiber optic cables can exceed 300°C continuously. These figures far surpass standard telecom-grade fibers. Improved fatigue resistance, high usable strength, and excellent resistance to higher temperatures. DrakaElite High temperature resistant fibers DrakaElite's High Temperature Resistant Fibers provide optimum. High temperature cables (also known as High Temp cables) represent a vast range of cables which continue to perform at increased and elevated temperatures. We supply a range of high temperature cables that are manufactured in accordance with various British and International Standards, including. Harsh environment optical fibers are designed for use at elevated temperatures and pressures in aggressive chemical environments. Typical applications include the oil & gas and geothermal industries, where the fibers are used for real-time downhole temperature and pressure measurements, data.
