Sapphire and alumina are commonly used for ultra-high temperature applications above 1000°C. Sapphire Fabry-Perot cavity sensors, for example, are mounted at the end of an alumina tube, which separates the hot sensing zone from the optical fiber lead, providing stability and durability under prolonged high-temperature exposure . For moderately high temperatures (up to 315°C), stainless steel or aluminum sheaths are used to protect silicate glass fibers, while metal-silicone sheaths can handle temperatures up to 150°C .
