Fiber optic installation materials are resistant to high temperatures

High-temperature resistant fiber optic cables use advanced coatings like (Polyimide coating properties and temperature ratings for optical fibers) 1, silicone, or high-temperature acrylates. They also employ hermetic and fused silica fibers. Optical fiber's ability to withstand extreme heat and cold directly impacts signal integrity, network reliability, and maintenance costs, especially in harsh environments like industrial facilities, outdoor installations, and data centers. This extends the potential field of application to a range from −190 °C to +385 °C. OPGW (Optical Ground Wire) integrates function of grounding with fiber communication. Standards: IEC 60794 | IEEE 1222 | RoHS. Improved fatigue resistance, high usable strength, and excellent resistance to higher temperatures. Thanks to its know-how and expertise, SEDI-ATI Fibres Optiques can offer you optical fiber-based assemblies or solutions capable of withstanding extreme temperatures of up to +800 °C, or even 1,000 °C with sapphire fiber.
