Standard cables often max out around 85°C to 125°C. However, high-temperature specialized fibers 2, employing polyimide or other advanced coatings, can endure continuous operation at 300°C and even survive short-term exposures near 490°C. As a trusted provider of optical communication solutions. The developments introduced in the optical communication systems have been focused in 3 main objectives: increase of the propagation distance, increase of the transmission capacity (bitrate) and reduction of the deployment and operation costs. The achievement of these objectives was only possible. Fiber optic cables are designed with different material thresholds. The cable is suitable for both indoor and ou door installation. The outer sheath is made from black UV-stabilized and weather resistant material which is SHF1 classified, and may be exposed for shorter periods to fluids such as diese and mineral oils. If it is an optical fiber cable used in industry, each fiber cable has a different composition, the high temperature and low temperature it can withstand. The temperature limit for fiber optic cable typically ranges from -40°C to 70°C, although some cables may have a wider temperature range depending on their design and intended use.
