Fire-resistant Optical Fiber Cable

Fire-resistant optical fiber cable is a special type of communication cable optimized and upgraded in terms of fire safety performance on the basis of ordinary optical fiber cables, which is dedicated to high-fire-risk and high-safety-level communication wiring scenarios. Different from ordinary optical cables that are easy to burn and spread flame in case of fire, this cable adopts professional fire-resistant structural design and high-performance flame-retardant materials, with excellent fire resistance, flame retardancy, and smoke suppression performance. It can maintain normal communication transmission for a certain period of time in high-temperature and fire environments, and effectively prevent flame spread, providing key safety guarantees for emergency communication in fire accidents.

In terms of structural and material design, the fire-resistant optical fiber cable adopts a layered protection structure. The inner core uses high-purity optical fiber glass core to ensure stable optical signal transmission without attenuation. The middle layer is filled with high-temperature resistant and flame-retardant reinforcing materials, which can resist high-temperature baking and isolate flame conduction. The outer sheath is made of low-smoke halogen-free flame-retardant polymer materials, which will not produce toxic and harmful smoke when burned, avoiding secondary pollution and personnel injury. At the same time, the cable has good tensile, compression and bending resistance, adapting to complex wiring environments such as pipeline laying, overhead laying and wall wiring.

The most core performance advantage of fire-resistant optical fiber cable is its fire emergency communication guarantee capability. In the event of building fire, it can delay cable burnout, maintain the continuity of fire alarm system, emergency communication system, monitoring system and network signal transmission, and provide valuable time for personnel evacuation and fire rescue. In addition, it has the characteristics of low smoke, zero halogen, environmental protection and aging resistance, meeting national fire protection safety standards and industrial environmental protection requirements. It is widely used in high-standard fire protection scenarios such as high-rise buildings, shopping malls, subway tunnels, power stations, chemical plants, and government and enterprise key computer rooms, and is an indispensable safety communication material in modern building intelligent wiring and emergency guarantee systems.
