FTTH Fireproof Optical Fiber Cable

FTTH fireproof optical fiber cable is a specialized last-mile communication cable designed for fiber-to-the-home network deployment, focusing on fire safety, stable signal transmission and indoor environmental adaptability. Different from ordinary optical cables, this cable adopts high-performance low-smoke zero-halogen (LSZH) flame-retardant sheath materials as the core protective structure, which complies with international fire safety standards for building wiring. It is specially developed for indoor access scenarios such as residential buildings, commercial office buildings and indoor corridor wiring, solving the safety hazards of traditional optical cables that are easy to burn, release toxic halogen gas and produce dense smoke in case of fire. The cable features a compact and flexible structure with high bending resistance, adapting to complex indoor wiring environments such as wall wiring, ceiling laying and corner bending, ensuring convenient and efficient on-site construction.

In terms of structural design, FTTH fireproof optical fiber cable is equipped with high-strength FRP reinforcement components, which effectively resist tensile pressure and external extrusion during installation and long-term use, avoiding fiber core damage and signal attenuation. The internal optical fiber core adopts high-purity glass fiber with ultra-low loss transmission performance, which can stably carry high-bandwidth services such as gigabit broadband, 4K/8K video transmission and smart home data transmission. Its unique fire-resistant and self-extinguishing performance can prevent flame spreading along the cable laying path in fire accidents, greatly reducing the risk of fire escalation. Meanwhile, the low-smoke and non-toxic characteristics ensure clear evacuation vision and avoid toxic gas poisoning, providing reliable safety guarantee for personnel and property in building fire scenarios.

In practical application, this fireproof FTTH cable has excellent environmental adaptability, maintaining stable working performance in the temperature range of -20℃ to 80℃, and resisting aging and corrosion caused by long-term indoor humidity and air oxidation. It has passed multiple professional fire resistance tests and building wiring safety certifications, and is widely used in national smart community construction, commercial building communication transformation and indoor terminal access engineering. With the rapid popularization of smart home and high-speed fiber access, FTTH fireproof optical fiber cable has become an indispensable core component of safe and reliable home fiber-optic access networks, balancing high-efficiency communication transmission and building fire safety.
