Inquiry about 24-core figure-eight optical fiber cable

A 24-core figure-eight optical fiber cable is a self-supporting outdoor cable designed for aerial installation, offering high tensile strength, water resistance, and versatile fiber options.

Structure and Design

The 24-core figure-eight cable features a unique figure-8 profile, where a steel stranded wire serves as the self-supporting member, providing robust tensile strength for aerial deployment and installation ( ). The fibers, either single-mode (G.652D, G.657A1/A2) or multimode (OM1–OM4), are housed in loose tubes made of high-modulus plastic, which are stranded around a metallic central strength member. Water-blocking materials are distributed within the interstices, and a PE sheath completes the figure-8 structure, ensuring environmental protection ( ).

Mechanical and Environmental Performance

• Tensile Strength: Can withstand short-term pulling forces up to 5000N, ensuring durability during installation ( ).
• Crush and Impact Resistance: Corrugated steel tape armor and PE outer sheath provide protection against crushing and mechanical impacts, including gunshot resistance ( ).
• Temperature Range: Operates reliably from -40°C to +70°C, suitable for diverse climates ( ).
• Waterproofing: Incorporates a water-blocking system and loose tube filling compounds to prevent moisture ingress ( ).

Applications

This cable is primarily used for self-supporting aerial installations in outdoor environments. Its compact diameter and lightweight design simplify installation, while the figure-8 structure allows it to be mounted directly on poles without additional support ( ). It is suitable for long-distance inter-office communications, FTTH/FTTX networks, and broadband access systems.

Additional Features

• Low Dispersion and Attenuation: Ensures high-quality signal transmission over long distances ( ).
• Flexible Core Options: While this model has 24 cores, figure-8 cables are available with 4 to 96 cores, allowing network customization ( ).
• Durability and Warranty: Many manufacturers offer 25-year warranties, reflecting long-term reliability ( ).
• Customization: OEM/ODM services are available for fiber brand, sheath color, and logo ( ). In summary, the 24-core figure-eight optical fiber cable is a robust, versatile solution for outdoor aerial fiber networks, combining mechanical strength, environmental protection, and flexible fiber configurations to meet modern communication infrastructure requirements.
