Flame-retardant composite optical cables combine fiber optics and power conductors in a single LSZH jacket, ensuring high-speed data transmission and fire safety for smart building applications.

Overview

Flame-retardant composite optical cables are designed for indoor installations in smart buildings, supporting both data transmission and remote powering of devices such as distributed antenna systems, small cells, and building automation systems. These cables typically integrate single-mode or multimode fiber with stranded copper conductors under a single jacket, providing a hybrid solution that reduces installation complexity while maintaining safety and performance standards (Corning ActiFi®) .

Key Features

• Fire Safety Compliance: Cables are manufactured with Low Smoke Zero Halogen (LSZH) materials and meet international fire standards such as IEC 60332-2-3, IEC 60331, CPR B2ca, and FE180, ensuring minimal smoke, zero halogen emissions, and circuit integrity during fire events .
• Hybrid Design: Combines fiber for high-speed data and copper for remote powering, allowing simultaneous communication and power delivery in one cable .
• Mechanical Durability: Many designs include non-metallic FRP strength members, corrugated steel tape armor, or gel-free dielectric construction to resist bending, impact, and environmental stress .
• High-Density and Flexible Deployment: Ribbon or loose-tube constructions support high fiber counts (up to 3456F), suitable for backbone networks, data centers, and campus installations. Flexible buffer tubes and bend-insensitive fibers allow installation in tight spaces, ducts, or vertical shafts .

Applications in Smart Buildings

• Distributed Antenna Systems (DAS) and small cell networks for enhanced indoor wireless coverage.
• Building automation and IoT devices, including sensors, alarms, and control systems.
• Critical communication systems in public buildings, hospitals, airports, and tunnels where fire-resistant operation is essential .
• Data center interconnects and campus backbone networks requiring high-capacity, fire-safe fiber deployment .

Advantages

• Continuous Operation During Fire: Maintains optical signal integrity and power delivery even under extreme heat, supporting emergency systems and evacuation protocols .
• Future-Proofing: High-speed fiber supports growing bandwidth demands and long-distance transmission without signal loss .
• Safety and Compliance: LSZH and CPR-rated materials reduce toxic smoke and flame propagation, enhancing occupant safety and meeting EU and international building codes .

Conclusion

For smart building projects, standard flame-retardant composite optical cables like Corning ActiFi®, Draka FireTuf, ETK Kablo B2ca, and ScaleFibre SmartRIBBON™ provide a reliable, fire-safe, and high-performance solution. They combine data and power delivery, comply with strict fire safety standards, and are suitable for critical infrastructure, high-density networks, and emergency systems, making them ideal for modern intelligent building environments.
