Figure 8 Uni-Tube Non-Armored Self-Supporting Aerial Cable

This fiber optic cable uses a figure-8 construction where two fiber groups are arranged symmetrically around a central steel messenger wire. It is non-armored, making it lightweight and easy to install, while still offering durability and reliable optical performance. Designed for overhead installations, it is perfect for outdoor telecom and broadband networks, where it provides cost-effective and efficient data transmission.

1. Structure & Design

• Figure 8 Construction: Two fiber optic groups are arranged in a figure-8 configuration around a central steel messenger wire, making the cable self-supporting.
• Uni-Tube Design: The optical fibers are housed within a single protective tube for increased fiber protection and easy handling.
• Water-Blocking Gel: Protects the fibers from moisture and ensures long-term reliability in various environmental conditions.
• UV-Resistant PE Sheath: Provides added protection against UV radiation and weather exposure, enhancing outdoor durability.
• Lightweight & Compact: The non-armored design reduces the overall weight, simplifying installation and handling.

2. Applications

• Aerial installations for telecommunications and broadband networks.
• Suitable for long-distance and backbone fiber optic networks.
• Ideal for rural and urban areas requiring efficient, self-supporting cable systems.
• Perfect for overhead fiber optic connections with minimal environmental exposure.

3. Advantages

• Self-Supporting Design: Eliminates the need for additional messenger wire, reducing installation time and costs.
• Lightweight & Easy to Install: The non-armored structure makes the cable easier to handle, install, and maintain.
• Durable Outdoor Performance: UV-resistant PE sheath ensures the cable performs reliably in harsh weather and outdoor environments.
• Water-Resistant: Moisture protection ensures the fiber maintains high-performance standards, even in wet conditions.
• Cost-Effective: The non-armored design keeps costs low while still offering reliable performance for long-distance data transmission.

4. FAQs

• Can this cable be used in areas with extreme weather?
