Columbia Anti-Trace Optical Cable 8 Cores

The 8-core Columbia Anti-Trace Optical Cable is a durable, high-performance fiber optic cable designed for outdoor and indoor applications, featuring armored protection, water-blocking, and support for both singlemode and multimode fibers.

Cable Construction and Features

The cable typically consists of 8 optical fibers housed in a central loose tube, which is filled with a water-resistant jelly to prevent moisture ingress and protect the fibers from environmental damage . For outdoor applications, the cable may include double steel wire strength members and corrugated steel tape armoring, providing high tensile strength and resistance to mechanical stress, making it suitable for direct burial, duct, and aerial installations . The outer jacket is usually made of UV-resistant, low-smoke, halogen-free material, ensuring safety and environmental compatibility .

Fiber Types and Performance

The cable supports both singlemode fibers (G.652D) and bend-insensitive fibers (G.657A1), allowing flexibility for long-distance backbone networks or access networks . For indoor breakout versions, OM3 or OM4 multimode fibers are used, providing high-speed data transmission with low attenuation and excellent performance in LAN or data center environments .

Mechanical and Installation Specifications

• Tensile Strength: High, due to steel wire reinforcement, suitable for aerial suspension between poles .
• Minimum Bending Radius: 20× outer diameter during installation (dynamic) and 10× outer diameter when static .
• Pulling Force: Designed to withstand significant pulling during installation without fiber damage .
• Environmental Protection: Water-blocking compounds and armored construction protect against moisture, rodents, and mechanical impact .

Applications

The 8-core optical cable is ideal for:

• Telecommunication backbone networks
• Access networks and campus networks
• Indoor data centers and office buildings (for breakout OM3/OM4 versions)
• Outdoor aerial, duct, or direct burial installations requiring robust protection and long-term reliability .

Summary

The Columbia Anti-Trace 8-core optical cable combines mechanical durability, environmental protection, and high-performance fiber transmission, making it suitable for both indoor and outdoor network deployments. Its armored and water-blocking design ensures stable long-distance transmission, while the choice of singlemode or multimode fibers allows flexibility for various network requirements .
