Figure-8 fiber optic cables are self-supporting, low-loss aerial cables designed for rugged field deployment, offering easy installation, water-blocking, and stable optical performance.

Key Features

Self-Supporting Design: Figure-8 cables integrate a messenger wire or stranded steel core, allowing spans of hundreds of meters without additional support hardware, reducing installation time and cost . Low-Loss Optical Performance: These cables use loose tube construction to isolate fibers from mechanical stress, maintaining low attenuation across a wide temperature range. They are compatible with single-mode (OS1, OS2, G.652, G.657) and multi-mode fibers (OM2, OM3, OM4), ensuring minimal signal loss for long-distance communication . Water-Blocking and Durability: Gel-free or water-swellable materials prevent water ingress while simplifying mid-span access and maintenance. The medium-density polyethylene (PE) jacket provides rugged protection against environmental exposure, UV, and abrasion . Mechanical Strength: The figure-8 structure with steel or dielectric messenger wire provides high tensile strength, crush resistance, and flexibility, making it suitable for aerial deployment on poles or towers . Field-Friendly Installation: Flexible buffer tubes and SZ-stranded loose tube design allow easy routing in closures and splicing, while the figure-8 shape enables one-step installation using standard hardware .

Applications

• Rural broadband and FTTH deployments
• 5G small cell backhaul
• Utility co-deployment projects
• Long-span aerial installations without intermediate supports

Considerations for Field Operations

• Fiber Type Selection: Single-mode fibers are preferred for long-distance, low-loss applications, while multi-mode fibers are suitable for shorter spans.
• Environmental Conditions: Choose gel-free or water-blocked designs for wet or humid environments.
• Tensile and Span Requirements: Verify the cable's rated tensile strength and maximum span to ensure safe aerial deployment.
• Installation Hardware: Standard aerial hardware can be used, but ensure compatibility with messenger wire diameter and pole spacing.
