ADSS optical cable parameters and models

ADSS (All-Dielectric Self-Supporting) optical cables are non-metallic, self-supporting aerial fiber cables designed for installation along or near power lines, available in single or double sheath designs with fiber counts from 12 to 432.

Overview

ADSS cables are all-dielectric, meaning they contain no metallic components, allowing installation near high-voltage lines without electromagnetic interference. They are suitable for aerial transmission and distribution, supporting live-line installation and harsh environmental conditions .

Key Models and Variants

1. Single Sheath (ADSS-SS)
   • Designed for shorter spans (typically 80–150 m)
   • Economical and lightweight
   • Suitable for medium-voltage (MV) lines
   • Loose tube design with gel or dry water-blocking elements
   • Fiber counts: up to 144 fibers
2. Double Sheath (ADSS-DS)
   • Designed for longer spans (200–400 m)
   • High-strength construction for high-voltage (HV) lines
   • Outer sheath options: standard PE or anti-tracking (AT) for high-voltage environments
   • Fiber counts: up to 432 fibers
3. FlexTube® Micromodule Cables
   • Thin-wall flexible tubing housing single-mode fibers
   • Water-tight dry core with aramid yarn and GRP strength members
   • Optimized for aerial installation or duct blowing/pulling
4. Corning ADSS Aramid Single Jacket
   • Short-span, self-supporting design for campus or telecom backbones
   • Loose tube with SZ-stranding for mid-span access
   • Span: up to 100 m in light/medium NESC conditions, 50 m in heavy conditions
   • HDPE jacket, water-blocking materials, ITU-T G.652D compliant fibers

Typical Specifications

Features and Advantages

• Self-supporting: No metallic messenger wire required
• High voltage tolerance: Track-resistant jackets for up to 25 kV space potential
• Durable: Resistant to UV, weather, and mechanical stress
• Flexible fiber access: SZ-stranded or micromodule designs allow mid-span access
• Customizable: Fiber count, sheath type, and span length can be tailored to project requirements

Applications

• Electric utility transmission and distribution lines
• Medium and high-voltage aerial installations
• Telecommunications backbones and campus networks
• Environments requiring live-line installation or high mechanical strength ADSS optical cables provide a reliable, long-life solution for aerial fiber deployment, combining mechanical strength, environmental resistance, and flexibility in fiber count and span length. For specific project requirements, manufacturers like AFL, Zion, Prysmian, and Corning offer detailed ordering guides and custom configurations.
