Product Description
1. Product Overview
ADSS (All-Dielectric Self-Supporting) optical fiber cable is an aerial cable specifically designed for installation along overhead power lines or telecommunication poles. It features a non-metallic structure, eliminating the need for metallic support structures or grounding. With self-supporting capability, it can bear its own weight across spans up to 1000 meters. Engineered for outdoor use in harsh weather conditions, it offers high reliability and a long service life spanning decades.

2. Cable Types
2.1 By Core Count
Core Count | Ideal Use Case | Remarks |
12 Core | Rural fiber rollout, security camera systems, low-traffic FTTH links | Low capacity, cost-effective |
24 Core | Campus networks, mid-sized ISP backbones, industrial parks | Most popular model |
48 Core | Metropolitan networks, electric utility grids, 5G backhaul | High-density transmission |
Each core contains a single optical fiber, typically of G.652D or G.657A1 type, supporting long-distance single-mode communication.
2.2 By Structure
• All-dielectric: Non-metallic construction, suitable for areas near high-voltage facilities.
• Self-supporting: Capable of covering distances between electrical towers ranging from 100m to 1000m.
• Loose tube design: Fibers are protected by gel or dry filler tubes.
• Sheath: Available in single or double layers, providing protection against UV radiation, moisture, wind, and corrosion.
• FRP Central Rod: Delivers longitudinal strength and anti-buckling performance.

4. Installation & Accessories
4.1 Installation Overview
• Direct aerial installation between poles or towers, usually without the need for additional supporting wires.
• No metallic components, thus avoiding induced voltage and eliminating the requirement for grounding.
• Easy deployment even in high-voltage environments (up to 220kV).
4.2 Common Accessories
Accessory | Purpose |
Suspension Clamp | Holds the cable on straight poles while allowing movement |
Tension Clamp | Anchors the cable at tension or termination points |
Armor Rod | Protects the cable from compression and bending at clamp points |
Vibration Damper | Reduces Aeolian vibration caused by wind |
Down Lead Clamp | Guides the cable down the pole neatly |
5. Application Scenarios
• 5G and FTTH backbone lines
• Power grid communication over 35–220kV lines
• Oil, gas, mining, or railway transmission
• Mountain or forest areas where trenching is challenging
• Campus and Enterprise Interconnection
6. Frequently Asked Questions (FAQ)
Q1: How to choose between 12, 24, and 48 cores?
A: The choice depends on the scale of the network. 12 cores are sufficient for small links, while 24 and 48 cores are suitable for medium and large backbone lines respectively.
Q2: What is the difference between PE and AT sheath?
A: PE (polyethylene) is used for low-voltage installations (≤110kV). AT sheath is made of thermosetting material, suitable for scenarios requiring resistance to electrical tracking and surges.
Q3: What is the maximum span for ADSS cable?
A: Standard spans range from 100m to 600m. Custom designs can achieve long spans of 800–1200m with enhanced tensile properties and a larger outer diameter.
Q4: Can ADSS cable be buried?
A: No, ADSS cable is specifically designed for aerial installation. For underground installation, duct cables or armored cables are recommended.
Q5: What is the lifespan of ADSS cable?
A: 25–30 years when properly installed and used in suitable environments.
