Aerial Fibre Optic Cable Manufacturer & Supplier
Hengtong is a China-based aerial fibre cable supplier and aerial cable manufacturer producing self-supporting overhead cable for telecom and power-line networks — ADSS, Figure-8, dual sheath, central tube and armored designs, from 12 to 288 fibers. As an OEM aerial fiber cable manufacturer with in-house fiber and stranding lines, we ship custom spans, jackets and fiber counts worldwide.
What Is Aerial Fibre Optic Cable & Who Uses It
Aerial fibre optic cable — also called overhead fibre optic cable — is installed overhead on utility poles, transmission towers and existing power-line routes, rather than in ducts or by direct burial or underground laying. Reusing existing aerial rights-of-way shortens installation time and lowers cost, and the cable holds its optical performance across a −40 °C to +70 °C working range.
Two mechanical families cover most projects. Self-supporting designs — ADSS and Figure-8 — carry their own tension across the span through aramid yarn or FRP strength members, so no separate messenger wire is needed and the cable stays fully dielectric. Non-self-supporting designs are lashed to a separate messenger on shorter distribution runs.
The cable is bought by telecom operators extending FTTH and backbone routes, by electric utilities running SCADA and grid-communication links along transmission lines, and by contractors on rural, railway and smart-city builds.

Aerial Cable Structure Types
| Structure type | Strength member | Fiber count | Jacket | Typical span | Best for |
|---|---|---|---|---|---|
| ADSS Single Jacket (all-dielectric self-supporting) | Aramid yarn / FRP | 12–144 | Single PE | 50–600 m | Power-line corridors, no earthing needed |
| ADSS Dual Sheath (double jacket) | Aramid, double jacket | up to 288 | PE inner + AT outer | Long spans | High-voltage & chemically aggressive routes |
| Mini ADSS | Twin non-metallic members | 2–24 | Single PE | 40–150 m | Last-mile FTTH on existing poles |
| Central Tube (uni-tube, armored) | FRP + parallel steel wire | up to 48 | PE / steel-tape armored | Short–medium | Compact, crush- and rodent-resistant runs |
| Figure-8 Self-Supporting | Integrated steel / dielectric messenger | 12–96 | PE | 50–300 m | Distribution networks, simple pole install |
Central uni-tube cores carry up to 48 fibers and give the smallest diameter and weight; stranded loose tube cores carry up to 288 fibers for higher-density routes. The dual-sheath build adds an anti-tracking outer jacket for high-voltage corridors, and the central-tube build can be steel-tape armored where spans are exposed to crushing or rodents.

Applications
Telecom & FTTH
Running cable through existing pole corridors avoids the permitting, excavation and surface restoration that trenching requires, and completes 3–5 times faster. That makes it the practical route over rocky terrain, farmland and protected land where digging is too costly, and for extending FTTH into rural and underserved areas.
Electric utility
Fully dielectric ADSS installs on lines energized above 500 kV without earthing or bonding, so it can share the same towers as the conductors while carrying SCADA, protection-relay and advanced metering (AMI) traffic, free of the electromagnetic interference that affects metallic cable.
5G & smart city
Overhead routes follow existing corridors to reach streetlight poles, traffic signals, cameras and sensors, which keeps 5G small-cell backhaul and municipal sensor networks straightforward to extend and to reach for maintenance.
Railway & transportation
Cable run trackside on messenger wires or catenary carries automatic and positive train control (PTC), wayside-equipment monitoring and passenger services along railway and highway corridors, unaffected by traction-power interference.
Campus & enterprise backbone
On university, hospital, industrial and multi-building sites, aerial fibre replaces distance-limited copper for inter-building backbone, adding bandwidth headroom and interference immunity, with the run finishing in days and without trenching or landscaping damage.
Rural & overseas projects
On rural electrification and cross-terrain routes the Figure-8 messenger can double as structural support and grounding, and spans, fiber counts and jackets are matched to each country's loading and voltage conditions before shipment.
Manufacturing Quality & Technical Resources
Production passes through three gates. Incoming fibers, strength members, buffer tubes, water-blocking materials and jacket compounds are inspected against material specifications; in-process controls track fiber tension, tube fill, stranding geometry and jacket concentricity in real time; and every production run is tested before shipment, with results kept as traceable QC records.
Final testing
Each run is checked for optical performance (attenuation, chromatic dispersion and PMD), mechanical performance (tensile, crush, impact and bend), environmental performance (temperature cycling, water immersion and accelerated aging), and dimensions (cable diameter, jacket thickness and length accuracy).
Datasheets, specification sheets, factory test reports and certification documents are provided for selection and project sign-off, so a build can be checked against a technical specification before it ships.
Aerial Fibre Optic Cable FAQ
Q: Which ADSS cable manufacturers are trusted for power-line applications?
A: For power-line routes, choose an aerial cable manufacturer that supplies fully dielectric ADSS with anti-tracking outer jackets rated for the line voltage, verified span and sag design, and factory test reports. Hengtong's all-dielectric ADSS installs safely near lines operating above 500 kV without earthing or electrical isolation equipment.
Q: Central tube vs stranded loose tube aerial cable — which should I choose?
A: Central (uni-tube) designs suit compact, lower-count runs up to 48 fibers, offering small diameter, low weight and good waterproofing. Stranded loose tube designs support higher fiber counts up to 288 and larger spans.
Q: What is the difference between single jacket and dual sheath ADSS cable?
A: Single jacket ADSS suits benign environments. A dual sheath (double jacket) build adds an anti-tracking outer jacket and greater protection for high-voltage corridors above 220 kV and chemically aggressive locations, supporting 25+ year service life under electrical stress.
Q: What span lengths and tensile ratings do aerial fibre optic cables support?
A: Aerial fibre optic cable spans range from 40 meters in distribution networks to over 1,800 meters across rivers, canyons and mountainous terrain, with tensile strength ratings of 8 kN to 30 kN matched to span and wind or ice loading.
Q: Which aerial cable resists rodents and fire?
A: Rodent-resistant aerial cable uses steel-tape armor or glass-reinforced jacket materials against squirrel and woodpecker damage. Fire-resistant aerial cable uses flame-retardant jacket materials for industrial, petrochemical and dense urban routes.
