As part of South Africa's Digital Infrastructure Plan 2025, several municipalities—including Johannesburg, Cape Town, and eThekwini (Durban)—launched programs to deploy high-speed fiber-optic broadband across public infrastructure. These deployments were aimed at supporting e-government services, surveillance, education, and connectivity for underserved communities.
In 2023, Uni-Cable successfully exported a complete All-Dielectric Self-Supporting (ADSS) Cable system including fiber cable and all required accessories to a local contractor working on a government-funded smart city initiative in KwaZulu-Natal Province.
End-to-end solution: fiber + tension hardware + suspension accessories
Custom cable design for 70m span length with high wind resistance
Fully type-tested to IEC 60794-4-20, ISO/IEC 11801, and Telcordia GR-20
Direct-from-factory pricing with fast production and containerized export

Special Design Feature:
Uni-Cable supplied a customized double-layer sheath for improved abrasion and UV protection—ideal for long-term aerial installation in harsh outdoor environments.
| Accessory | Description |
|---|---|
| Suspension Clamp | For mid-span support with elastomer insert for vibration damping |
| Tension Clamp (Dead-End) | Preformed rods with outer armor grip to protect cable under strain |
| Thimble & Anchor Shackles | For pole anchoring |
| Downlead Clamp | Fixes cable to pole or wall between suspension point and entry |
| Splice Closure | Aerial/mast-mount, IP68 rated, 48–144 core capacity |
| Pole Brackets | Hot-dip galvanized for harsh coastal/mountain zones |
All accessories were matched precisely to cable diameter and span design. CAD drawings and pole layout guides were provided with the shipment.
Cable testing per IEC 60794 and GR-20:
Attenuation ≤ 0.36 dB/km (1310 nm)
Crush, tensile, impact, and bend tests
Temperature cycling and water penetration
Hardware testing:
Tensile tests (ASTM B117)
Galvanization thickness check (≥ 85µm)
Salt spray for 1000 hours (coastal zone compliance)
Inspections were witnessed by SGS South Africa at port and by the local EPC firm’s fiber QA engineer.
Fiber cables on 2,000m non-returnable wooden drums with internal core locks
Accessories bagged per span section and boxed per pole kit
Custom labels in English and Afrikaans
Shipment in 1x20GP container, FOB Shanghai, delivery to Durban Port
Documentation included:
Factory Test Report (FTR)
Certificate of Origin
Bill of Lading, Packing List
Project-specific QA Certificate
By early 2024, over 120 km of aerial fiber cable had been installed across municipal roads and township zones, with successful integration into the local data exchange node.
The use of Uni-Cable’s ADSS + hardware bundle cut installation time by 20%, and the tool-free preformed tension clamps allowed non-specialist teams to complete mounting without needing hydraulic tools.
Factory-direct = 25% cost savings vs. prior European brands
