Namibia primarily uses imported single-mode fiber cables, with G.652.D and G.657.A2 as standard models for backbone, feeder, and drop applications.

Standard Optical Cable Types in Namibia

Namibia does not manufacture optical cables locally; all fiber, closures, and splice trays are imported. The standard models are categorized based on their deployment:

• G.652.D Loose-Tube Duct and Direct-Buried Cable: Used for backbone and feeder networks, providing low attenuation and high reliability over long distances, suitable for Telecom Namibia's FTTx and national backbone projects .
• G.657.A2 Bend-Insensitive Drop Cable: Designed for the last stretch into premises (FTTx), allowing tight bends without signal loss, ideal for urban and residential installations .
• ADSS (All-Dielectric Self-Supporting) Cable: Used for aerial routes over long inter-town spans, especially where laying duct is uneconomical. ADSS cables are metallic-free, reducing interference and suitable for high-wind, ice-free conditions .

Deployment Context

• Telecom Namibia: The largest single fiber buyer, deploying G.652.D and G.657.A2 across Windhoek, Swakopmund, Walvis Bay, and other towns for FTTx and backbone networks .
• Paratus Namibia: Focuses on private and carrier-neutral networks, including the 1,890 km Trans-Kalahari Fibre route, procuring duct, ADSS, and high-fiber-count backbone cables .
• NamPower and Mobile Operators: Use OPGW and other specialized cables for utility and mobile backhaul networks .

Suppliers and Access

Key suppliers and distributors in Namibia include:

• Swanib Cables: Offers fiber optic cabling products for telecom and industrial applications .
• Cable Feeder Systems Namibia (CFS): Supplies fiber optic cables and accessories for high-speed data transmission, including structured copper and fiber systems .
• Taitron and other AV suppliers: Provide optical input cables for broadcast, enterprise, and industrial AV applications .

Summary

The Namibian standard optical cable model relies on imported single-mode fibers, primarily G.652.D for backbone/feeder and G.657.A2 for drop connections, with ADSS cables for aerial deployment. These standards ensure reliable, high-speed connectivity across urban, industrial, and inter-town networks, supporting both public and private sector infrastructure projects .
