1. Project Overview
This project is a national-level communication backbone network upgrading initiative in Namibia, serving MTC (Mobile Telecommunications Company), the largest telecommunications operator in Namibia. As the leading enterprise in Namibia’s communications industry, MTC undertakes core responsibilities including the construction of national core communication networks, urban and rural communication coverage, and the provision of government and residential broadband services, acting as a core driver for local digital informatization development.
To meet the core demands of national backbone network capacity expansion, communication coverage expansion in remote areas, and upgrading of communication lines along power grids, MTC launched a large-scale optical fiber backbone network construction project. Leveraging its mature R&D and manufacturing capabilities for ADSS optical cables, rich overseas project implementation experience, and customized product solutions adapted to complex African working conditions, KEXINT successfully won the project bid. The company supplied a total of 960 kilometers of All-Dielectric Self-Supporting (ADSS) optical cables and supporting technical services, helping build a high-speed, stable and durable national-level communication transmission backbone network for Namibia.
2. Project Background & Client Pain Points
2.1 Industry & Regional Development Background
Namibia features a vast territory and complex terrain, covering diverse landforms such as deserts, gobi, hills and high-voltage power transmission corridors. For a long time, the region has suffered from insufficient coverage of communication backbone lines, limited bandwidth capacity and poor network stability. With the development of the local digital economy, growing demand for residential broadband, and the popularization of government and enterprise digital services, outdated traditional communication lines can no longer support high-speed data transmission and long-distance signal coverage. Frequent network congestion and signal interruptions have severely restricted the upgrading of local informatization construction and people’s livelihood communication services.
2.2 Core Client Pain Points
Poor Adaptability to Complex Working Conditions: Most project routes are laid along high-voltage power corridors and open desert areas. Traditional optical cables are vulnerable to electromagnetic interference from high-voltage electric fields, wind-sand erosion and extreme temperature differences, resulting in signal attenuation, line aging and frequent faults. This imposes extremely high requirements on the insulation, weather resistance and anti-interference performance of optical cables.
High Cost of Long-Distance Laying: Most areas in Namibia are sparsely populated with long intervals between communication stations. Ordinary optical cables have insufficient spanning capacity and require frequent erection of support towers, which greatly increases construction costs, prolongs the construction period and raises subsequent operation and maintenance difficulties.
Strict Quality Standards for Overseas Projects: As a national backbone network project, it has stringent requirements for the transmission stability, service life and compliance of optical cables. Products must comply with multiple international certifications including CE, RoHS and ISO9001. Meanwhile, suppliers are required to have capabilities of mass delivery, timely supply and localized overseas technical services.
Urgent Demand for Full-Network Capacity Expansion: The bandwidth of the original network was saturated, failing to support the implementation of new services such as 5G extended coverage, fiber-to-the-home (FTTH) and government-enterprise dedicated lines. High-capacity and high-stability backbone optical cables were in urgent need to complete full-network upgrading and capacity expansion.
