Kenya Optical Cable Production Process

Kenya manufactures fiber optic cables locally through NIA Fiber, producing up to 300 kilometers per day to support national and regional connectivity.

Overview of Local Manufacturing

Kenya has recently established its first and only fiber optic cable manufacturing facility, NIA Fiber, located in Athi River, near Nairobi. This initiative is part of the government's plan to expand the national fiber optic network to 100,000 km, aiming to improve internet access and bridge the digital divide . The facility transitioned from a trading company to a full-fledged manufacturer in July 2023, marking a significant milestone in Kenya's digital infrastructure development .

Production Process

The fiber optic cable production process in Kenya follows standard international practices:

1. Preform Fabrication: High-purity silica is melted and drawn into a glass preform, which forms the core and cladding of the optical fiber.
2. Fiber Drawing: The preform is heated in a furnace and drawn into thin optical fibers, typically 125 microns in diameter.
3. Coating and Curing: The drawn fibers are coated with protective polymer layers and cured to enhance durability and flexibility.
4. Cable Assembly: Multiple fibers are bundled together, often with strength members like aramid yarn, and encased in an outer protective sheath. NIA Fiber produces customized cables, including aqua-colored variants for specific client requirements .
5. Testing and Quality Assurance: Each batch undergoes rigorous testing for attenuation, tensile strength, and environmental resilience to ensure compliance with Kenya ICT standards and international best practices .

Production Capacity and Distribution

NIA Fiber operates 24 hours a day, producing up to 300 kilometers of fiber optic cables daily. The company has already delivered over 12,000 km of cables within Kenya and exports approximately 30% of its output to countries such as Uganda, Tanzania, and Zambia . This local production reduces reliance on imports, lowers costs, and ensures faster deployment of fiber networks.

Impact on Connectivity

The local manufacturing of fiber optic cables supports Kenya's growing internet demand, with 51 million internet subscriptions, 70% of which are mobile-based . By producing high-quality, affordable cables domestically, the government aims to expand broadband access, particularly in rural areas, and facilitate digital skills training and public Wi-Fi initiatives .

Conclusion

Kenya's fiber optic cable production process combines modern manufacturing techniques, quality assurance, and customer-focused customization. The establishment of NIA Fiber not only strengthens national digital infrastructure but also positions Kenya as a regional supplier of fiber optic cables, contributing to economic growth and improved connectivity across East Africa .
