Construction of fiber optic cables in Africa

Africa has been rapidly expanding its terrestrial fiber optic networks, with over 1.3 million kilometers deployed by 2024, connecting urban centers, landlocked countries, and regional hubs.

Overview of Fiber Optic Infrastructure

Terrestrial fiber optic cables in Africa are land-based networks that extend connectivity from submarine cable landing stations to inland cities, rural areas, and cross-border corridors, forming high-capacity backbones for telecommunications and internet services . Unlike submarine cables, which primarily link continents, terrestrial networks ensure intra-continental connectivity, reduce latency, and provide redundancy for national and regional data traffic . These networks are essential for digital economies, e-governance, mobile backhaul, and broadband expansion.

Key Projects and Regional Initiatives

• East and Southern Africa: Angola Telecom and Liquid Dataport activated a new fiber route from Luanda to Johannesburg, passing through the Democratic Republic of the Congo, Zambia, and Zimbabwe, enhancing regional backbone diversity . A 2,500 km direct link from Luanda to Lusaka via Chavuma was also operationalized in 2023 to strengthen COMESA connectivity .
• Central and Southern Africa: A 10,000 km regional fiber-optic backbone is under construction across the Democratic Republic of Congo, Zambia, Zimbabwe, Malawi, and Mozambique, targeting around 90 million people and connecting 3,000 schools, 1,500 hospitals, and 1,200 government institutions .
• National Backbones: Countries like Kenya (NOFBI) and South Africa have developed extensive national fiber networks, while transnational projects like the Trans-Saharan Optic Fibre Broadband Project span over 4,500 km using dense wavelength division multiplexing technology .
• West Africa: Initiatives such as the EurAfrica Gateway Cable aim to extend broadband coverage to communities in countries including the Democratic Republic of Congo, Mali, Mozambique, Tanzania, Uganda, Zimbabwe, Zambia, and Madagascar, bridging the digital divide and fostering EU-Africa cooperation .

Impact and Challenges

The expansion of terrestrial fiber networks has tripled capacity since 2010, significantly improving broadband penetration and economic integration . However, challenges remain:

• Uneven rural access: Nearly 300 million people live more than 50 km from fiber networks .
• Maintenance and redundancy: Incomplete builds or single-path dependencies can create connectivity gaps .
• Funding and partnerships: Many projects rely on public-private partnerships, multilateral funding, and international loans, such as the Exim Bank of China supporting Malian fiber projects .

Conclusion

The construction of fiber optic cables in Africa is a strategic driver of digital transformation, connecting urban and rural areas, supporting education, healthcare, and government services, and enabling regional economic integration. Ongoing projects across Central, Southern, and West Africa demonstrate a commitment to bridging the digital divide and building resilient, high-capacity networks for the continent.
