Fiber Optic Cable Routes from Africa

Africa is connected globally through multiple submarine cables and extensively linked internally via terrestrial fiber networks, forming a growing high-capacity internet backbone.

Submarine Cable Routes

Africa's international connectivity relies heavily on submarine fiber optic cables that link the continent to Europe, the Middle East, Asia, and the Americas. Key submarine cables include:

• WACS (West Africa Cable System): Runs along the west coast from South Africa to the UK, connecting multiple West African countries.
• SAT-3/WASC/SAFE: Connects South Africa to Europe via West Africa and the Indian Ocean.
• EASSy (Eastern Africa Submarine Cable System): Links East African countries to Europe and Asia.
• SEACOM: Connects South Africa, East Africa, and India.
• ACE (Africa Coast to Europe): Runs along the west coast of Africa to Europe. These cables land in major coastal cities such as Cape Town, Lagos, Accra, Mombasa, and Alexandria, providing high-capacity international bandwidth and serving as hubs for terrestrial extensions ( ).

Terrestrial Fiber Networks

Once submarine cables reach the coast, terrestrial fiber optic networks distribute connectivity inland, reaching landlocked countries and urban centers. Africa has seen rapid growth in terrestrial fiber deployment:

• By 2024, Africa had over 1.33 million route-km of operational terrestrial fiber, including 324,730 km of metropolitan and FTTH/B networks ( ).
• Major projects include Trans-Kalahari Fiber, West Africa One, and national backbones in countries like Nigeria, Ghana, Botswana, and Mauritania ( ).
• Regional networks like WIOCC integrate national backbones across multiple countries, enhancing cross-border connectivity ( ). Terrestrial networks often extend from submarine landing stations to major cities, industrial zones, and data centers, ensuring high-speed internet access beyond coastal regions.

Mapping and Visualization

Interactive maps such as TeleGeography's Submarine Cable Map ( ) and AfTerFibre ( ) provide detailed visualizations of both submarine and terrestrial fiber routes. These resources allow users to explore:

• Cable routes and landing stations
• Network ownership and operators
• Planned and under-construction projects
• Regional connectivity and capacity upgrades

Summary

Africa's fiber optic infrastructure combines international submarine cables with extensive terrestrial networks, enabling global connectivity and supporting economic growth. Continuous expansion of both submarine and terrestrial routes is increasing internet access, reducing latency, and connecting more cities and landlocked regions to high-speed networks ( ).
