Meta’s 2Africa Cable Boosts Africa’s Digital Connectivity

The Meta-led consortium behind the 2Africa project has completed the core infrastructure of the world’s longest subsea cable, a 45,000km open-access system that encircles the African continent. Partners, including MTN’s Bayobab, Vodafone Group, and WIOCC Group, finalized this monumental phase, marking a significant leap toward expanding digital access for over three billion people across 33 countries.

What the 2Africa Cable Project Means for Global Connectivity

The 2Africa system establishes a continuous undersea link between Africa, Europe, and Asia, the first cable to connect East and West Africa as a unified network. What can be describes as a continental digital superhighway, the project positions Africa as a critical hub in global data flows.

When complete, including the “Pearls” extension in 2026, 2Africa will surpass 45,000km, longer than the Earth’s circumference. This open-access design is expected to foster competition among service providers, reduce bandwidth costs, and enable faster, more reliable connectivity from coastal regions to landlocked countries.

Engineering the World’s Longest Subsea Cable

The 2Africa system introduces several industry-first technologies to maximize capacity and resilience. It utilizes advanced spatial division multiplexing (SDM) with up to 16 fibre pairs, which is twice the capacity of earlier systems, and integrates undersea optical wavelength switching for dynamic traffic management.

*The 2Africa Subsea Cable reaches 3 continents and lands in 33 countries, connecting over 3 billion people.*

This architecture is designed to handle growing demands from AI workloads, cloud services, and data center interconnections. Engineers also improved physical resilience by increasing burial depth by 50% and rerouting cables around high-risk seabed regions, such as the Congo Canyon.

Powering Africa’s Digital Economy

The West African segment alone delivers up to 180 Tbit/s of total capacity, enough to stream over 36 million HD movies simultaneously. For key cities such as Lagos, Nairobi, and Cape Town, this capacity expansion could eliminate internet congestion, significantly improving speeds for businesses, households, and schools.

Lower wholesale costs will allow ISPs and mobile network operators to provide more affordable data packages, strengthening local digital ecosystems.

Economic Growth and Market Expansion

Meta projects that 2Africa could add up to US$36.9 billion to Africa’s GDP within its first few years of full operation. Evidence from earlier subsea cable landings supports this outlook, with measurable boosts in job creation, productivity, and local tech innovation.

By enabling direct, low-latency connectivity, the cable supports a new wave of investments in data centers, 5G infrastructure, and cloud computing platforms, helping Africa bridge its digital divide.

Strengthening Africa’s Digital Sovereignty

Beyond capacity gains, 2Africa enhances Africa’s digital autonomy by introducing new, direct routes that complement existing connections through Europe and the Middle East, giving African nations greater access over data pathways and resilience in global traffic routing.

With African partners like Bayobab (MTN Group) and WIOCC in the consortium, 2Africa represents a model of regional collaboration in building critical infrastructure for the future digital economy.

What’s Next for 2Africa

The project’s final milestone, the Pearls extension, will extend connectivity to the Arabian Gulf, India, and Pakistan by 2026. Once operational, the cable will serve as a foundational layer for Africa’s next-generation digital services, including AI, fintech, and blockchain-based applications.

As an open-access system, the consortium will continue onboarding regional operators, ensuring equitable participation in Africa’s rapidly expanding internet ecosystem.
