Beyond the Signal: Why Africa’s Next Telecom Era Will Be Built Beneath the Surface
June 24th 2026
For most of the past two decades, investment in African telecommunications has been concentrated at the network edge. These investments delivered measurable returns, but the architectural constraint binding the continent’s next phase of digital growth sits deeper below the surface, specifically, in the subsea cable systems that determine how much capacity enters the continent, at what cost, and through whose infrastructure.
For Africa, submarine cables are the primary determinant of wholesale bandwidth pricing, network resilience, and by extension, the commercial viability of every downstream service built on top of them.
Notably, capital deployment into African subsea infrastructure is accelerating and the ownership profile of that infrastructure is shifting from traditional telecom consortia toward hyperscale technology companies.
Africa currently has 77 active or planned subsea cable systems as of 2025, yet more than half of the continent’s international bandwidth remains concentrated in just five countries: Nigeria, South Africa, Egypt, Algeria, and Kenya. This concentration has direct consequences for both resilience and pricing.
Beyond fiber trenches, data centers, spectrum auctions, and AI model training pipelines, the next generation of African telecom infrastructure is being laid on the ocean floor.
Under the New Wave: Subsea Scales Fiber
Urban fiber deployment has accelerated sharply across the continent. South Africa leads Africa’s fiber development, with FTTH penetration surpassing 20% in urban areas, according to the Omdia Fiber Development Index 2025, with Johannesburg and Cape Town at the apex. Nairobi follows as East Africa’s standout, while Abidjan has emerged as the continent’s fastest mover, propelling Côte d’Ivoire from eighth to third in Africa’s fiber rankings in a single year.
Yet urban progress, however impressive, masks a widening divide. The economics of fiber deployment remain heavily skewed toward dense population centers where return on investment is fastest. Bridging that gap will require not just private capital but deliberate public policy: open-access frameworks, government-backed last-mile programs, and infrastructure-sharing mandates that prevent fiber networks from becoming the exclusive assets of the largest players.
As a result, submarine cable capacity is entering the fast lane. Systems including 2Africa—one of the longest submarine cable networks ever built—and Equiano are significantly expanding Africa’s international bandwidth. But the March 2024 simultaneous disruptions to the WACS, SAT-3, and ACE cables off the West African coast, which caused widespread outages in Nigeria and Ghana, served as a stark reminder that infrastructure diversity is not optional.
Thus, there is a need for a fundamentally different approach to network architecture built around resilience rather than efficiency alone. African operators and policymakers increasingly recognize that the cheapest route is rarely the most reliable one, and that the cost of downtime to businesses, health services, and financial systems far exceeds the cost of building in redundancy from the outset.
Alongside 2Africa, multiple systems are layering in redundancy. In mid-2025 alone, Telecom Egypt and NaiTel completed the Coral Bridge cable connecting Egypt and Jordan; Algérie Télécom and Sparkle signed an MoU to develop a new cable linking Italy and Algeria; and a consortium of four operators signed an agreement to construct the Asia-Africa-Europe-2 (AAE-2) system. Most recently, a consortium including Orange, Canalink, and regional operators announced the Via Africa submarine cable system in May 2026, designed to provide a different subsea route than existing infrastructure such as 2Africa, Equiano, and Medusa Africa, contributing to greater diversity and resilience for Europe-Africa connectivity.
Hyperscaler Sovereignty and Geopolitical Stakes
Historically, intercontinental submarine cables were built and governed by consortia of national telecoms operators. That model is rapidly giving way to hyperscaler dominance. Meta, Google, Microsoft, and Amazon collectively represent about three-quarters of active submarine cable capacity worldwide.
Meta’s Project Waterworth crystallizes this transformation. Spanning approximately 50,000 kilometers across five continents and linking the U.S., India, Brazil, and South Africa, Project Waterworth is designed to support AI and cloud traffic while bypassing geopolitical chokepoints such as the Red Sea and Suez Canal. Unlike many existing intercontinental cables, Waterworth’s route avoids hotspots where cable damage has previously disrupted East African connectivity.
For African governments and regulators, this consolidation raises legitimate sovereignty concerns. Infrastructure that carries the continent’s data is increasingly owned by a small number of U.S. technology companies, with governance structures that reflect their commercial priorities rather than African national interests.
The Price of Capacity
The relationship between submarine cable capacity and broadband affordability is one of the most consequential dynamics in African telecommunications.
A June 2025 report by the Foundation for Studies and Research on International Development found that doubling international subsea capacity can lead to an immediate 32% drop in fixed broadband prices and up to 50% for mobile broadband. For example, Egypt’s average monthly broadband cost of around USD 8 is directly linked to its position as a landing hub for over a dozen international cable systems, which drives down wholesale costs for service providers and, in turn, reduces consumer tariffs.
Industry analysts note that wholesale prices are falling as new cables come online, but the challenge now is ensuring that this connectivity reaches users at the last mile. For example, in Djibouti, despite hosting one of the highest concentrations of submarine cable landings on the continent, much of this infrastructure serves wholesale transit traffic for neighboring countries rather than reducing domestic retail prices, owing to the dominance of its state-owned operator. Without open-access landing station frameworks and genuine retail competition, the price benefits of new subsea capacity are captured at the top of the value chain.
The architecture of newer systems is beginning to address this structurally. The 2Africa system is designed as a fully open-access network, enabling operators and ISPs to purchase capacity directly rather than depending on a single gatekeeper. Alongside this, new carrier-neutral data centers are increasingly being clustered near major subsea cable landing stations and linked by high-capacity fiber rings, reducing latency and backhaul costs while enabling lower-latency services for enterprises and cloud providers.
The Foundation Beneath the Future
Africa’s telecom ambitions—universal connectivity, 5G-driven economic growth, a continent-wide digital economy—are achievable. But they will not be delivered by any single technology or any single operator; they will be delivered by the cables under the sea.
The subsea cable buildout underway represents the most significant transformation in the continent’s digital infrastructure since mobile telephony arrived in the 1990s. But capacity without distribution remains an abstraction; redundancy without policy coordination remains a vulnerability. The real challenge for Africa is whether African nations will assert enough agency over who owns them, who governs them, and who benefits when they come ashore.
The countries making the most progress today share a common characteristic: long-term, coordinated strategies that treat connectivity as critical national infrastructure, equivalent in importance to roads, power grids, and water systems. That framing shift, more than any individual technology, may prove to be the most consequential development of all.
