With 45,000 km and 180 Tbps, 2Africa is the largest submarine cable in the world, connecting Africa, Europe, and Asia and revolutionizing the global internet infrastructure.
Under the planet’s oceans, where sunlight does not reach and pressure can crush steel, runs one of the greatest engineering feats of modern times, an invisible structure that keeps the world connected. This is 2Africa, the largest submarine internet cable system ever built, with 45,000 kilometers in length and transmission capacity reaching 180 terabits per second (Tbps). The project, led by a global consortium of telecommunications and technology companies, aims to connect Africa, Europe, and Asia, forming a digital ring around three continents and revolutionizing network access in dozens of emerging countries.
A Project That Changes the Digital Geography of the Planet
Announced in 2020 and under construction since 2022, 2Africa is a project of unprecedented scale. Its length is equivalent to more than a complete trip around the Earth and covers 46 connection points (“landings”) in 33 countries, including Egypt, Spain, Nigeria, South Africa, Saudi Arabia, Oman, India, and France.
According to the responsible consortium, the cable’s main mission is to increase internet capacity in Africa by 16 times, a continent where cost and infrastructure limitations still impede full digital inclusion.

With a cost per shot close to zero, the DragonFire laser could change naval warfare in 2027 and provide British ships with nearly unlimited defense against drones.
-
A British startup creates tires that generate electricity in electric vehicles when passing over potholes, speed bumps, and cracks.
-
Scientists have created robots made with living cells that have their own nervous system, swim on their own, explore the environment, and self-organize without any genetic engineering, and now they want to do the same with human cells.
-
Students create a solar-powered ambulance that operates without a plug, without fuel, and still keeps medical equipment running in remote areas.
2Africa is expected to connect 1.2 billion people more quickly and stably, reducing dependence on terrestrial and satellite networks.
The project is led by giants such as Meta Platforms (Facebook), Vodafone Group, China Mobile International, Orange, STC (Saudi Telecom Company), and Telecom Egypt, supported by companies specializing in ocean cables like Alcatel Submarine Networks (ASN).
The goal is for the entire system to be fully operational by 2025, with the final connections being activated on the Mediterranean coast and the Arabian Peninsula.
A Colossal Underwater Engineering
Building a global submarine cable is a challenge comparable to launching a rocket into space. 2Africa consists of 16 pairs of optical fibers encapsulated in multiple layers of insulation, shielding, and metallic armor.
Each centimeter is designed to withstand deep ocean pressure, corrosion, and even shark bites — a real risk documented in other cables.
During installation, specialized ships map the seafloor with sonar to define safe routes, avoiding underwater volcanoes and geological faults.
The cable is then slowly unwound from the deck, descending to the ocean floor and being buried in some segments near the coasts to avoid damage caused by anchors or fishing.
The maximum depth of 2Africa reaches 8,000 meters, and the project has already been classified by PR Newswire and Reuters as “the largest submarine optical fiber network in human history”.
Connecting Three Continents and Hundreds of Millions of People
The name “2Africa” is not casual; the goal is to transform the African continent into the new global digital hub, connecting it to European and Asian networks with low latency and high speed.
The circular structure directly links the Mediterranean Sea, the Red Sea, the Indian Ocean, and the Atlantic, creating an unprecedented redundancy route: if one segment fails, traffic can be automatically redirected from the other side of the ring.
This architecture is considered interruption-proof, ensuring the system a reliability of 99.999%, a standard required in critical applications such as banks, stock exchanges, and defense systems.
According to Vodafone Global Enterprise, 2Africa could increase Africa’s GDP by up to US$ 26 billion per year after its completion, thanks to the expansion of e-commerce, distance education, and digital financial services.
A Landmark for the New Technological Race
The 2Africa project is also a reflection of the new geopolitical competition for global connectivity. Just as ports and pipelines were strategic in the 20th century, submarine cables have now become the “data pipelines” of the 21st century.
Today, over 98% of all international internet traffic travels via submarine cables, rather than satellites, as many assume. This includes messages, calls, videos, banking transactions, and military communications. In this context, 2Africa is a tool of economic and diplomatic power:
- For Meta, it ensures technological autonomy against rivals like Google and Amazon, which operate their own global networks.
- For China Mobile, the project strengthens China’s presence in African and Middle Eastern countries.
- For Vodafone and European operators, it represents the opportunity to diversify routes and reduce interconnection costs.
The result is a network with a direct impact on the global economy — and strategic importance comparable to that of the Suez Canal or the ancient Silk Road.
The Future Is Already Connected
The first segments of 2Africa have been active since 2023, with confirmed landings in the United Kingdom, Spain, Egypt, Kenya, and South Africa. The next steps include connections in the Persian Gulf, off the Indian coast, and in the Arabian Sea, consolidating total coverage by 2025.
In addition to expanding internet access, the system will serve as a foundation for 5G and 6G networks, data centers, and cloud computing, consolidating the digital infrastructure of three continents interconnected by a single submerged “ring of light.”
More than an engineering feat, 2Africa represents an invisible revolution: a cord of glass and light that stitches together continents, economies, and people in real-time.
Under the seas, where only ships once crossed, now lies the true route of the 21st century — the data route.
