On key routes, the network is said to offer up to 180 terabits per second (Tbps) of capacity — more than all existing subsea cables serving Africa combined.

Meta says that in September 2025, the first live segments, including London, Ghana, Nigeria and South Africa, were expected to go live.

To achieve this scale, the engineering team introduced several cutting-edge technologies: spatial-division multiplexing (SDM) to double fiber capacity, undersea wavelength switching for flexible bandwidth, and a fleet of 35 offshore vessels whose combined operations total 32 years.

In remote landing areas, specialised diving and cable-burial equipment were deployed.

Beyond pure engineering, the economic implications are substantial. Research by RTI International estimates the system could contribute up to US $36.9 billion to Africa’s GDP within two to three years of going live.

Meta forecasts that faster, more reliable connectivity will fuel jobs, boost productivity, accelerate startup innovation and enable African businesses to access internet infrastructure at scale for the first time.

For partners such as MTN, 2Africa represents more than just upgraded cables and it embodies a vision of global tech companies working hand-in-hand with African operators.
