2Africa is an international submarine telecommunications cable that interconnects Africa and further connects Asia and Europe. It passes from Europe through the Atlantic Ocean and Indian Ocean, and then back into Europe via the Red Sea and the Mediterranean Sea.
It is one of the first submarine cables to use spatial division multiplexing (SDM1) and has a design capacity of 180 Tbps across 16 fiber pairs. 2Africa is the largest subsea cable in the world, at 45,000 kilometers long, connecting 46 cable landing stations across 33 countries.
The system is to be constructed by Alcatel Submarine Networks and is intended to be operational in Q4 2025. In November 2025, Meta announced that the core 2Africa system was completed.
