ATLANTIS-2 is a fiber optic transatlantic telecommunications cable connecting Argentina, Brazil, Senegal, Cape Verde, Spain's Canary Islands and Portugal.

It is the first submarine cable to link South America and the African continent.

Embratel, which organized the project, also installed two additional fiber pairs of 40 Gbit/s for its exclusive use between Fortaleza and Rio de Janeiro.

The cable was disconnected on 10 January 2022 due to a consortium decision, pending upgrades to 160 Gbit/s.
