Overview
ATLANTIS-2 is a 12,000-kilometre submarine cable system crossing the South Atlantic Ocean, connecting South America to West Africa and onward to the Iberian Peninsula via a mid-ocean stop at the Cape Verde archipelago. With a design capacity of 160 Gbit/s, the system was built to carry traffic across one of the world's longer transoceanic routes — a corridor that bridges Latin American and African telecommunications networks with European hubs.
Route and Landing Points
The system makes landfall at six points. On the South American side, it lands at Las Toninas in Argentina and Fortaleza in Brazil — the latter a well-established cable hub on Brazil's northeastern coast, positioned to minimise distance across the South Atlantic. Moving east, the cable reaches Praia in Cape Verde, which serves as a critical mid-route node. On the African mainland, it lands at Dakar, Senegal, before continuing north to El Médano in Spain's Canary Islands and terminating at Sesimbra on the Portuguese coast.
This configuration gives the cable particular strategic value: it provides direct connectivity between Argentina, Brazil, and West Africa, a pairing that has historically been underserved relative to the North Atlantic. The Senegal landing also positions ATLANTIS-2 as part of the wider West African coastal connectivity ecosystem.
Ownership
ATLANTIS-2 is operated under a carrier consortium of 25 members. Named participants include Telintar, Embratel, Sonatel, Cabo Verde Telecom, Telefónica, Marconi, Telecom Italia, France Telecom, Deutsche Telekom, and Verizon. The breadth of the consortium reflects the cable's multinational scope, drawing in national carriers and major international operators from each of the regions it serves. Build details are not documented in available records.
Regional Significance
In the South Atlantic, where cable infrastructure is thinner than in the North Atlantic or Indo-Pacific, ATLANTIS-2 occupies a meaningful position. Its direct Argentina–Brazil–West Africa–Europe path offers a routing option distinct from cables that traverse only the North Atlantic or run solely along African coastlines.
