EllaLink is an optical submarine cable linking the European and South American continents with landing points in Sines in Portugal and Fortaleza in Brazil.

It has currently the lowest latency (<60 ms round-trip delay time between Portugal and Brazil) on the market.

The only cable linking the two continents was Atlantis-2, which was not used for Internet data transfer due to its limited capacity.
