Malbec is a new 2,500 km submarine cable that links the Brazilian cities of Rio de Janeiro and Sao Paulo to Buenos Aires, the capital of Argentina and will have a branching unit to reach Porto Alegre, Brazil.

By connecting Argentina to GlobeNet’s network in Brazil, the new infrastructure will provide seamless connectivity between the Southern Cone of South America and the United States. When completed, it will be the first new submarine cable route to reach the Argentinian coast since 2001.

The Malbec cable system is co-owned by GlobeNet and Facebook, and it will be operated by GlobeNet. "Malbec" is named after the renowned Argentinian wine.

The Malbec cable system has been put into service as of June 1, 2021.
