The South Atlantic Cable System or SACS (Portuguese: Sistema de Cabo do Atlântico Sul),[4] is a submarine communications cable in the South Atlantic Ocean linking Luanda, Angola with Fortaleza, Brazil with a leg connecting the Brazilian archipelago of Fernando de Noronha as well.
[6] The undersea cable measures 6,165 km in length[2] and has been designed with 100 Gbps coherent WDM technology - with 4 fiber pairs and offers a total capacity of 40 Tbit/s between Brazil and Angola.
[8] With SACS cable now in operation, data traffic between Angola and Brazil will no longer have to pass through Europe and the US, as was the case previously.
It is expected that the SACS will cut data traffic costs between South America, Africa and onwards to Asia by 80%.
[2] According to its initiators it will have a lot of demand, mainly because it will be the first undersea cable in the South Atlantic linking the African continent to Latin America.
