Submarine cable systems connecting Brazil and Africa

The South Atlantic Cable System (SACS) is a submarine cable system connecting Sangano in Angola and Fortaleza in Brazil, the world's first submarine cable system across the South Atlantic.

The SACS cable system consists of 4 fiber pairs, with an initial design capacity of 40Tb/s (100Gb/s x 100 wavelengths x 4 fiber-pairs), supplied by NEC.

The SACS is owned and operated by Angola Cables, established in 2009 as a wholesale network operator and a joint venture of five Angolan operators Angola Telecom (51%), Unitel (31%), MSTelcom (9%), Movicel (6%) and Startel (3%).

In addition to its operations in Angola and other countries, Angola Cables owns and operates a cable landing station in Forteleza (Forteleza CLS) and a Tier III carrier-neutral data center in Forteleza (AngoNAP Forteleza).

The Forteleza CLS is also a landing station for Angola Cables' MONET cable system connecting Brazil and the United States, which was ready for service in December 2017.

The SACS cable system was ready for service on September 26th, 2018.

In March 2023, Angola Cables rebranded its Brizilian operations as TelCables Brasil, aiming to increase and strengthen its local presence in Brazil and Latam, with full global support from the parent brand.
