First-Ever Southern Transatlantic Cable In Service Soon

The first transatlantic broadband submarine cable in the southern hemisphere, the South Atlantic Cable System (Sacs), will begin carrying its first commercial traffic within the next three months, providing a more direct and lower-latency route between South Africa — and other African markets — and the US.

In a podcast interview with TechCentral on Thursday, António Nunes, the CEO of Luanda-based Angola Cables — the main backer of the Sacs cable — said the system has been built and testing has begun.

The 6 300km Sacs cable, which has a design capacity of 40Tbit/s using 100Gbit/s dense wave-division multiplexing technology and is made up of four fibre pairs, connects Luanda in Angola to Fortaleza in Brazil. From there, it connects to the 10 000km-plus Monet cable, which runs between Miami in the US and São Paulo in Brazil.

Nunes said the new route will slash latency — or network round-trip round times — between Africa and Brazil and Africa and the US. Until now, Internet traffic between Brazil and South Africa, for example, had to traverse Europe, cross the north Atlantic to the US and then hop onto cable systems linking South America.

“A lot of software and systems that are latency dependent will be using this connectivity,” he said. The new route will offer the lowest latency between South America and Asia via other systems in the Indian Ocean.

“From the point that Sacs is operational, South America will be able to connect to Europe, avoiding the US, and to Asia, avoiding the US and Europe.”

There will also be a ring in the Atlantic Ocean, providing an alternative route to the northern transatlantic systems.

Nunes expects to finalise testing of Sacs by the end of July or early August. “One issue is the data centre in Fortaleza is a little bit late (in construction), so we need a way to start deploying the service on the Sacs system before the data centre is ready. It will not be later than September.”
