Subsea cable launch promises South Africa improved internet

A new fast submarine cable connecting Africa and South America has been launched. The South Atlantic Cable System (Sacs) is the first subsystem across the Southern Atlantic Ocean says Techcentral. 

The Sacs will provide lower latency between South Africa and key internet markets of the US.

Angola cables said in a statement “the new digital information highway is the first and fastest link between Africa and the Americans with lowest latency and will provide more direct routing for internet in the Southern hemisphere”.

These developments will have a noticeable impact for “future growth and configuration of the global internet”.

The cables are constructed by the NEC and connect Brazil and Angola and have onward connectivity to North America on other systems.

“Data transfer speeds will be greatly improved (five times faster than existing cable routings), reducing latency from Fortaleza (Brazil) to Luanda (Angola) from 350 milliseconds to 63ms,” the company said.

“Luanda will also connect to London and Miami with approximately 128ms latency. These two major content hubs will position Angola as a strategic point to serve the transatlantic region with low latency and resilient connections.

“Given the onward connections to the recently completed Monet Cable and the West Africa Cable System (Wacs), Sacs will also offer reduced latency between Miami and Cape Town from 338ms to 163ms.”

The new routing will “dynamically change” the Internet traffic patterns in the southern hemisphere and combined with Monet and Wacs, will “dramatically alter global digital traffic routing options”, said Angola Cables CEO António Nunes. “Sacs is a new thoroughfare for data between networks, major content providers and some of the fastest-growing markets for data consumption.”

“Our ambition is to transport South American and Asian data packets via our African hub using Sacs, and together with Monet and Wacs, provide a more efficient, direct connectivity option between North, Central and South America and on to Africa, Europe and Asia,” Nunes said.

“By developing and connecting ecosystems that allow for local Internet protocol traffic to be exchanged locally and regionally, the efficiency of networks that are serving the southern hemisphere can be vastly improved. As these developments progress they will have considerable impact for the future growth and configuration of the global Internet.”
