South Atlantic cable promises faster connectivity, lowest latency trans-Atlantic link

By Victor Magunamu, Kenya

The South Atlantic Cable System (SACS) is now on-stream and open for commercial traffic, promising faster connectivity between America and Africa. 

The new digital information highway is the first and fastest link between Africa and the Americas with the lowest latency and will provide a more direct routing for internet traffic in the Southern Hemisphere.

The new cable will see data transfer speeds improve five folds more existing cable routings, reducing latency from Fortaleza (Brazil) to Luanda (Angola) from 350ms to 63ms.Luanda will also connect to London and Miami with approximately 128 milliseconds 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 (USA) and Cape Town (South Africa) from 338ms to 163ms.

SACS is 100 per cent owned and managed by Angola Cables has been designed with 100Gbps coherent WDM technology on an end-to-end solution. With four fiber pairs it offers a total design capacity of 40 Tbit/s between Fortaleza Brazil and Angola.

The cable will also contribute to reductions in data traffic costs between South America and Africa, offering savings to operators that in turn, could be passed onto end-users and customers.

 ‘’Commercialisation of the cable is more than just a game-changer when it comes to data connectivity and services between the two continents, ’said António Nunes, CEO of Angola Cables.

He added that direct communications between Africa and the Americas will generate multiple advantages worldwide for internet service providers (ISP's), Cloud Service Providers (CSP's) and Over the Top Content Providers (OTT's) making use of these connections.

The new routing will dynamically change the internet traffic patterns within the Southern Hemisphere and combined with Monet & WACS, will dramatically alter global digital traffic routing options.

"Our ambition is to transport South American and Asian data packets via our African hub using SACS, and together with Monet and the WACS, provides a more efficient direct connectivity option between North, Central and South America onto Africa, Europe and Asia,’’ Nunes said.

The cable will enable African internet service providers and users a more direct, secure path to the Americas - without having to pass through Europe.

Content service providers in Latin America will also stand to benefit with the option of using the SACS route to reach markets in Africa and Europe without utilizing the traditional and high volume, Northern Hemisphere internet traffic routing.
