South Atlantic submarine cable system to dramatically lower latency between Africa, South America

The $130-million South Atlantic Cable System (SACS) will reduce latency between Africa and South America from 300 ms to 63 ms once it is completed in mid-2018, says Angola Cables CEO Antonio Nunes.

The cable system, which traverses 6 500 km of the Atlantic between Fortaleza, Brazil, and Sangano, Angola, will have four fibre pairs, with 100 Gb/s by 100 Gb/s bandwidth on each pair, providing a total of 40 Tb/s of capacity.

It will also reduce data traffic costs between South America and Asia and improve the efficiency of Internet traffic between Africa and South America and that exchanged with North America.

In a teleconference on Friday, Nunes said the cable system would dramatically improve connectivity between the continents, but would also provide redundancy for connections between North America and Africa, via Angola Cables’ Monet submarine cable, which will connect Santos and Fortaleza, in Brazil, with Miami, in the US.

The 10 550 km, 20 Tb/s Monet cable will be complete by the middle of next year.

“In conjunction with the 14.5 Tb/s West Africa Cables System (WACS) – which traverses the western length of the African continent from Cape Town to London – we will be able to offer complete redundancy of Atlantic connections for our clients.

“The improved connectivity between the continents will help to boost services and business between the countries, and also help to establish Sangona and Fortaleza as connectivity hubs. In Fortaleza, we are building a large data centre, which will boost the information and communication technology ecosystem, specifically as a single point to support businesses in Africa and Brazil.”

The WACS was built by a consortium of 11 telecommunications carriers. Angola Cables manages the cable operations in Angola.

Nunes pointed out that agriculture, oil and gas, engineering services, telecommunications and science would be key beneficiaries of the improved connectivity as a result of the SACS, noting that expertise from the various territories, such as Brazil’s expertise in agricultural irrigation systems and US expertise in the oil and gas industry, could be leveraged to manage systems remotely and enable international companies to unify their organisations and staff.

The Square Kilometre Array radio telescope project would be able to use SACS to rapidly share large volumes of data and best practices with the Chilean Very Large Telescope optical telescope, helping to boost science and technology transfers between these premier astronomy projects.

Nunes added that the full capacity of the new generation-technology fibre-optic cable was not expected to be used immediately.

However, global experience has shown that excess submarine cable capacity is quickly consumed as Internet penetration grows, and technologies were used to improve the capacity of older submarine cables, indicating a sound commercial basis for the large capacity of the SACS.
