New Cape Town/Brazil subsea cable to boost SA broadbandDid you know that 98% of your global data travels under the ocean on subsea fibre optic cables, not via satellites? ![]() © Masoud Rezaeipoor 123RF Over 65% of South African’s, age 16+, is now online with an annual growth of over 7%. Video streaming, cloud storage, mobile phone, gaming etc. all need fast, secure, reliable global data streaming. South Africa’s demand for broadband is insatiable and we need infrastructure to support that growth. The good news is that USA-based Seaborn Networks has announced its plans to build the first and only, faster direct subsea fibre optic cable system to connect Cape Town (ie. South Africa) to Brazil with onward, direct (therefore faster) connectivity to New York, USA. We chatted to Seaborn’s COO Andy Bax to find out more about plans, relevancy, impact and operational decisions for this new ‘SABR’ system build between South Africa/Brazil/USA.
The decision to build from Cape Town to Brazil was a simple one. First of all, there is no direct route today from Africa to the US – a fact that when you consider the hundreds of submarine cables around the world is astounding. When we built Seabras-1 from the US to Sao Paulo in Southern Brazil we built additional on-ramps to the cable at strategic points along the route. One of these was in Northern Brazil. We have always considered that the most economically sound path for a cable route from South Africa to the US to be the shortest possible route across the Atlantic to a new, ultra-high capacity subsea fibre cable connecting to the US. Our South Africa to Brazil (SABR) cable is the shortest path across the Atlantic, landing in Northern Brazil with a direct connection into Seabras-1 to the US. This is also incredibly more stable than today’s existing routes which unfortunately seem to consistently suffer from faults, embargoes or acts of vandalism. A connection to Cape Town also provides for easier onward connections to the Eastern side of the continent as well as into Asia, all through existing subsea cables or those already under construction. An example of this is the recently announced agreement between Seaborn and IOX to jointly provide services between the US, South Africa, Mauritius and India through the two companies subsea fibre cables.

![]() South Africa and the continent as a whole will benefit from the SABR cable. Currently, telecommunications traffic bound for the US from South Africa traverses up either the East or West coast of Africa stopping off at numerous locations before going through the Middle East or southern and central Europe before going from Northern Europe to the US. ![]() Fast internet speeds for end consumers are basically defined by two factors. First of all, the amount of capacity that your service provider enables you to use directly impacts the “speed” at which you can interact online, be that streaming content or just downloading emails. A lack of capacity can result in content buffering as you try to stream it or downloads taking a very long time. The second factor, and one that is very important to content providers, gaming companies, and financial markets is the latency between the two endpoints on the network. Latency is the time for a piece of information to get from one end to the other and in telecommunications is measured in milliseconds.
![]() All telecom service providers will be able to benefit from the SABR project, be they small, medium, or large. Access to affordable capacity is critical to those companies being able to increase the bandwidth they provide to their end users whilst competing openly in the marketplace on service and price. It is important for these operators to realise the benefits of being involved and being involved early in the process to ensure that they get access to this valuable international capacity at cost on SABR, since once the cable is under construction that opportunity might well not be there.
