SAEx is conceived as a system to link the developing economies of southern Africa and South America independently of traditional hubs and so to contribute to a link between
BRICS economic regions without recourse to traditional northern hemisphere hubs. It will also form a sub-sea route from
Indian Ocean network nodes in the Gulf region, India and Eastern Asia to South America and the USA while avoiding geological and geopolitical hazards present on other paths, such as the
oceanic trenches of the
Pacific Ocean, the
Red Sea, the
Suez Canal and the
Mediterranean Sea and transits through potentially unstable countries and unreliable overland transit networks. Currently,
internet traffic bounded from South Africa to the
Americas routes through
Europe. The SAex cable if constructed, will reduce
latency and
bandwidth costs associated with the distance that internet traffic currently has to travel by providing the shortest route possible from South Africa to the Americas. The initial design capacity of the cable is 40 TBit/s and will be over 10,000 kilometres in length (7,400 km from South Africa to Brazil and 3,000 km from Cape Town to Mtunzini). It will consist of four fibre pairs, each capable of carrying 10 TBit/s of data using 100 GBit/s wavelength technology. ==Campaign to connect St. Helena==
