South Atlantic Cable System The South Atlantic Cable System is a submarine fiber-optic communications cable linking coastal points across the South Atlantic Ocean. The project involved multinational consortia, telecommunications carriers, and maritime engineering firms to provide high-capacity connectivity between Luanda, Cape Town, Santos, São Paulo, Buenos Aires, and other coastal cities, improving links between Africa, South America, and global hubs such as Lisbon and London.
The cable connects major ports and data centers in regions including Angola, Brazil, South Africa, and had coordination with entities in Portugal, Spain, United Kingdom, and United States. Designed with modern submarine engineering from firms like Alcatel Submarine Networks and alternatives such as SubCom, the system uses fiber-optic cable and Dense Wavelength Division Multiplexing technologies to deliver terabit-scale capacity. Key partners included national carriers such as Angola Cables, wholesale operators like Telefónica, and infrastructure investors drawn from Latin America and Africa.
Plans emerged amid discussions at multilateral forums involving representatives from Mercosur, Southern African Development Community, and the African Union. Feasibility studies referenced earlier transatlantic projects like Atlantis-2 and modernized initiatives parallel to MAREA and BRUSA. Financing negotiations involved state-backed entities, development banks tied to Banco do Brasil and private equity with ties to Infraco-type firms. Environmental assessments referenced protocols established by the International Maritime Organization and guidance from marine research institutions such as Scripps Institution of Oceanography and Ifremer.
The planned route traversed seabed topography mapped by institutions like GEBCO and surveyors using vessels akin to those operated by DOF Subsea and Fugro. Landing stations were sited at strategic ports including Luanda (Angola), Cape Town (South Africa), and Santos (Brazil), with potential branching units near Montevideo (Uruguay) and Bahia Blanca (Argentina). The system employed repeaters and optical amplifiers devised following standards from International Telecommunication Union and equipment from vendors such as Ciena and Huawei Marine Networks. Cable armoring and burial techniques referenced practices from Nexans and Prysmian Group.
Survey work used remotely operated vehicles and platforms similar to those from Schlumberger and contractors like DOF Subsea; installation required cable ships comparable to CS Dependable or Pierre de Fermat. Permitting involved port authorities in Luanda Port, Port of Santos, and Port of Cape Town, with environmental oversight by agencies akin to Brazilian Institute of Environment and Renewable Natural Resources and South African Department of Environmental Affairs. Onshore construction interfaced with data centers operated by companies such as Equinix and regional carriers including MTN Group and Claro (América Móvil). The final splicing and testing conformed to practices from the Institute of Electrical and Electronics Engineers and testing gear from Viavi Solutions.
Operations were managed through network operations centers that coordinate with carriers like Angola Cables, Telefónica, and Vodacom. Maintenance contracts engaged entities experienced in subsea repair such as SubCom and specialist vessels registered in flags associated with Liberia or Panama. Routine monitoring used optical performance parameters standardized by ITU-T and traffic engineering methods influenced by operators like Level 3 Communications and Tata Communications. Capacity leasing and peering arrangements involved exchanges similar to LINX and regional IXPs, with commercial models drawing on precedents set by Seaborn Networks and Telxius.
The cable altered bandwidth availability for markets tied to São Paulo, Luanda, and Cape Town, influencing digital services offered by firms like Mercado Libre and Vodafone, and supporting cloud providers such as Amazon Web Services, Microsoft Azure, and Google Cloud Platform through lower-latency routes. Strategic implications attracted attention from diplomatic actors in European Union capitals like Lisbon and Madrid as well as policy units in Washington, D.C. and Brasília. Trade organizations including World Trade Organization and development partners such as the World Bank monitored impacts on connectivity, foreign direct investment, and regional integration. Data sovereignty debates referenced frameworks from African Union and legal regimes influenced by decisions in courts like the European Court of Justice.
Submarine cables face hazards such as fishing gear interactions near continental shelves off Argentine Sea, anchor strikes near busy lanes around Cape Town Harbour, and seismic activity along segments close to the Mid-Atlantic Ridge and tectonic features monitored by US Geological Survey. Past transatlantic cable projects recorded disruptions resolved by repair ships coordinated with insurers like Lloyd's of London and classification societies such as DNV. Contingency routing involved cooperation with regional operators including Claro (América Móvil) and Telefonica Brasil to reroute traffic via alternative systems like South America-1 and Sat-3/WASC when outages occurred.
