Submarine cable operator offers customers greater choice with virtual private cables


CHICAGO – 6th May, 2018Angola Cables, a dedicated wholesale carrier, can now offer its customers customised amounts of capacity with Ciena’s (NYSE: CIEN) GeoMesh Extreme Spectrum Sharing capability. Angola Cables can reliably and securely offer highly differentiated virtual fibre pairs, which are dedicated and upgradeable portions of overall optical spectrum, to end-users over a shared physical fibre pair. Customers can access Angola Cables’ spectrum sharing capability on the MONET subsea cable, which is now live between Boca Raton, Fla. (Florida) and São Paulo, Brazil, with a branching unit extension to Fortaleza, Brazil.


Key Facts:

  • Angola Cables is one of the leading capacity providers for the African West Coast and is also a service provider on the MONET subsea cable, an Open Cable system, where each consortium member can select the submarine line terminals for its cable fibre pairs, providing customers greater flexibility and choice of technology.


  • Angola Cables’ customers can manage their own traffic and submarine line terminal equipment (SLTE) without the risk of impact to and from other users sharing the common open cable system. The primary benefit of Ciena’s Spectrum Sharing capability is that it provides secure, cost-effective, and reliable connectivity in the form of highly flexible spectrum partitioning allowing Angola Cables to offer virtualised fibre pair products to their end-customers.
  • Last year, Angolaselected Ciena’s GeoMesh Extreme with WaveLogic Ai and Blue Planet solutions and services to support its new service launch on the MONET subsea cable. The 10,556 km route currently provides more than 25 Tb/s of traffic on Angola Cables’ network between the U.S. and Latin America’s major business hub of São Paulo, Brazil.
