Angola Cables and Nokia announced at AfricaCom 2019 that they have collaborated to provide a direct optical connection between Africa and North America, by optically interconnecting MONET and South Atlantic Cable System (SACS). And the fiber-optic routing between Sangano in Angola and Boca Raton, Miami in the USA has completed final acceptance trial, with RTD of 123.4ms.

By optically interconnecting the deployed MONET and South Atlantic Cable System (SACS), Angola Cables is able to further reduce latency between content providers in North America and the rapidly growing data consumption markets in Africa.  For example, the connection between Johannesburg and New York City will be reduced by up to 18% using the direct SACS and MONET fiber optic connection.

Directly connecting the MONET and SACS cable systems through an express optical route - the first ever between Africa and North America - results in reduced latency between the continents and greatly simplifies the turn-up of services.

SACS, owned and managed by Angola Cables, consists of four fiber pairs between Fortaleza, Brazil and Luanda, Angola. The consortium-owned MONET cable system connects Fortaleza, Brazil with Boca Raton, Florida. Angola Cables owns two dedicated fiber pairs on the six fiber-pair MONET cable system.

Latencies on this network show improved performance, with the routing between Luanda, Angola and Miami, Florida having been reduced to 123.4ms, and between Cape Town and Miami to 162ms. Between Johannesburg and Miami, latency has been reduced to just 180ms.

The field trial leveraged Nokia's 1830 Photonic Service Switch wavelength division multiplexing (WDM) platform. Powered by the Photonic Service Engine coherent digital signal processor, the 1830 PSS successfully transmitted optical wavelength connectivity across the SACS and MONET cable systems over 12,635 km directly from Angola to Florida, reducing latency by 30% compared to existing routes.

The trial of this direct optical route between Africa and USA was successfully completed on 11 November 2019, and the network is available for commercial use.
