South Africa: ACE Submarine Cable Extension Enters Service In South Africa, Upgrades Capacity To 20 Tbps

The Africa Coast to Europe (ACE) submarine cable consortium announced that the 4,000-km segment connecting Sao Tomé & Principe to South Africa was put into operation as of 1 June 2021, according to a company press release. In South Africa, the cable landing station is located in Duynefontein, close to Cape Town, and is connected by terrestrial fibre to the Terraco CT1 data centre. The ACE consortium, Orange and Alcatel Lucent officially announced the start of the Phase II extension of the ACE submarine cable system in November 2015 (see Africa: ACE Consortium Announces Launch Of Phase II, From Sao Tomé & Principe To South Africa).

The ACE cable first entered service in December 2012 (see Africa: France Telecom Orange Announces Launch of ACE Submarine Cable), connecting 13 countries from France to Sao Tomé & Principe: France, Portugal, Mauritania, Senegal, The Gambia, Guinea, Sierra Leone, Liberia, Côte d'Ivoire, Ghana, Equatorial Guinea, Gabon and Sao Tomé & Principe. Two landlocked countries, Mali and Niger, were also connected through extensions to the terrestrial network. In July 2015, the ACE submarine cable also entered service in Benin and the Canary Islands (see Benin: ACE Submarine Cable Enters Service In Benin And The Canary Islands (Spain)). In addition, a new festoon submarine cable connecting Guinea Bissau to the ACE cable in Dakar (Senegal) is also under construction (Guinea Bissau: ACE Festoon Cable Lands In Guinea Bissau, Due To Enter Service By End 2020).

ACE also announced an increase in the total design capacity of the entire submarine cable system from 12.8 Tbps to 20 Tbps. When the ACE submarine cable entered service in 2012, it had an initial design capacity of 5.12 Tbps using 40 Gbps technology. In January 2015, Alcatel-Lucent and the ACE consortium announced that they had successfully completed a field trial using 300 Gbps and 400 Gbps technology, demonstrating a more than a fivefold increase in the system’s design capability (see Africa: Alcatel-Lucent and Africa Coast to Europe Consortium Complete Field Trial of 300G/ 400G Technology).
