The consortium agreement was signed on June 5, 2010. The cable was manufactured by Alcatel Submarine Networks (ASN) and was laid by ships from ASN and France Telecom Marine. The first phase of the 17,000 km-long fiber optic cable was put in service on December 15, 2012, with an official inauguration ceremony held on December 19, 2012 in Banjul, The Gambia. However it was constructed only till the island of Sao Tome and Principle. The 5000 kilometers section northwards till South Africa has been taken up and is currently under construction with completion timeline of Q4 2019. MTN will be the landing party in South Africa and is expected to construct a new submarine cable landing station. The ACE Cable will eventually connect 23 countries, either directly for coastal countries or through land links for landlocked countries, like Mali and Niger. ACE is the first international submarine cable to land in Equatorial Guinea, The Gambia, Guinea, Liberia, Mauritania, Sao Tome and Principe and Sierra Leone. ACE consortiumThe current members of the consortium are:
Agreements are in place for the later entry of other operators or administrations along the cable route. TopologyThe ACE system uses wavelength division multiplexing (WDM) technology, which is currently the most advanced for submarine cables. With WDM, cable capacity can be increased without additional submarine work. With an overall potential capacity of 5.12 Tbit/s, the system will support the 40 Gbit/s technology from its launch. Landing pointsThe cable landing points are planned to be in the following countries and territories:[1]
Besides the above landing points, connectivity is extended to landlocked countries Mali and Niger via land links. See alsoList of international submarine communications cablesIndividual cable systems off the west coast of Africa include:
