ACE deploys the latest fiber optic technology developed by Alcatel-Lucent. Fiber optic offers better high-speed broadband internet quality than satellite and at a lower cost. The ACE cable will extend over 17,000 km from Penmarch in Brittany, France, to Cape Town in South Africa, at depths close to 6,000 meters below sea level.

Its wavelength-division multiplexing (WDM)technology, makes it possible to increase its capacity according to various needs and to the latest technological improvements by upgrading station equipment without any submarine cable modifications. With a potential capacity of 5.12 Tbps made possible by the new 40 Gbps technology, ACE will be able to evolve with new technological developments using regular upgrades. The ACE system will also facilitate connectivity with terrestrial fiber optic cables.
