Apollo is a 13,000 transatlantic submarine cable system. The Apollo cable system consists of 2 segments North and South, creating two fully diverse transatlantic paths. Apollo North connects the United Kingdom and the USA and Apollo South directly connects France and the USA.

Apollo was ready for service in February 2003, with a design capacity of 6.4 Tbps (3.2 Tbps on both North and South segments).

Apollo offers point to point 10 Gbit/s SDH and LAN PHY wavelengths between the major cities and carrier pops on the US Eastern seaboard and Western Europe.

The Apollo cable network is owned and operated by Apollo Submarine Cable System Limited, a UK based company jointly owned by Cable & Wireless Worldwide and Alcatel-Lucent.
