The cable has been laid from South African waters and Mozambique and is now resting on the seabed of the Indian Ocean and the Red Sea, according to Brian Herlihy, the project's president.
"A third ship is currently being loaded with the remainder of SEACOM's deepwater cable which will be deployed from India towards Africa where the cable segments will be joined," Herlihy said.
Herlihy also said high-performance optical-transmission equipment, which connects customers to inland terrestrial networks, has been installed in Maputo, Mumbai and Djibouti landing stations.
The US$650 million cable project is expected to boost bandwidth and communication between the eastern and southern regions of Africa and the rest of the world.
Many African countries are still relying on satellite communications, which are blamed on the high cost of telecom in the region.
Herlihy said other life-enhancing disciplines such as education, clinical and scientific research, which rely on real-time sharing of data around the world, will also become a reality for many African organizations.
SEACOM is hurrying to beat the East African Submarine System (Teams) in the race to connection the eastern and southern African coasts to the rest of the world. Teams is a cable that is being constructed parallel to SEACOM and has Kenyan government support.
SEACOM, which is privately funded and three-quarters African owned, will assist communication carriers in Southern Africa and East Africa with wholesale capacity for global networks connecting to India and Europe.
