The Coral Sea Cable System (CS²) is a 4,700km long fibre optic submarine cable system linking Sydney, Australia, to Port Moresby, Papua New Guinea and Honiara, Solomon Islands. The project also includes a 730km submarine cable system connecting Honiara to Auki (Malaita Island), Noro (New Georgia Island) and Taro Island.
The four fibre-pair international system will deliver a minimum of 20Tbps capacity to Papua New Guinea and Solomon Islands respectively, a total capacity of 40Tbps. This will significantly augment Papua New Guinea’s existing submarine cable capacity. The Solomon Islands currently relies solely on satellite for international voice and data communications.
The Coral Sea Cable System (CS²) will be supplied and installed by Alcatel Submarine Networks (ASN), utilising ASN's 1620 SOFTNODE Submarine Line Terminal Equipment (SLTE) .
