Subsea Cables Connecting Asia and Australia


There are the following subsea cable systems connecting Asia and Australia: 



ASC (Australia-Singapore Cable)

AJC (Australia-Japan Cable)

JGA (Japan-Guam-Australia)


OAC (Oman Australia Cable)

PNG National

Coral Sea (CS²)

Trident (pending)

The AJC Network (Australia Japan Cable Network) is a 12,700km submarine cable network connecting Australia, Guam and Japan, with two fiber pairs.

The AJC network was initially designed with 10 Gbps DWDM technology, with a design capacity of up to 64 waves per fibre pair over two fiber pairs. The AJC network runs through the six AJC cable landing stations, with two separate cable landing stations in each of  Japan, Australia and Guam. The AJC Network was ready for service on 30 December 2001.

The AJC network was upgraded the addition of 40G technology in mid 2012 and the addition of 100G technology in late 2013 and early 2014.  During 2018 AJC was upgraded with latest optical coherent technology to be equipped with some 5Tbps Australia-Guam-Japan. 

The Design Capacity of AJC is currently approximately 10Tbps.

The JASURAUS submarine cable system (also know as APCN Australian Extension) connects Australia (Port Hedland) with Indonesia (Jakarta), with total cable length of 2800 km and a design capacity of 5 Gbps. and brings Australia to the Asia Pacific Cable Netwoen/systems/intra-asia/apcnrk (APCN).

For more information about the JASURAUS, please refer to APCN cable system overview.

The ASSC-1 submarine cable system is a new cable connecting Australia, Indonesia and Singapore, comprises four fibre pairs and spans a distance of 4,600 km.

The ASSC-1 consists of three express fiber pairs directly linking Perth and Singpare and one omnibus fibre pair between Perth, Jakarta and Singapore.

The ASSC-1 cable system will have an initial design capacity of 6.4 Tbps, running at 40 Gbps technology, with the capability to be upgraded to 100 Gbps in the future.

The ASSC-1 cable system is scheduled to be ready for service by the end of 2013.

Papua New Guinea is an island nation located in the South Pacific. The PNG National Submarine Cable Network is built and operated by PNG DataCo Limited, connecting 14 main cities in PNG, and with international connectivity by a link to Jayapura in Indonesia, and interconnection with PPC-1 at Madand cable landing station, onward to Guam and Sydney, Australia. 

The design capacity of the system is 8Tbps. And it is expected to be completed in 2018.

Trident Cable System is a 28 Tbps subsea cable, using 100Gbps coherent DWDM technology upgradeable to 400Gbps technology in the future, which will connect Australia, Singapore and Jakarta.

The Trident cable will have interconnection points in Equinix IBX data centres in Sydney, Melbourne, Singapore and Jakarta, as well as a landing point in Perth, providing greater connectivity for businesses, content providers and communications network providers.
