Subsea Cables in/across South Pacific
There are now the following subsea cable systems in or acroos South Pacific, connecting Asia, Australia, New Zealand, the South Pacific Islands, and the United States.
Southern Cross Cable Network (SCCN)
Southern Cross Next (under construction)
PPC-1 (PIPE Pacific Cable 1)
TGA (Tasman Global Access )
PPC-1
The PPC-1 (PIPE Pacific Cable 1) submarine cable system consists of two segments of digital fiber-optic cable: (1) the Australia-Guam Trunk, connecting Sydney, Australia with Piti, Guam; and (2) the PNG Spur, connecting Madang, Papua New Guinea with a branching unit located on the Australia-Guam Trunk. The Australia-Guam Trunk of the PPC-1 cable system consists of two optical fiber pairs, with a design capacity of 96 wavelengths (10 Gbps) on each fiber pair, for a total design capacity of 1.92 Tbps. The initial configuration of the Australia-Guam Trunk provides a total of 140 Gbps of capacity. The initial configuration of the PNG Spur provides a total of 20 Gbps of capacity, 10 Gbps on the Papua New Guinea-Guam route and 10 Gbps on the Papua New Guinea-Australia route.
The PPC-1 cable project was lunched on January 14, 2008. On September 22, 2009, Internode released a press release claiming successful transmission of IP packets across the PPC-1 cable, making it the first commercial entity to make use of the PPC-1 cable. The PPC-1 cable project was formally completed on October 8, 2009.
Pacific Fibre
The Pacific Fibre cable is a new 12,750km (7,920 miles) trans-pacific subsea fiber optic cable linking Australia, New Zealand and the US, with cable landing stations in Sydney, Auckland and Los Angeles. The Pacific Fibre cable system consists of two fiber pairs, with 128 wavelengths per fibre pair. By using the latest 40 Gbps per wavelength technology, the Pacific Fibre is expected to have a capacity of up to 5.12 Tbps, and will be further upgradeable to beyond 12 Tbps with future 100 Gbps per wavelength technology.
The Pacific Fibre is the second international submarine cable system landing in New Zealand, with significant improvement to the international network resilience in New Zealand.
The Pacific Fibre is expected to be ready for service in 2014.
Unfortunately, the Pacific Fibre has ceased operation as at 1 August 2012, citing an inability to raise enough investment to fund the cable build.
Optikor Network
Optikor Network is a new trans-Tasman submarine cable system connecting Sydney, Australia with South Island and North Island, New Zealandlink, with a cable length of more than 3000 km. The trans-Tasman Optikor Network is designed to provide initially a capacity of 120 Gbps with 1 fiber pair, and eventually 6.4 Tbps with 2 fibre pairs.
Axin Limited initiated the trans-Tasman Optikor Network in September 2011. Axin Limited, founded in 2010, is fully invested by the Sino Telecommunication, and plays major role in the national broad band project of New Zealand.
The trans-Tasman Optikor Network is expected to be ready for service by the end of 2013.
This trans-Tasman Optikor Network will address the large capacity requirements in the Tasman region and bring competition to the capacity markets in Australia and New Zealand where are now dominated by the Southern Cross Cable Network and the undergoing Pacific Fibre.
KSCN
The Kumul submarine cable network (KSCN) is a 5,457-km domestic internet platform to link fourteen provinces and two national data centres in Port Moresby and Madang, Papua New Guinea (PNG). The KSCN also connects to Jakarta through Indonesia’s national backbone submarine cable network and further connect to Asia to form a new international internet gateway.
Located in the South Pacific, Papua New Guinea is an island nation with numerous mountains and volcanoes, where domestic telecommunications largely relies on satellite and microwave communications. Huawei Marine and PNG DataCo Limited, a Telecommunications Carrier established by the PNG Government, constructs the national submarine cable network to provide the backbone telecommunications needed by major coastal centers and islands in Papua New Guinea
The KSCN project, part-funded by the Chinese government. The PNG government approached China for funding support and the Chinese Exim Bank provided 85% preferential buyers credit to the PNG government to carry out the project.
