PPC-1 (PIPE Pacific Cable 1)

TGA (Tasman Global Access ) 

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.


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 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.

Tasman Global Access (TGA) is 2300km submarine cable system connecting New Zealand and Australia.

Recovery and Reuse of PacRimWest for APNG-2

The APNG-2 is a 1800km submarine cable linking Papua New Guinea directly to Australia and indirectly to New Zealand and the rest of the world. The APNG-2 cable system was ready for service late 2006.

The APNG-2 cable lands at:

  • Ela Beach, Port Moresby, Papua New Guinea
  • Narrabeen, Oxford Falls, Sydney, Australia

The APNG-2 consortium comprises Telikom PNG, Telstra, and Telecom New Zealand.

The APNG-2 cable system was built by recovery and reuse of an 1,800 km section of the PacRimWest cable, which was recovered from just south of Guam, with the ship sailing towards the Solomon Islands.

The ship then recovered a loop of the PacRimWest cable off Rockhampton, Queensland, broke it, and spliced it to the Sydney end of the recovered 1,800 km section, sailed towards PNG, made landfall at Ela Beach near Port Moresby, where a terminal station from Guam was re-established to link to the Telikom PNG network.

PacRimWest is a fibre-optic cable with two fibre pairs. These were used to provide APNG-2 with around 1100 Mbit/s data capability, consisting of 2 x 565 Mbit/s PDH systems with all electronic regeneration.

The cost of the APNG-2 cable system would be about US$60million, it was finally about US$11million. Reuse of the PacRimWest cable saved about 80% of the cost of a new cable.



PacRimWest was a twin-pair 560Mbit/s optical submarine cable connecting Australia to Guam, for a total length of 7,062km.

PacRimWest was constructed in 1994 and was came into service on 31 January 1995. 

PacRimWest was designed to have an operational life of 25 years, but it was decommissioned from service in 2005.

After decommissioning in 2005, the PacRimWest cable was cut near the Solomon Islands and relaid to form APNG-2 in 2006 connecting Sydney and Papua New Guinea, saving PNG around 80% of the cost of building a new cable and plant with the equipment from the Guam landing station being moved to PNG.

The Tonga-Fiji Submarine Cable System (also known as Tonga Cable) is a 827km fiber optic submarine cable system linking Nuku'alofa, Tonga and Suva, Fiji, and connects to the Southern Cross Cable Network at the Suva Cable Landing Station in Fiji.

The Tonga-Fiji Submarine Cable System is owned and operated by the state-owned Tonga Cable Limited (TCL), which was set up in 2011 to develop, and manage the submarine cable with financing support by Asian Development Bank (ADB) and the World Bank.

According to ADB report, the total project cost was estimated at $32.8 million, with ADB contributing $9.7 million, the World Bank $16.5 million, and the government $6.6 million. Total investment costs equaled $32.4 million and consisted of civil works ($4.2 million), procurement of the submarine cable system (estimated at $26.2 million), consulting services ($1.2 million), and taxes and duties ($0.8 million). Recurrent costs totaled $0.4 million, consisting of salaries, office space, and equipment operation and maintenance.

TCL signed a single (turnkey) contract valued at $18.8 million to install the international cable between Tonga and Fiji—lower than the estimated contract value of $26.2 million. By project completion, the final contract value had increased to $21.4 million to cover the purchase of additional cable equipment needed for installation. The original works were completed on time and within budget, with a saving of $4.58 million, of which 49.9% ($2.28 million) was ADB’s and 50.1% ($2.29 million) the World Bank’s.

The Tonga-Fiji Submarine Cable System is supplied by ASN, ready for service on 21 August 2013.


Tonga Domestic Cable Extension (TDCE)

With the saving of $4.58 million and additional fund of $7.0million by the Tonga Government, the Tonga Cable was extended domestically from Tonga Isaland to Vava’u (additional 348 km) and Ha’apai (a further 58 km), at a total cost of about $11.0 million. To fund the Tong Domestic Cable Extension (TDCE), the government of Tonga sold 16.7% of TCL shares to Digicel Tonga Limited (Digicel) for $4.2 million. The Tonga Domestic Cable Extension was also supplied by ASN and ready for service in January 2018.

Tonga Communications Corporation (TCC) and Digicel Tonga Limited  are leading operators in Tonga.

TCC is a state-owned enterprise (SOE), provides fixed line, mobile and internet services in Tonga. 

Digicel Tonga Limited is part of Digicel Pacific Limited (DPL), wholly-owned subsidiary of Digicel Group Holdings Limited (DGHL) which operates in 32 markets in the Caribbean, Central America and Pacific. In October 2021, Telstra acquired Digicel Pacific Limited for US$1.85 billion.
