The America Samoa Hawaii Cable (ASH Cable) is the international fiber optic cable between American Samoa, Samoa and Hawaii and connects Samoa to the existing global telecommunications infrastructure networks.

The ASH Cable comprises of two cables installed between Samoa, American Samoa and Hawaii.

In addition, the Samoa-American Samoa Cable (SAS Cable) will provide inter-island communication, as well as enabling users in Samoa to access the ASH cable capacity and connect to the global networks.

While ASH Cable and SAS Cable are much smaller than the gargantuan systems across the North Pacific, they will provide more than 40 times the capacity currently in use in both island groups combined.

The ASH cable project is significantly different from the traditional submarine cable provisioning. The Samoan islands are in a fortunate position to re-utilize the former PACRIM East cable between Hawaii and Auckland that runs along the seabed, about 100 miles east of Pago Pago in the island of America Samoa.

The PACRIM East cable was the original fibre optic cable across the Pacific, laid in the 1990’s. It had large capacity then but by today’s standards its capacity is insufficient to effectively service the needs of New Zealand and Australia. As such, larger capacity cables – Southern Cross and Telstra Australia’s Sydney-Hawaii cables with capacities of Terabits – service their needs.

The project involves recovering the PACRIM East cable from the seabed south east of American Samoa, cutting it and laying it into American Samoa at Pago Pago. During the pick-up process, additional cable will be recovered for re-laying between Pago Pago and Apia, Samoa.

Major cost saving has been achieved in relaying the fibre cable as only a small section of the cable is being recovered and re-laid.

The ASH/SAS Cable consists of three cable landing stations, i.e., the Keawaula Cable Landing Station in Hawaii, the Pago Pago  Cable Landing Station in American Samoa, and the Apia Cable Landing Station in Samoa. The ASH/SAS Cable was ready for service on 28 May 2009.

Honotua is a 5000 Km submarine communications cable system that connects several islands of French Polynesia via Tahiti to Hawaii, USA. The international portion of the Honotua cable contains a single fiber pair designed with 32x10 Gbps DWDM system, with initial lit capacity of 2x10 Gbps. The domestic system comprises of 2 fiber pairs designed with 8x10 Gbps each, with an initial lit capacity of 2x2.5 Gbps. It has cable landing points at:

  • Vaitape,Bora Bora,French Polynesia
  • Uturoa,Raiatea, French Polynesia
  • Huahine, French Polynesia
  • Moorea, French Polynesia
  • Papenoo,Tahiti, French Polynesia
  • Spencer Beach,Kawaihae,

The Honotua Cable stretches 4,650 kilometers (2,890 miles) between Kawaihae, Hawaii and Tahiti, French Polynesia.

The baptismal name bestowed to this Polynesian project, HONOTUA, perfectly reflects the philosophy that lies behind it. HONO means link in the Tahitian language. It is the link between the human beings, peoples, cultures and civilizations. TUA means the open sea, the high seas. But it is also the back, the backbone. Thus HONOTUA is the link that relates Polynesian to the rest of the world, the backbone on which all the information channels interconnect.

Cable Landing Station is one important component of a submarine cable system which comprises of Wet Plant and Dry Plant.

The Dry Plant of a submarine cable system is a segment between the beach manhole and the cable landing station, comprises of land cable, power feeding equipment (PFE) and submarine line terminal equipment(SLTE), etc. The Wet Plant of a submarine cable system lies between the beach manholes, consists of submarine cable, repeater/gain equalizer, branching unit. A typical schematic of a submarine cable system is shown below.

Typical Schematic for a Submarine Cable System

The PFE and the SLTE of a submarine cable system are installed at the cable landing station. In some cases, the PFE is installed at a cable landing station nearby the cable landing site, while the SLTE may be installed in another cable landing station much faraway. For example, the terminal station at Hillsboro for the SLTE of the TPE cable system is about 150 mile away from the cable landing site at Nedonna Beach.

Multiple submarine cable systems may share the same cable landing stations. The submarine cable system is connected with the terrestrial network at the cable landing station, through the so called backhaul system.

The cable landing site is usually carefully chosen to be in areas:

  • that have little marine traffic to minimise the risk of cables being damaged by ship anchors and trawler operations;
  • with gently sloping, sandy or silty sea-floors so that the cable can be buried to minimise the chance of damage;
  • without strong currents that would uncover buried cables and potentially move cables.

Multiple types of submarine cables may be used in a submarine cable system, subject to depth of the seabed where the cable lies.

Various Types of Submarine Cables

The double armored submarine cable is used at the shore-end, terminated at the beach manhole at the cable landing site, and is interconnected with much lighter land cable going onward to the cable landing station.

There are now 9 international submarine cables landing in Malaysia, including APCN, APCN-2, AAG, SMW3, SMW4, FEA, and several cables between Malaysia and Indonesia such as Batam-Dumai-Melaka (BDM) Cable System, Dumai Malaka Cable System (DMCS) and Batam-Rengit Cable System (BRCS).

There are now five submarine cable systems landing in Vietnam, including AAG (Asia-America Gateway), TGN-IA (TGN Intra-Asia Cable System) and TVH (Tailand-Vietnam-Hong Kong) landing at Vung Tau Cable Landing StationC2C and SEA-ME-WE 3 cables landing at Danang Cable Landing Station.

There are now 10 submarine cable landing stations in India, with four in Mumbaithree in Chennai, and each in Cochin,Tuticorin and  Digha,

Currently, international submarine cables land in Thailand via 3 submarine cable landing stations, namely the Sri Racha Cable Landing Station, the Petchaburi Cable Landing Station, and the Songkhla Cable Landing Station.

The undergoing intra-Asia submarine cable system, South-east Asia Japan Cable (SJC) is going to land at the Songkhla Cable Landing Station.

The SEA-ME-WE 3 (SMW3) is currently the only international submarine cable system reaching Myanmar, landing at the Pyapon Cable Landing Station in Myanmar.

Cable Landing Stations in Brunei

There are two cable landing stations in Sri Lanka, the Mount Lavinia Cable Landing Stations for SMW3 and BLCS cable systems, and the Colombo Cable Landing Station for FALCON, SEA-ME-WE-4,SLT-Dhiraagu and SAFE cable systems.

The SEA-ME-WE-4 (SMW4) submarine cable system is currently the sole international optic fiber submarine cable landing in Bangladesh, with a cable landing station at Cox's Bazaar, built and owned by Bangladesh Submarine Cable Company (BSCCL) .

Since the landing of SMW4, the Internet infrastructure in Bangladesh has been significantly improved. The SMW4 is now the main link for the international internet gateway in Bangladesh, and is the truly and sole submarine internet cable in Bangladesh.

Mango, the only private sector international internet gateway (IIG) operator of Bangladesh, is connected to the global internet using the SEA-ME-WE 4 submarine cable system.  Mango won its license through an open auction from Bangladesh Telecommunication Regulatory Commission (BTRC) on February 25, 2008.

The Bangladesh Telecommunications Regulatory Commission (BTRC) issued draft licensing guidelines for two new submarine cable licences in early 2010. Each licensee should build a separate landing station within the general area of Khula-Patuakhali-Barisal-Chittagong, and should provide access, co-location and landing facilities to other submarine cable licensees, as and when required by the BTRC.

Besides the international submarine communication cable connecting Bangladesh, there are three terrestrial cables on India-Bangladesh boarders in Jessore, Sylhet-Comilla and Kurigram which may also bring Bangladesh into the global communication network.


Cable landing stations in the West Coast of the U.S. link most of the trans-pacific cables westward to Asia, Oceania, Hawaii, Guam, also connect with the submarine cables reaching Mexico and South America, as well as northward cables connecting Canada and the State of Alaska.

In the U.S., cables and cable landings are under the jurisdiction of the Federal Communications Commission and the U.S. Environmental Protection Agency (National Environmental Policy Act of 1969 [42 USC 4321-4327]). The U.S. Department of State also has a role. Cable Landing License is required to land a submarine cable in the U.S..

Guam is a natural hub and communication gateway for trans-Pacific telecommunications. On this 212-square-mile island, Guam arguably has one of the most extensive telecom infrastructures in the Asia Pacific region and most areas throughout the United States. There are currently 10 separate submarine cables with landing points in Guam, connecting Asia and Australia with the United States, via three cable landing stations in Guam -- Tumon Bay, Piti and Tanguisson -- allowing local interconnections to alternate routes and cable diversity. The cables landing in Guam include CUCN, AAG, AJC and Guam-Philippine at Tanguisson station, TPC-5, AJC and Pacrim West at Tumon Bay station, TGN-Pacific, TGN-IA and PPC-1 at Piti station.

There are 7 major transpacific submarine cables landing in Hawaii, distributed at 5 cable landing stations in Hawaii island, including

  • two cable landing stations in Kawaihae  of the Big Island, i.e., the Spencer Beach Cable Landing Station for the Honotua cable system and the other Spencer Beach Cable Landing Station for the Southern Cross cable system, and
  • three cable landing stations in Hanolulu island, i.e., the Kahe Point Cable Landing Station for the Southern Cross, the Makaha Cable Landing Station for the Japan-US CN, and the Keawaula Cable Landing Station for  TPC-5, Telstra Endeavour, AAG and ASH (American Samoa Hawaii Cable)


Because of the increasing importance of submarine cables, the Australian Government introduced legislation designed to protect the most critical submarine cables—the Telecommunications and Other Legislation Amendment (Protection of Submarine Cables and Other Measures) Act 2005. The legislation allows the Australian Communications and Media Authority (ACMA) to declare submarine cable protection zones in Australian waters over submarine cables of national significance. The ACMA has declared three submarine cable protection zones:

  • the Perth Submarine Cable Protection Zone stretching from City Beach, near Perth, to 51 nautical miles offshore (that is, to a water depth of 2000 metres) for the protection of the SEA-ME-WE 3 (SWM3).
  • the Northern Sydney Submarine Cable Protection Zone extending from Narrabeen beach to 40 nautical miles off shore covering northern branches of the Australia Japan Cable and Southern Cross cable, including the area between these two cables; and
  • the Southern Sydney Submarine Cable Protection Zone extending from Tamarama and Clovelly beaches and extending 30 nautical miles off shore covering the southern branches of the Australia Japan Cable and Southern Cross cables, including the area between these two cables.

American Samoa is an unincorporated territory of the United States located in the South Pacific Ocean, southeast of the sovereign state of Samoa (formerly known as Western Samoa).  The 2000 census showed a total population of 57,291 people. The total land area is 76.1 square miles (197.1 km2). American Samoa is the southernmost territory of the United States.

There is one international fiber optic cable between American Samoa, Samoa and Hawaii, the ASH/SAS Cable,  and connects America Samoa to the existing global telecommunications infrastructure networks.

The ASH/SAS Cable lands at the Pago Pago Cable Landing Station.

Samoa, officially the Independent State of Samoa, formerly known as Western Samoa and German Samoa, is a country encompassing the western part of the Samoan Islands in the South Pacific Ocean. It became independent from New Zealand in 1962. The two main islands of Samoa are Upolu and one of the biggest islands in Polynesia, Savai'i. The capital city, Apia, and Faleolo International Airport are situated on the island of Upolu.

Samoa is connected into the global submarine networks with the Samoa American Samoa Cable (SAS Cable), and onward connectivity with the American Samoa Hawaii Cable (ASH Cable).

The ASH/SAS Cable lands at the Apia Cable Landing Station.

French Polynesia is an overseas collectivity or constituent country of the French Republic. It is made up of several groups of Polynesian islands, the most famous island being Tahiti in the Society Islands group, which is also the most populous island and the seat of the capital of the territory (Papeete).

There are several cable landing stations in French Polynesia, including Vaitape, Uturoa, Huahine, Moorea and Papenoo cable landing stations.

The Papenoo Cable Landing Station in Tahiti island is the cable landing station for the Honotua submarine cable connecting French Polynesia and Hawaii, with onward connectivity to link French Polynesia with global submarine networks.

There are three cable landing stations in New Zealand, namely the Whenuapai Cable Landing Station, the Takapuna Cable Landing Station and the Auckland Cable Landing Station

It is currently only one submarine cable connecting New Zealand, i.e., the Southern Cross Cable Network which land at Whenuapai Cable Landing Station on the West Coast of New Zealand and the Takapuna Cable Landing Station on the East Coast of New Zealand.

The second international submarine cable system to link New Zealand is underway, i.e. the Pacific Fibre Cable System which is going to land in Auckland.

A Chinese consortium (China Telecom and Huawei Marine) announced in September 2011 to build a new trans-tasman submarine cable linking New Zealand and Australia, which will be the third submarine cable system landing in New Zealand.  


It is currently one international submarine cable linking Papua New Guinea, i.e., the PPC-1 cable landing at the Madang Cable Landing Station in Papua New Guinea.

The Southern Cross Cable Network is currently the only one international submarine cable landing in Fiji, and lands at the Suva Cable Landing Station in Viti Levu Island of Fiji.
