  • 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.

  • The Bifrost Cable System is a trans-pacific cable system connecting Singapore, Indonesia, the Philippines, the United State (Guam, Gorover Beach, Winema) and Mexico, with its main trunk linking Singapore to the United States over 16,460 km via Indonesia through the Java Sea and Celebes Sea, and total cable length of 19,900km inclusive of its branches.

    Bifrost consortium comprises Meta (Facebook), PT. Telekomunikasi Indonesia International (Telin), Keppel Telecommunications & Transportation Limited (Keppel T&T) and Amazon (through its subisidiary AMCS LLC).

    Keppel T&T, through its wholly owned subsidiary Keppel Midgard Holdings Pte. Ltd. (KMH), participates in the Bifrost consortium as its first direct investment in a subsea cable system, and has acquired a Facilities-Based Operator (FBO) licence issued by the Infocomm Media Development Authority of Singapore (IMDA). The FBO licence allows KMH to own, maintain and operate telecoms infrastructure in Singapore and to provide telecommunications services in connection with the Bifrost cable system. KMH's share of the total project costs as a joint build partner is approximately US$350million (or approximately S$467 million), according to Keppel's announcement.

    The whole initial cost of the Bifrost cable system is expected to be approximately US$760million, estimated by

    KMH has sold Converge ICT Solutions Inc. (Converge) one fiber pair on the main trunk of the Bifrost cable system on IRU-basis for over US$100 million (around PhP 5 billion). Converge acts as the landing partner to land the Bifrost cable system in Davao, the Philippines, and is granted an IRU on the entire Davao branch.

    The Bifrost cable system is supplied by Alcatel Submarine Networks (ASN).

    Originally expected to be completed in Q2, 2024, the Bifrost project has been delayed due to bad weather and difficulties to get permits for the cable to land in Indonesia and pass Indonesian waters. And Telin didn't start building the cable landing station in Jakarta for the Bifrost cable system until early June, 2024.

  • The Bulikula submarine cable connects Guam with Fiji.

    Bulikula is the Fijian word for “golden cowrie,” a rare shell found in the Pacific Ocean often worn by local chieftains as a badge of rank.

    The Bulikula submarine cable system is part of Google's Central Pacific Connect initiative which includes Bulikula and Halaihai linking Guam and French Polynesia.

    Google's Central Pacific Connect initiative is originated from the Central Pacific Cable project, which demonstrates a strategic initiative of the United States to connect various Pacific islands and boost the U.S.’s interests in the Pacific region, where it competes for influence with China.

    Google partners with Telstra, APTelecom, and Amalgamated Telecom Holdings (ATH) on the Bulikula submarine cable system and the Central Pacific Connect initiative. 

    Amalgamated Telecom Holdings Limited (ATH) was incorporated as a public company in March 1998, as a vehicle through which the Fiji government's investments in the telecommunications sector was consolidated for the purpose of privatisation under its public sector reform programme. 

    Telstra owns and operates a fibre pair on the core trunk on the Bulikula cable connecting Guam and Fiji.

  • The CAP-1 cable system is a 12,000 kilometers submarine cable system connecting California, USA and Pagudpud, Philippines.

    The CAP-1 cable system will land at: 

    The CAP-1 cable system consists of six fiber pairs and a single trunk of 12,000km, with a design capacity of 90 waves x 200 Gbps (or equivalent) per fiber pair using current technology, with an aggregate design capacity of 108 Tbps, to be supplied by NEC.

    The CAP-1 cable system is de facto reconfigured BtoBE cable system. Due to geopoliticial tensions and US concerns on national security, the BtoBE consortium withdrew the application for cable landing license in the United States in September 2020. Meanwhile, the same applicants including Facebook, Amazon and China Mobile filed with the FCC a new application to land and operate the CAP-1 cable system connecting the United States and the Philippines. China Mobile would own three out of the six fiber pairs of the system, Facebook two and half fiber pairs, and Amazon half fiber pair. 

    On August 9, 2021, Facebook and Amazon filed with the FCC an amended application, removing China Mobile International Limited (China Mobile) as an applicant for the FCC cable landing license of the CAP-1 cable system. Pursuant to an agreement executed on August 8, 2021, China Mobile agreed to transfer to Facebook and Amazon all rights, title, and interests in relation to the facilities between the Grover Beach, California landing point and the reconfiguration demarcation point off the coast of the Philippines. And Facebook and Amazon also agreed to assume all related obligations and liabilities. As a result, Facebook and Amazon would own five fiber pairs (83.3333%) and one fiber pair (16.6667%) out of the total six fiber pairs respectively.

    As reveiwed and investigated by the US Team Telecom, China Mobile International was deemed to stay in the CAP-1 cable system.

    On April 19, 2022, Facebook and Amazon notified the FCC of the withdrawal of the above amended application, and requested that the FCC dismiss the application without prejudice to any future filings for the same or similar.

    The East Micronesia Cable System (EMCS) is jointly owned and operated by FSM Telecommunications Cable Corporation (FSMTCC), based in the Federated States of Micronesia (FSM), BwebwerikiNet Limited (BNL) of the Republic of Kiribati, and Nauru Fibre Cable Corporation (NFCC) of the Republic of Nauru.

    The East Micronesia Cable System (EMCS) is supplied by NEC.

    The EMCS project costs approximately US$95 million (AU$135 million equivalent), 100% grant funded by the Governments of Australia, Japan and the United States.

    The Governments of the Federated States of Micronesia, Kiribati, and Nauru (the EMC Countries) have accepted funding support from the Governments of Australia, Japan and the United States (the Development Partners) to deliver the East Micronesia Cable project. The Development Partners will collaborate with the EMC Countries to ensure a fit-for-purpose submarine cable provides essential and improved telecommunications connectivity.

    Australia, via the Australian Infrastructure Financing Facility for the Pacific (AIFFP), is taking the lead role in funding and coordination arrangements. The AIFFP has contracted nem Australasia Pty Ltd as the Project Coordination Unit to support the EMC Countries facilitate management of the overall project. The Project Coordination Unit comprises a team of specialists covering technical, legal, administrative, and environmental/social requirements of the East Micronesia Cable project. The AIFFP has released the approvement for the EMCS project.

    The EMCS project was originally led by the World Bank in associate with the Asian Development Bank. The Governments of FSM and Kiribati were granted fund from the World Bank(World Bank Project Number P130592), and the Nauru Government was granted fund from the ADB (Asian Development Bank Grant Number D004-FM). Chinese HMN Technologies (HMN Tech) was in a strong position to win a bid for the $72.6 million EMCS project, offered at more than 20% below rivals including Alcatel Submarine Networks (ASN) and NEC. But the project reached a stalemate due to security concerns raised within the island nations over HMN Tech's bid. The project's planned connection to a sensitive cable leading to Guam, a U.S. territory with substantial military assets, heightened those security concerns. During the bidding process in 2020, the Government of the United States detailed its concerns in a diplomatic note sent to FSM, which has military defence arrangements with the United States under a decades-old agreement. The note said Chinese firms posed a security threat. So, the World Bank-led project declined to award a contract to HMN Tech to lay sensitive undersea communications cables after Pacific island governments heeded U.S. warnings that participation of a Chinese company posed a security threat. Finally, the World Bank-led project sank after U.S. warns against Chinese bid

    In December 2021, the Governments of Australia, Japan, the United States, the Federated States of Micronesia, the Republic of Kiribati, and the Republic of Nauru reached a six-country joint statement to improve internet connectivity in the three Pacific nations by providing funding to build the EMCS project, which builds on the strong foundations of trilateral collaboration between Australia, Japan, and the United States in the Indo-Pacific. Later in July 2022, a six-country Memorandum of Understanding was signing for the EMCS project. 

    In June 2023, Australia, Japan and the United States announced final agreement to fund the $95 million EMCS undersea cable project, supplied by Japanese NEC.

    In an announcement in September 2023, the United States announced to provide an additional $2.5 million to continue U.S. support for the East Micronesia Cable in partnership with Australia and Japan, on top of its prior $20 million commitment.

  • The Hong Kong-Guam (HK-G) cable system is a 3,700 kilometer undersea cable connecting Tseung Kwan O (TKO), Hong Kong and Piti, Guam.

    RTI (through its multiple affiliates RTI Solutions, Inc, RTI HK-G PTE. LTD., and RTI Connectivity PTE. LTD) and Google (through its indirect subsidiary GU Holding Inc) are the joint builders of the HK-G cable system.

    The HK-G cable system consists of 4 fiber pairs, with design capacity of 48 Tbps (12 Tbps per fiber pair).

    Google owns approximiately two thirds of a fiber pair on the HK-G cable system via spectrum sharing technology. RTI HK-G owns all the remaining capacity and fiber pairs. 

    RTI Connectivity controls RTI HK-G’s interests in the HK-G system through its role as Asset Manager of RTI HK-G. RTI Connectivity was appointed RTI HK-G’s Asset Manager through an Asset Management Agreement by and between the two companies.

    RTI Solutions serves as the U.S. landing party and control the Guam landing arrangements for the HK-G system under a contract with the cable landing station owner, Gateway Network Connections LLC ("GNC"), a Guam limited liability company that is 51 percent owned by Asia Connectivity Elements, Inc. (“ACE”), a Guam corporation, and 49 percent owned by TeleGuam Holdings, LLC (“GTA”). 

    RTI HK-G serves as Hong Kong landing party to land the cable at NTT's TKO Cable Landing Station and data center in Hong Kong.

    NEC was awarded the supply contract for the HK-G cable system. Furthermore, HK-G cable system utilizes capital from the Fund Corporation for the Overseas Development of Japan’s ICT and Postal Services Inc. (Japan ICT Fund), along with syndicated loans from Japanese institutions including NEC Capital Solutions Limited, etc.

    In November 2020, HK-G joint builders withdrew from the FCC the application for a license to construct, land, and operate the HK-G submarine cable system connecting the United States and Hong Kong.

  • The Hong Kong-America Cable System(HKA)is a 6-fiber-pair submarine cable connecting Hong Kong and the U.S. directly, with initial design capacity of 12.8 Tbps per fiber pair (for a total of 76.8 Tbps) using 100Gbps coherent DWDM technology.

    The HKA Consortium consists of Facebook, China Telecom, China Unicom, RTI Express, Tata Communication and Telstra. The HKA supply contract is awarded to ASN. The HKA Consortium and ASN officially announced the launch of HKA cable project at PTC 2018.

    The HKA cable system consists of a main trunk and three branching units:

    • Main Trunk, six fiber pairs connecting Chung Hom Kok in Hong Kong SAR and Hermosa Beach, China Telecom and China Unicom each owns one fiber pair, RTI, Tata and Telstra each owns a half fiber pair, Facebook owns two and half fiber pairs. 
    • Toucheng Branch, with six fiber pairs, two owned by Telstra and four owned by Facebook.
    • Manchester Branch, with two fiber pairs wholy owned Facebook.
    • Hermosa Beach Branch, with six fiber pairs, China Telecom and China Unicom each owns one fiber pair, RTI, Tata and Telstra each owns a half fiber pair, Facebook owns two and half fiber pairs.

    China Telecom controls the cable landing station in Chung Hom Kok (GB21), Telstra controls the cable landing station in Toucheng.

    Facebook is the landing party in the US, controls the Mancherster cable landing stations and the Hermosa Beach cable landing station (which is owned by RTI Infrastructure). Facebook will have exclusive control over the PFE located in RTI-I’s Hermosa Beach cable landing station, retain operational authority over the HKA landing facilities at Hermosa Beach and provide direction to RTI-I in all matters relating to the HKA system. The SLTEs for all of the HKA cable system’s fiber pairs will be installed at CoreSite’s One Wilshire and Wilshire Annex data centers in Los Angeles.

    The HKA consortium withdrew the application to the FCC for cable landing license in the United States in March 2021.

  • Honomoana is a new transpacific subsea cable connecting the United States, French Polynesia, Australia, and New Zealand, with two Australian landings in Melbourne and Sydney and a branch to Auckland, New Zealand. 

    Named after the Polynesian word for “link” (hono) and “ocean” (moana), the Honomoana cable system is part of Google's South Pacific Connect initiative which includes Honomoana and Tabua, which connects the United States and Australia to Fiji. 

    In addition to Honomoana and Tabua, the South Pacific Connect initiative will construct physically diverse cable landing stations in Fiji and French Polynesia and connect them with an interlink cable. 

    The South Pacific Connect initiative will create a ring between Australia, Fiji and French Polynesia. This ring will include pre-positioned branching units that will allow other countries and territories of Oceania to take advantage of the reliability and resilience resulting from the initiative.
