Almost everything the world says to itself across an ocean travels not by satellite but by glass — fibre-optic cables no thicker than a garden hose, lying on seabeds in the dark, carrying well over ninety-five per cent of intercontinental data on the TeleGeography-derived estimates the industry itself uses. This guide maps the twenty companies that matter most to that hidden system: who builds the cables, who owns them, who leads each house in October 2026, which ships lay and repair them, which named systems they built or own, and what each publishes — dated and sourced — about its scale.
The distinction that organises the guide is the one the industry lives by. Eight manufacturers and installers — SubCom, Alcatel Submarine Networks, NEC, HMN Technologies, Prysmian, Nexans, Global Marine Group and Orange Marine — make cable, repeaters and ships' work possible; eight owner-operators — Telxius, PCCW Global, Tata Communications, Southern Cross, Aqua Comms, EllaLink, Seaborn and Gulf Bridge International — own systems and sell the capacity on them; and four hyperscaler owners — Meta, Google, Microsoft and Amazon — now fund and own systems outright, framed here explicitly as owners and consortium leads, never as manufacturers. Every kilometre named in the hyperscaler entries was made and laid by a company in the first group.
MANUFACTURERS & INSTALLERS
1. SUBCOM — EATONTOWN, UNITED STATES
Founded 1955 (entry into submarine communications; industrial origins in the mid-1800s) · Manufacturer & installer
Leader: David Coughlan, Chief Executive Officer (named CEO at the Cerberus closing in 2018; quoted as CEO in SubCom's 15 May 2025 one-million-kilometre release) Chair: Not published — no chairman title is published on SubCom's official site in sources consulted, Oct 2026
Leadership: David Coughlan, CEO, is the named executive in SubCom's official releases (2025); divisional and marine-operations leadership is published project by project, not as a single roster — stated plainly

Website: subcom.com · Contact: Phone: Not published; Email: Not published; Via subcom.com contact form and published project / careers pages; no published general email or switchboard in sources consulted
Founded as a submarine-communications business in 1955 from 19th-century American cable manufacture; passed through Tyco and TE Connectivity as TE SubCom before Cerberus Capital Management acquired it in 2018 and restored the SubCom name. In May 2025 it became the first supplier to deploy more than one million kilometres of subsea cable. SubCom controls the process from cable manufacture in New Hampshire to installation and maintenance, which is why governments as well as hyperscalers appear in its order book. Its Cable Security Fleet role gives a commercial builder a formal national-security function no rival in this guide replicates in the United States.

Founded 1858 · Manufacturer & installer
Leader: Alain Biston, President and Chief Executive Officer (in the role through the Nokia-to-French-State sale; quoted as President and CEO in Nokia's June 2024 sale announcement) Chair: Not published separately — chairmanship arrangements under APE ownership are not published as a single named title in sources consulted, Oct 2026
Leadership: Alain Biston, President and CEO, is the named executive in official sale and project releases; site leadership at Calais, Les Ulis, Greenwich (UK) and Trondheim-area operations in Norway is published locally, not as a global roster — stated plainly
Business: Turnkey submarine transmission systems: cable, repeaters and branching units, terminal equipment, project management, marine installation and maintenance, for telecom, content-provider and energy customers
Customers: Carriers, content and cloud providers and energy operators worldwide, as published in ASN's own system announcements — including Southern Cross (Tasman Express supply contract, June 2025) and EllaLink (Mauritania branch, 2025)
Scale: Turnover of more than €1 billion and about 2,400 employees at four European sites (French State acquisition release, 7 Nov 2024); more than 750,000 km of optical submarine cable deployed worldwide (Nokia / ASN, 2024)
Ships & systems: Ships: Fleet of seven laying and maintenance vessels (French State release, Nov 2024), managed with Louis Dreyfus Armateurs — the fleet includes Île de Bréhat, Île de Batz, Île de Sein, Île d'Yeu, Île d'Aix, Île de Ré and Peter Faber, as named in ASN fleet publications Systems: More than 750,000 km deployed in total (2024). Named recent systems: EllaLink (Brazil–Portugal, supplier), Southern Cross Tasman Express (supply contract signed June 2025, for 2028), Tikal supply for Telxius (with Cancún branch option, 2026 reporting) and the Mauritania branch of EllaLink (2025–27)

Founded in 1858 and built through the Alcatel, Alcatel-Lucent and Nokia successions; Nokia agreed in June 2024 to sell 80% to the French State (Agence des participations de l'État, APE), retaining 20% for a transition period, and the sale completed at the end of 2024 / early 2025 reporting. ASN is Europe's only turnkey submarine cable maker of world scale. ASN's change of owner is the guide's clearest example of a state treating a cable builder as strategic infrastructure: Paris bought control not of a network, but of the factory, the repeaters and the ships that make networks possible.

Scale: Division revenue not published separately by NEC. Scale as published: cumulative installation record exceeding 400,000 km — about ten times around the Earth (NEC release, May 2026); NEC Group revenue is published at group level in NEC's annual report and is not the submarine division's revenue — not carried here as division scale
Ships & systems: Ships: No owned cable fleet published — NEC charters vessels per project and, in October 2022, signed its first long-term charter, for about four years, with Global Marine Systems for a dedicated optical cable-laying ship (CS Recorder, named in the charter reporting) Systems: East Micronesia Cable System (EMCS, about 2,250 km, completed 2026); Kochi–Lakshadweep Islands system (about 1,870 km, for BSNL); Chennai–Andaman & Nicobar system (completed Dec 2020); and, across six decades, systems totalling more than 400,000 km (NEC, 2026)
Footprint: Headquarters Tokyo, Japan; cable plant at OCC in Yokohama; repeater manufacture in Japan; project delivery concentrated in Asia-Pacific with systems worldwide Headquarters address: 7-1, Shiba 5-chome, Minato-ku, Tokyo 108-8001, Japan (NEC Corporation published head office)
Structure: Division of NEC Corporation, listed on the Tokyo Stock Exchange (6701); cable manufacture by OCC Corporation and repeaters by NEC Platforms, Ltd., both NEC group companies
Website: nec.com/en/global/solutions/submarine-cable · Contact: Phone: Not published for the submarine division; Email: Not published for the submarine division; Via nec.com submarine-cable solution pages and NEC country offices; no published division email or phone
NEC, founded in Tokyo in 1899, has supplied submarine cable systems for over 60 years — cable made by its subsidiary OCC Corporation and repeaters by NEC Platforms — acting as system integrator for surveys, route design, manufacture, laying and acceptance testing, with a cumulative installation record above 400,000 km by 2026. NEC's 2022 decision to charter a ship long-term for the first time, rather than hire one project by project, is the division's own admission that vessel scarcity — not electronics — is now the industry's binding constraint.

Business: Turnkey submarine network solutions: system design, permitting support, marine survey, cable / repeater / branching-unit manufacture, integration, marine installation, commissioning, maintenance and upgrades
Customers: Telecom carriers and consortium owners, oil and gas operators and governments as published — consortium customers include Singtel and the Asia Link Cable partners, the PEACE cable owners and the SeaMeWe-6 consortium (HMN Tech as supplier on published segments)
Scale: Revenue not published (unlisted subsidiary; Hengtong publishes group results, which are not HMN Tech's revenue and are not carried here). Scale as published: turnkey systems delivered across Asia, Africa, the Americas and Europe since 2008, including the systems named below — HMN Tech publishes project totals, not a cumulative kilometre figure in sources consulted, and none is estimated here
Ships & systems: Ships: No owned installation fleet is published — HMN Tech delivers marine installation with chartered and partner vessels project by project; its former joint-venture partner Global Marine supplied the original marine capability (see Global Marine Group entry) Systems: Asia Link Cable (ALC, about 9,979 km design, consortium system for which HMN Tech is turnkey supplier); Asia Direct Cable (ADC); PEACE (Pakistan & East Africa Connecting Europe); SeaMeWe-6 supplier role on published segments; WACS and other Huawei Marine-era systems carried in the company's project history
Footprint: Headquarters and manufacture in Tianjin, China, with research and development in Beijing and a United Kingdom office at Liverpool serving EMEA and the Americas (company listings consulted) Headquarters address: No. 2 Lanyuan Road, Huayuan New Technology Industrial Park, Tianjin, China — as published in company listings consulted; HMN Tech's own site routes contact through its web form
Structure: Subsidiary of Hengtong Optic-Electric Co., Ltd. (listed in Shanghai), which acquired Huawei's stake in Huawei Marine Networks in 2019–20; originally a Huawei / Global Marine joint venture (2008)
Website: hmn-tech.com · Contact: Phone: Not published; Email: Not published; Via hmn-tech.com contact form; no published general email or phone in sources consulted
Established in late 2008 in Tianjin as Huawei Marine Networks, a joint venture of Huawei Technologies and Global Marine Systems; Huawei's majority stake was acquired by Hengtong Optic-Electric in 2019–20 and the business renamed HMN Technologies (HMN Tech), keeping its Tianjin manufacture, its UK presence and its turnkey delivery model. Geopolitics follows HMN Tech into every tender: systems it supplies are routinely examined by landing-country governments, which makes its published consortium wins — Singtel-led ALC among them — the more significant as evidence of where it can still build.

Leader: Massimo Battaini, Chief Executive Officer (Group CEO since 2024; quoted as CEO in Prysmian's 2025 and 2026 results releases) Chair: Francesco Gori, Chairman of the Board — as published in Prysmian's board listings consulted, Oct 2026
Leadership: Massimo Battaini (CEO); Pier Francesco Facchini (CFO); Cristina Bifulco (Chief Strategy, IR, M&A & Communication Officer); Hakan Ozmen, Executive Vice President, Projects / Transmission business, quoted in fleet-expansion releases
Business: Transmission (high-voltage submarine and land power systems, turnkey), Power Grid, Digital Solutions (fibre and telecom cables) and Industrial & Construction / Specialties — submarine work is overwhelmingly power transmission, with fibre-optic elements inside power systems and a separate digital-solutions fibre business
Customers: Transmission system operators (TenneT, RTE, National Grid and Terna among published customers), offshore-wind developers, utilities and — in Digital Solutions — carriers and hyperscalers, with major hyperscaler agreements reported as nearing signature in May 2026

Built from Pirelli's cable business, independent since 2005 and enlarged by Draka (2011), General Cable (2018) and Encore Wire (2024). In submarine work Prysmian is principally a power-cable maker — interconnectors and offshore-wind export cables — with a growing digital / fibre business; its telecom submarine context is carried here on that honest basis, not as a transoceanic telecom turnkey rival to SubCom or ASN. Prysmian and Nexans between them dominate submarine power. Their presence in a telecommunications guide is deliberate and labelled: modern power interconnectors carry fibre, their fleets compete for the same yards and crews, and their order books are the energy half of the undersea story.

6. NEXANS — PARIS (LA DÉFENSE, COURBEVOIE), FRANCE
Founded 1897 (origins in Câbles de Lyon); Nexans created from Alcatel's cable business in 2000–01 · Manufacturer & installer
Leader: Julien Hueber, Chief Executive Officer (appointed by the Board on 13 October 2025, effective immediately, succeeding Christopher Guérin after seven years — Nexans announcement, 13 Oct 2025) Chair: Jean Mouton, Chairman of the Board of Directors (quoted in Nexans' CEO appointment announcement, 13 Oct 2025)
Leadership: Julien Hueber (CEO, from Oct 2025); Jean Mouton (Chairman); Pascal Radue (Senior EVP, PWR Transmission, 2026) — with the balance of the Executive Committee as published on nexans.com
Business: PWR Transmission (high-voltage subsea and land power systems, turnkey EPCI), PWR Grid and PWR Connect — subsea work is power transmission: interconnectors, offshore-wind export systems and the Halden-made HVDC/HVAC cables that serve them
Customers: Transmission system operators and developers as published — TenneT (LanWin2 / BalWin3 525 kV frame programme, 2026), RTE (€1 billion offshore-wind frame agreement reported 2025), Statnett, Terna and Red Eléctrica
Scale: €6.1 billion standard sales in 2025, €728 million adjusted EBITDA and €344 million free cash flow (Nexans investors page, 2025 key figures, Oct 2026); 12,830 people in 39 countries (Nexans, 2026 releases); PWR Transmission adjusted backlog of €7.9 billion recorded at September 2025 in market reporting of Nexans results

Created from the cable activities of Alcatel in 2000–01 and refocused since 2018 as a pure player in electrification. Its subsea context — like Prysmian's — is power: high-voltage submarine interconnectors and offshore-wind connections made at Halden, Norway, and laid by its own fleet; it is not a transoceanic telecom-system supplier, and is included on that stated basis. Nexans' October 2025 change of chief executive — a 23-year insider, Julien Hueber, replacing Christopher Guérin — was framed by its chairman as acceleration, not correction: the backlog, at €7.9 billion for transmission alone, explains why.

7. GLOBAL MARINE GROUP (GLOBAL MARINE SYSTEMS) — CHELMSFORD (ESSEX), UNITED KINGDOM
Founded 1850s (marine-installation lineage from the first Channel cables); Global Marine Systems in its modern form from the 1990s · Manufacturer & installer
Leader: Bruce Neilson-Watts, Chief Executive Officer — the title and name as published in NEC's October 2022 charter release (HQ: Essex, UK, CEO: Bruce Neilson-Watts); a post-Keppel permanent CEO roster is not published in official sources consulted, Oct 2026 — a named gap Chair: Not published in sources consulted, Oct 2026
Leadership: Bruce Neilson-Watts is the named CEO in the official releases consulted; Global Marine publishes vessel and depot leadership operationally rather than a corporate C-suite — stated plainly
Business: Submarine cable installation, maintenance and repair (telecoms principally; also power, oil & gas and deep-sea research support); cable depots, jointing and burial, and long-term maintenance-zone contracts
Customers: Cable owners and system suppliers as published — NEC (long-term charter, 2022), maintenance-zone consortia in the Atlantic, Pacific and Indian Oceans, and telecom and energy customers of its installation fleet
Scale: Revenue not published (private company). Scale as published: a fleet of six vessels in July 2026 reporting (C.S. Clipper, C.S. Recorder, Cable Innovator, Cable Retriever, C.S. Sovereign and Wave Sentinel), plus subsea trenching vehicles, and a new maintenance vessel on order for Q4 2029 (Data Center Dynamics, Jul 2026, reporting Global Marine's own announcement)
Ships & systems: Ships: C.S. Sovereign; C.S. Recorder; C.S. Clipper (ex-Normand Clipper, acquired after charter since 2021); Cable Innovator; Cable Retriever; Wave Sentinel; Atlantic Guardian is also listed in fleet summaries consulted — vessel counts vary by source and date (six in Jul 2026 reporting, seven in 2026 fleet listings) and both are carried with their labels; newbuild maintenance ship due Q4 2029 Systems: Not a system owner — Global Marine installs and maintains other owners' systems, including NEC-charter installations and maintenance-zone systems across the Atlantic, Pacific and Indian Oceans; it publishes contracts, not a system portfolio
Footprint: Headquarters in Essex, United Kingdom; cable depots at Portland (UK), Victoria (Canada), Bermuda and Subic Bay (Philippines) in published depot listings; worldwide maintenance zones Headquarters address: Ocean House, Chelmsford, Essex, United Kingdom — as published in company listings consulted; the group's own site routes contact through its web form, so the address is carried with that label

Website: globalmarine.group · Contact: Phone: Not published; Email: Not published; Via globalmarine.group contact form; no published general email or phone in sources consulted
Descends from the companies that laid and maintained cables from the 1850s onward; was the marine partner in the original Huawei Marine joint venture (2008) and a long-time NEC charter partner. J.F. Lehman & Company sold Global Marine to Keppel's infrastructure fund in March 2025, and in July 2026 the group ordered a purpose-built cable-maintenance ship from Colombo Dockyard for delivery in the fourth quarter of 2029 — the first stage of a phased fleet renewal. The industry's repair problem is Global Marine's order book: with only about 60 cable ships afloat worldwide and much of the maintenance fleet nearing retirement, its 2029 newbuild — ordered under state-linked Singaporean ownership — is a strategic, not merely commercial, decision.

The cable-ship arm of the Orange group, based at La Seyne-sur-Mer, operating installation and maintenance ships for Orange and for third-party owners, together with its Italian subsidiary Elettra Tlc. Its 2023 ship Sophie Germain began a fleet renewal that continued in November 2025 with an order for two sister ships from Colombo Dockyard, for delivery in 2028 and 2029. Orange's 2025 order for two more repair ships, explicitly to replace vessels built in 1983 and 1987, is the clearest published evidence in this guide of the world fleet's age problem — and of who intends to profit from solving it.

India's former international monopoly carrier VSNL, acquired by the Tata group in 2002 and renamed Tata Communications in 2008 after absorbing Tyco Global Network — the purchase that made it, on its own published description, the owner of the world's largest wholly owned subsea fibre backbone. In 2025 it integrated the new TGN-IA2 system and in July 2026 announced further India–Singapore subsea investments. Tata's July 2026 India–Singapore investments — capacity bought, not just built, including a system not due until 2029 — show the owner-operator model adapting to the hyperscaler era: secure the fibre pair first, argue about construction later.

Scale: Revenue not published (private company). Scale as published: the GBI system was built as a Gulf ring with at least 5.18 Tbit/s of capacity on its ready-for-service announcement, with historical investment of US$445 million reported at its Iraq landing; the 2025 Nokia programme is designed to let GBI deliver more than 50 Tbit/s to customers (Nokia, 22 Oct 2025)

Founded in 2008 as the Middle East's first privately owned, carrier-neutral submarine cable operator, building a self-healing Gulf ring connecting Qatar, the UAE, Iraq, Kuwait, Bahrain, Oman and Saudi Arabia, with onward links to India and Europe. In October 2025 GBI selected Nokia's 1830 GX platform for a new high-capacity terrestrial route through Iraq, designed also for subsea backhauling, offering more than 50 Tbit/s to its customers. GBI's 2025 turn to a terrestrial route through Iraq — explicitly as diversity from subsea corridors — mirrors the Red Sea lesson the whole industry learned in 2024–25: a second path that never touches the water can be worth more than a third cable in it.

Leadership: Parent leadership as above; no separate subsea-cable executive roster is published by Meta — its cable announcements are issued by its engineering / infrastructure organisation without a named cable chief in sources consulted, a named gap
Business: As a cable owner: sole-owner systems, consortium leadership and capacity ownership to connect Meta's data centres and serve Facebook, Instagram, WhatsApp and its AI infrastructure. Meta's businesses themselves (advertising, apps, Reality Labs) are outside this guide's scope
Customers: Not a seller of cable capacity as a business line — Meta's systems serve its own platforms and, on consortium systems such as 2Africa, its co-investors' customers; capacity partners on 2Africa include Vodafone, China Mobile, Orange and other carriers named in the consortium's releases
Scale: Parent revenue is NOT Meta's cable business and is not carried here as scale. Cable posture as published / reported: 2Africa — 45,000 km, 180 Tbit/s, 46 landings in 33 countries, core completed Nov 2025 (Meta / consortium reporting); Project Waterworth — about 50,000 km, five continents, 24 fibre pairs, reported as a programme of more than US$10 billion in press reporting of Meta's Feb 2025 announcement — the dollar figure is carried as reported, not as a Meta-published audited figure

Meta is included solely as an owner and consortium lead of submarine systems, not as a manufacturer or installer — it builds no cable and operates no ships. From MAREA (with Microsoft, 2016–17) and the 45,000 km 2Africa consortium system (core completed Nov 2025) to the wholly Meta-led Project Waterworth (announced Feb 2025), Meta has become one of the largest private investors in subsea infrastructure in the world. Meta's framing in this guide is explicit and limiting: an owner, not a builder. Every kilometre named here was manufactured and laid by companies elsewhere in these pages.

Customers: Not a seller of cable systems — Google's cables serve its own services and cloud customers indirectly; consortium systems carry co-investors including Meta (Echo, Apricot) and carriers named system by system in TeleGeography's catalogue
Scale: Parent revenue is NOT Google's cable business and is not carried here as scale. Cable posture as published: sole-owner systems including Dunant (about 6,400 km, 250 Tbit/s-class on Google's published description at service), Grace Hopper, Equiano (about 15,000 km, 144 Tbit/s on published descriptions), Curie, Firmina, Topaz, Nuvem and Sol, plus part-ownership of 30+ systems in total (TeleGeography catalogue, updated Sep 2026); individual programme costs are published system by system (Equiano reported at about US$1 billion in industry reporting) and are not aggregated here
Ships & systems: Ships: Not applicable — owns systems and capacity, operates no cable fleet; its systems are built and laid by SubCom, ASN, NEC and other builders in this guide (Dunant by SubCom on published project reporting) Systems: Sole owner (TeleGeography, Sep 2026): Dunant, Grace Hopper, Equiano, Curie, Firmina, Topaz, Nuvem, Sol, Junior, Monet-era and Pacific systems including Honomoana, Tabua, TPU and Umoja; part owner: FASTER, Unity, Echo, Apricot, PLCN, SJC / SJC2, INDIGO, JGA-S, Havfrue and others — the full dated list is TeleGeography's catalogue cited here
Footprint: Headquarters Mountain View, California (the Googleplex); cable landings and cloud regions on six continents Headquarters address: 1600 Amphitheatre Parkway, Mountain View, CA 94043, United States (published head office)

Google is included solely as an owner of submarine systems, not as a manufacturer or installer. It moved from consortium shares (Unity, FASTER) to wholly owned private cables — Curie (2019), Dunant (2021), Grace Hopper and Equiano — and by TeleGeography's September 2026 catalogue held interests in more than thirty systems, the widest portfolio of any content provider. Google's sole-owner model changed the industry's economics: a private cable needs no consortium meetings, which is why Google's systems are named for scientists and explorers and announced like products.

19. MICROSOFT — SUBSEA CABLE PROGRAMMES — REDMOND, WASHINGTON, UNITED STATES
Founded 1975 (Microsoft, in Albuquerque, New Mexico) · Hyperscaler owner
Leader: Satya Nadella, Chairman and Chief Executive Officer, Microsoft Corporation (CEO since Feb 2014, Chairman since 2021; in both roles in 2025–26 listings) Chair: Satya Nadella, Chairman (see CEO field — the roles are combined)
Leadership: Satya Nadella (Chairman and CEO); Brad Smith (Vice Chair and President); Amy Hood (EVP and CFO) — parent leadership as published, Oct 2026
Business: As a cable owner: part-ownership, fibre-pair ownership and major capacity purchases connecting Azure cloud regions; plus strategic investments in cable operators. Microsoft's software and cloud businesses are outside this guide's scope
Customers: Not a seller of cable systems — capacity serves Azure and Microsoft's own services; consortium partners include Meta (MAREA, Amitié), Amazon (MAREA capacity / Amitié context) and carriers named in TeleGeography's catalogue
Scale: Parent revenue is NOT Microsoft's cable business and is not carried here as scale. Cable posture as published: part owner of MAREA, Amitié, AUG East, Beaufort, JAKO and SeaMeWe-6, major capacity buyer on AEC-1 and EXA Express, and part owner of I-2SEA and the New Cross Pacific system — and no sole-owner system (TeleGeography catalogue, updated Sep 2026, which is the basis for the distinction drawn here)
Ships & systems: Ships: Not applicable — owns capacity and consortium shares, operates no cable fleet; its systems are built by the manufacturers in this guide (MAREA was built by SubCom on published project history) Systems: MAREA (Virginia Beach–Bilbao, part owner with Meta; Telxius operates the system); Amitié (part owner, transatlantic); New Cross Pacific (part owner); SeaMeWe-6 (part owner); I-2SEA (part owner, India–Malaysia–Singapore, for the late 2020s on published reporting); AEC-1 and EXA Express as major capacity buyer (TeleGeography, Sep 2026)
Footprint: Headquarters Redmond, Washington; Azure regions and cable landings worldwide through the systems above, including reported Ireland–Wales system filings in industry coverage Headquarters address: One Microsoft Way, Redmond, WA 98052, United States (published head office)

Microsoft is included solely as an owner and capacity buyer, not as a manufacturer or installer — and, alone among the four hyperscalers here, it holds no solely owned cable on TeleGeography's September 2026 catalogue. Its model is partnership: MAREA with Meta (2016–17), Amitié, fibre-pair purchases, and investments in operators including Aqua Comms (2015 context), continued in the Lightstorm-led I-2SEA consortium for service in the late 2020s on published reporting. Judged by cables alone, Microsoft looks like the cautious hyperscaler. Judged by the cloud regions those cables feed, the caution is the point: it rents certainty from several owners rather than concentrating it in one hull.

20. AMAZON (AWS) — SUBSEA CABLE PROGRAMMES — SEATTLE, WASHINGTON, UNITED STATES
Founded 1994 (Amazon, in Bellevue, Washington) · Hyperscaler owner
Leader: Andy Jassy, President and Chief Executive Officer, Amazon.com, Inc. (CEO since Jul 2021; the 'President and CEO' title is Amazon's published form) Chair: Jeff Bezos, Executive Chair, Amazon.com, Inc. (founder; Executive Chair since 2021)
Leadership: Andy Jassy (President and CEO); Jeff Bezos (Executive Chair); Brian Olsavsky (SVP and CFO); Matt Garman (CEO, AWS) — parent leadership as published, Oct 2026
Business: As a cable owner: sole-owner systems (from Fastnet), consortium shares and major capacity purchases connecting AWS cloud regions. Amazon's retail, media and device businesses are outside this guide's scope
Customers: Not a seller of cable systems — capacity serves AWS and Amazon's own services; consortium partners include Meta, Google, Microsoft and carriers named system by system in TeleGeography's catalogue
Scale: Parent revenue is NOT Amazon's cable business and is not carried here as scale. Cable posture as published: Fastnet (sole owner, Maryland–County Cork, more than 320 Tbit/s, announced Nov 2025, for readiness for service in 2028 on published reporting); part owner of AUG East, Beaufort, JAKO and JUPITER; major capacity buyer on Havfrue and MAREA (TeleGeography catalogue, updated Sep 2026)
Ships & systems: Ships: Not applicable — owns systems and capacity, operates no cable fleet; Fastnet's builder is a matter of AWS's project announcements as published, and marine work will be contracted from the builders in this guide Systems: Fastnet (sole owner, United States–Ireland, announced Nov 2025, RFS 2028); Sta'O'Nuk (sole owner, on TeleGeography's catalogue); JUPITER (part owner, transpacific); Havfrue / AEC-2 and MAREA (major capacity buyer); AUG East, Beaufort and JAKO (part owner) — TeleGeography, Sep 2026
Footprint: Headquarters Seattle, Washington, with a second headquarters campus in Arlington, Virginia; AWS regions and cable landings worldwide through the systems above Headquarters address: 410 Terry Avenue North, Seattle, WA 98109, United States (published head office)
Structure: Amazon.com, Inc., listed on Nasdaq (AMZN); Jeff Bezos, founder and Executive Chair, is its largest shareholder (about 8.2% on an Aug 2026 SEC filing summary)
Website: aws.amazon.com · Contact: Phone: Not published; Email: Not published; Via aws.amazon.com and AWS sales routes; no cable-programme contact is published
Amazon is included solely as an owner and capacity buyer, not as a manufacturer or installer. Through Amazon Web Services it took consortium shares and major capacity positions for a decade — JUPITER, Havfrue and a MAREA capacity position among them — before announcing Fastnet in November 2025, its first solely owned submarine cable, linking Maryland in the United States with County Cork, Ireland, for service in 2028. Fastnet closes the hyperscaler set: after November 2025 every one of the four American cloud giants either owns, part-owns or is building a transoceanic system in its own name — the fact this whole section of the guide exists to record.

NAMED GAPS
Aqua Comms publishes no permanent CEO in official sources consulted for this edition — Jim Fagan left in 2024, Andy Hudson was appointed acting CEO, and no permanent successor is named; the entry says so rather than carrying an older name as current. Global Marine Group's post-Keppel (March 2025) permanent CEO roster is likewise not published in official sources consulted; Bruce Neilson-Watts is carried with his October 2022 NEC-release attribution and date. HMN Technologies publishes no full official executive roster in English — its CEO, COO and CTO are carried from the consortium releases and listings consulted, labelled as such, and its revenue, like SubCom's, Telxius's, Southern Cross's, Aqua Comms', EllaLink's, Seaborn's and GBI's, is not published (private companies). NEC, PCCW Global and Prysmian / Nexans segment figures are handled the same way: a parent or group figure is never presented as a cable division's revenue, and the hyperscaler entries carry no parent revenue as scale at all — only dated cable programme figures. Tata Communications' chairman and CFO and Nexans' CFO are not carried without a current official listing. Published general emails exist for only a minority of the twenty — most of this industry routes contact through web forms and sales teams, and this guide prints the route. Vessel counts for Global Marine vary by source and date (six in July 2026 reporting, seven in 2026 fleet listings); both are carried with their labels. Orange Marine's Didier Dillard is styled CEO in earlier Orange releases and President in November 2025; both titles are carried with their dates.
