Sixteen installments mapped cables, cuts, buildings, megawatts, caches, sky, deeds, ships, sensors, and the Arctic. This one follows the ocean the internet is re-drawing right now: the Pacific, where the southern corridor is replacing the South China Sea route, the island states are getting their first fiber, and two governments are rewriting the rules for whose cables get built.
The Pacific's newest express route reached its Singapore end this summer. The Echo subsea cable, a joint project between Meta and Google, landed in Singapore on Friday, 31 July.[2] Echo will link Singapore and Jakarta to Eureka, California through a cable landing station in Guam, spanning more than 17,000 km at completion.[2] (A second source gives the main express segment as 16,051 kilometers — the two figures never merged.)[5] The system runs 12 fiber pairs on the main trunk with a design capacity of up to 260 Tbps, built by NEC on an open architecture.[3]
Echo's arrival completes one of only two dedicated express trans-Pacific fiber highways connecting the United States mainland directly to Singapore while completely bypassing the South China Sea.[3] Its sister cable Bifrost was already live: Ready for Service on October 2, 2025, a roughly 20,230 km system connecting Grover Beach, California to Singapore via the Philippines and Indonesia.[3] The two form what one industry analysis calls the foundational twin pillars of direct, ultra-low-latency trans-Pacific connectivity built for cross-border AI and cloud workloads.[3]
The route choice is the point. Historically trans-Pacific cables ran north near Japan and Taiwan before crossing the South China Sea; Echo and Bifrost establish a southern corridor that passes through Guam and Indonesian archipelagic waters, mitigating shallow-water anchor damage, seismic fault lines, and geopolitical tension zones.[3]
The economics are visible for once. An analysis of Echo's ownership stakes puts the construction cost (Capex) of a direct Singapore–U.S. fiber pair at about US$70 million, while the commercial market valuation of the same pair, sold as an indefeasible right of use, runs about US$130 million.[3] The gap is what a bundled IRU includes: when infrastructure investor Keppel monetized its five Bifrost fiber pairs, the $1.3 billion total contract value bundled 25-year operations and maintenance management, recurring fees, and landing station services.[3]
The ownership ladder is equally public. Echo was originally founded as a 50:50 joint build between Meta and Google, with both serving as sole co-applicants on the primary U.S. cable landing license.[3] The system was actually conceptualized by Trans Pacific Networks (TPN), which announced it at the 2019 Indo-Pacific Business Forum in Bangkok before Google and Meta came on as partners.[3] TPN holds three fiber pairs and its expansion is backed by debt financing from the U.S. International Development Finance Corporation — a DFC loan of up to $190,000,000.[3] Legacy carrier FLAG invested $70 million to acquire one full fiber pair on Echo directly from Google.[3]
Echo is one strand of a wider Pacific weave. TPN also participates in Tabua, a new transpacific cable connecting the U.S. to Australia and Fiji under Google's South Pacific Connect initiative, with 16 fiber pairs on its trunk and a total system capacity of 272 Tb/s.[5] It has access to Topaz, the system connecting Japan, Canada, and the U.S. mainland.[5]
The small-island layer is where the change is most basic. On May 15, 2026, NEC completed construction of the East Micronesia Cable System (EMCS), a roughly 2,250 km cable connecting the Federated States of Micronesia, Kiribati, and Nauru — the first optical submarine cable connecting the state of Kosrae, Tarawa in Kiribati, and Nauru, which previously relied on satellite communications.[1] The project was grant-funded by the governments of Australia, Japan, and the United States.[1] For Nauru it is the first undersea cable in the country's history.[1]
While companies lay cable, Washington is reshaping the licensing layer. On June 25, 2026 the FCC adopted new rules that presumptively exempt cable applications from the Team Telecom security review when licensees certify to high security standards, and introduced a licensing requirement for owners and operators of submarine line terminal equipment (SLTE) — the gear connecting cable systems to U.S. terrestrial facilities.[7] The agency called the rulemaking the first comprehensive update to its cable rules in 25 years.[7]
Two weeks ago the U.S. Trade and Development Agency funded a feasibility study for a Thailand–U.S. cable, the Thailand-US Submarine Cable System (THUS), an 11,500-mile route connecting Thailand to the U.S. via Indonesia, Malaysia, the Philippines, Singapore, and Vietnam — a quoted goal of avoiding the South China Sea and other routes that carry security risks.[6][4] The project is designed to replace Thailand's aging subsea connection; the Asia-America Gateway, dating to 2009, is currently the only subsea system linking Thailand to the U.S.[6] The feasibility study will be conducted by Florida-based APTelecom for Thailand's state-owned National Telecom.[6] A government statement sees the payoff as secure fiber for a regional market of more than 600 million people.[6]
The scale of the build is large. Nearly two dozen international cables are expected to be built across the Pacific between 2022 and 2030, per the International Institute for Strategic Studies, and other estimates put the aggregate cost of new undersea cable construction above $14 billion between 2025 and 2027.[4]
The deeper frame is strategic. Channels News Asia's review of the subsea contest notes the cables carry about 98 per cent of the world's data traffic and are now, as an ASPI analyst puts it, "indispensable strategic" assets at the heart of the U.S.-China contest for digital dominance.[8] A flagship example is SeaMeWe-6, a planned 21,700 km system linking Singapore and France, initially expected to be built by China's HMN Tech before the contract went to U.S.-based SubCom after a U.S. lobbying campaign.[8] Beijing has kept expanding through HMN Tech and Digital Silk Road-linked projects; a CAICT report said HMN Tech had delivered more than 100,000 kilometers of submarine cable systems with operations spanning more than 70 countries and regions.[8]
A September 22, 2026 report from the U.S.-China Economic and Security Review Commission argues the threat is structural, not commercial: it finds China is developing capabilities to achieve "Command of the Deep Sea," with the potential to cause major disruption across these networks, and it builds a Trans-Pacific Cable Gray Zone Vulnerability Index to rank which U.S. trans-Pacific systems are most exposed to gray-zone sabotage.[9] Commission Chair Randy Schriver framed the stakes plainly: undersea cables are the backbone of the global digital economy and increasingly a matter of national security.[9]
