Key takeaways
- Meta plans Petal, a roughly 7,000 kilometer France–U.S. subsea cable targeted for 2029 with 1 petabit per second of capacity—twice today’s leading transoceanic systems, according to Meta.
- Petal is part of Meta’s wider effort to secure high capacity international infrastructure for AI services, alongside the 50,000 kilometer plus Project Waterworth.
- Reports of camera free “Luna” AI glasses remain unconfirmed, but they point to the other end of Meta’s AI strategy: voice first consumer access to Meta AI.

Meta’s planned Petal subsea cable is more than a transatlantic connectivity upgrade. It is a bid to control a larger share of the network infrastructure needed to run AI services at global scale.
The project is designed to connect France and the United States across roughly 7,000 kilometers and enter service in 2029. Meta says Petal will deliver 1 petabit per second (Pbps) of capacity—equivalent to 1,000 terabits per second—and carry twice the capacity of today’s best-in-class transoceanic cables without a proportional increase in power use or physical infrastructure. 17

Petal: a 1-Pbps transatlantic cable planned for 2029
Meta is developing Petal with NEC and Sumitomo Electric Industries; Orange will support the French landing and connection to terrestrial networks. 17
26
28
The company describes Petal as the first subsea system designed to provide petabit capacity at transoceanic distances and the first to deploy multi-core fiber at scale. The design uses two-core fiber—two optical transmission paths within one fiber—along with repeater technology intended to reduce power consumption. 26
28
That distinction matters because undersea systems have practical constraints beyond raw bandwidth: cable size, power delivery, repeater design, route engineering, and the cost and complexity of landing infrastructure all shape what can be deployed. Meta’s claim is that multi-core fiber can substantially raise capacity per fiber without requiring a matching expansion of the wider system. 17
28
However, Petal is still a planned system. The 1-Pbps figure, the claimed twofold improvement, and the efficiency benefits are design targets stated by Meta and its partners—not yet independently verified operational results. 17

Why Meta wants more control of long-haul capacity
AI services depend on far more than a model running in one data center. They require reliable links among data centers, regions, content-delivery infrastructure, and the people using apps and devices around the world.
Petal gives Meta a dedicated high-capacity route across the Atlantic, while potentially reducing its dependence on capacity purchased from third-party network operators. Meta has explicitly framed its subsea investments around the need for greater capacity, resilience, and global reach as AI use expands. 13
17
For a company operating Facebook, Instagram, WhatsApp, and Meta AI services, that kind of infrastructure can support the movement of data and computing workloads between regions. The strategic significance is not simply a faster consumer internet connection; it is the ability to build and manage more of the transport layer beneath a global AI platform.
Petal alongside Project Waterworth
Petal is a focused France–U.S. system. Project Waterworth is Meta’s much broader connectivity initiative.
Meta announced Waterworth in February 2025 as a multi-year subsea project spanning more than 50,000 kilometers and reaching five continents. Meta says the project will connect the U.S., India, Brazil, South Africa, and other regions through three new oceanic corridors. 13
| Project | Planned scope | Stated role |
|---|---|---|
| Petal | About 7,000 km between France and the U.S.; targeted for 2029 | A petabit-class transatlantic route using multi-core fiber. |
| Project Waterworth | More than 50,000 km across five continents | A broader global connectivity buildout intended to increase capacity, reliability, and geographic reach. |
The projects operate at different scales but serve a related goal: expanding the infrastructure under Meta’s international products and AI ambitions. Waterworth is the global network footprint; Petal is a high-capacity technology and route-specific bet across the Atlantic.
Reports also describe an Aurora cable between New Jersey and Denmark, but the available sourcing provides limited detail on its project status and technical role. It should not be treated as interchangeable with Petal or Waterworth. 1
The consumer end of the strategy: reported Luna AI glasses
The infrastructure story coincides with reports that Meta could use its September 23–24 Connect conference to show a camera-free smart-glasses model internally codenamed Luna. Meta had not confirmed the product details in the available reporting. 34
37
Reports describe Luna as a voice-first device with six microphones, speakers, and a button for invoking Meta AI. The same reports say it could support Meta’s reported Muse consumer AI agent and could ship as soon as October. 33

If accurate, the device would represent a different layer of the same broad strategy:
- Subsea cables and data centers provide the capacity and reach for AI services.
- Meta AI and Muse would provide the assistant layer.
- Glasses could provide an always-available, hands-free interface.
Removing a camera would eliminate the specific risk of discreet visual recording and concerns about an obscured or disabled recording-status light. It would not settle all privacy questions, however. A microphone-based wearable would still require clear safeguards and disclosures around consent, audio capture, processing, retention, and any cloud transmission.
Why the September 2026 calendar is notable
Meta Connect overlaps with Qualcomm’s Snapdragon Summit in Maui, scheduled for September 22–24. Qualcomm’s official agenda includes sessions on personal AI, sound, XR and wearables, as well as AI computing—areas closely related to the chips and software required for voice-driven devices and on-device AI. 54
61
The same period also includes a planned Trump–Xi meeting, where AI is among the issues expected to be discussed. Politico reported that OpenAI CEO Sam Altman, Nvidia CEO Jensen Huang, and Qualcomm CEO Cristiano Amon planned to attend an associated state dinner. 50
57
These events concern different parts of the technology stack, but together they show where AI competition is concentrating: network capacity, semiconductors, consumer devices, software platforms, and policy governing cross-border technology.
The bottom line
Petal is Meta’s clearest near-term example of an AI infrastructure strategy reaching below the data center and into the ocean. If it enters service as planned in 2029, the cable would add a dedicated, petabit-class U.S.–France route built around a new fiber architecture. 17
26
28
Combined with Waterworth’s global footprint and the reported push toward voice-first AI glasses, Meta appears to be investing across the full path from international network capacity to the consumer interface. The central uncertainty is execution: Petal’s most consequential technical claims will only be testable once the system is deployed and operating at scale.
