Inside Petal: Building the World’s First Petabit-Class Transoceanic Subsea Cable
Meta is developing Petal, the first transoceanic subsea cable with petabit capacity, connecting France and the United States. It is fundamentally about increasing intercontinental data capacity using multi-core fiber technology.
Why it matters
Increased cable capacity reduces connectivity bottlenecks between Europe and North America to support rising data demands. This ensures more stable and faster internet access for users in these regions.
The big picture
This article provides technical engineering details and partnership information for the Petal project previously announced as a way to increase intercontinental data capacity.
The details
- Petal is built in partnership with NEC, Sumitomo Electric Industries, and Orange. - The system uses a 96 amp repeater with FIFO interfaces to amplify signals. - Capacity is 5.5x that of Marea, Meta's first transatlantic investment. - The design maintains power feeding equipment limits of 18 kV.
What's next
The cable system is expected to enter service in 2029.
