Meta’s Petal cable targets petabit capacity across the Atlantic
Petal is planned as a roughly 7,000-kilometer cable connecting France and the United States, using multi-core fiber at scale and targeting service in 2029. Its capacity and fiber choices matter to engineers building global infrastructure.
- What
- Petal is a planned 7,000-km subsea cable linking France and the United States, designed for 1 Pbps capacity.
- How
- It uses 2-core fiber technology at scale in a 24-fiber-pair system, equivalent to 48 conventional fiber pairs.
- Why it matters
- The design doubles Anjana’s capacity without a proportional increase in power or physical infrastructure.
