Meta announces Petal transatlantic cable delivering 1 petabit per second
↗
Meta announced Petal, a new subsea cable linking France and the United States that will deliver 1 petabit per second of bandwidth.
The cable will increase transatlantic capacity, supporting Meta's growing data demands and offering redundancy for European connectivity. Its deployment will require upgrades to landing stations and may affect network planning for other operators. The project highlights Meta's investment in infrastructure to meet future traffic growth.

Petal will deliver 1 petabit per second across the Atlantic.
The cable uses 48 fiber pairs and a two-core fiber design.
Installation is scheduled for 2029 with partners NEC and Sumitomo Electric.
THE READ
What the cluster adds up to.
Meta's Petal cable will provide 1 petabit per second of capacity between France and the United States, doubling the bandwidth of its previous Anjana cable system.
The project requires Meta to partner with NEC and Sumitomo Electric for manufacturing and installation, and to coordinate with Orange for the French landing point.
Petal's two-core fiber design introduces technical challenges such as crosstalk and attenuation, which Meta plans to mitigate through ultra-pure silica and careful refractive index control.
The cable's deployment will increase demand for repeaters and may require upgrades to existing landing station equipment to handle the higher capacity and signal processing needs.
By creating a dedicated high-capacity route, Petal aims to improve resilience for Meta's services and support future growth in transatlantic data traffic, potentially influencing broader subsea cable planning in the industry.
