Inside Petal: Building the World’s First Petabit-Class Transoceanic Subsea Cable
Meta is building Petal, the first transoceanic subsea cable with petabit capacity connecting France and the United States. It fundamentally focuses on deploying multi-core fiber technology at scale to double current data capacity.
Why it matters
This infrastructure addresses increasing demand for reliable intercontinental connectivity, affecting how data traffic like video calls and streaming moves between Europe and North America.
The big picture
This article provides technical engineering details for the Petal project previously mentioned in reports about Meta's deployment of a petabit-capacity cable.
The details
- The cable uses 2-core fiber in a 24 fiber-pair system. - It utilizes a single-body 96 amp repeater with FIFO interfaces. - The project uses "2C Z-PLUS ULL Fiber" from Sumitomo Electric Industries. - Capacity is 5.5x that of Meta's first transatlantic investment, Marea.
What's next
The cable system is expected to enter service in 2029.
