Inside Petal: Building the World’s First Petabit-Class Transoceanic Subsea Cable

Summary

Meta announced Petal, a transoceanic subsea cable linking France and the United States over roughly 7,000 km, which it says will be the first to deliver petabit capacity at transoceanic distances.

Key facts

• Petal connects France and the United States across about 7,000 km (4,300 mi).
• Meta describes it as the first petabit-class transoceanic subsea cable.
• The cable is expected to enter service in 2029.

Why it matters

Operators and buyers of transoceanic bandwidth may eventually gain a higher-capacity route between France and the United States, though the capacity arrives only when the cable enters service in 2029.
