Meta announced Petal, a subsea cable system expected to enter service in 2029 that will deliver 1 petabit per second (Pbps) of capacity between France and the United States over approximately 7,000 km. Petal will be the first transoceanic subsea cable to deploy multi-core fiber technology at scale, doubling capacity per fiber without proportional increases in power or physical infrastructure. The cable is being built in partnership with NEC and Sumitomo Electric Industries, with support from Orange on the French landing.
