Meta plans approximately 7,000 kilometers of subsea cable between the United States and France, with Petal designed for an aggregate one petabit per second.<\/p>\n

Announced September 21 and revisited October 17, the project targets service in 2029; it is not already operating or delivering that speed to individual homes.<\/p>\n

Whose speed is one million gigabits?<\/h2>\n

One petabit equals 1,000 terabits or one million gigabits. This describes the cable system\u2019s combined design capacity, not one customer\u2019s download speed. Bits and bytes are also different units. A household plan, router or access-network bottleneck does not disappear because this cable has been announced.<\/p>\n

More pathways inside optical fiber<\/h2>\n

Meta describes two cores within a fiber as a way to increase capacity over ocean distances. Its comparison with twice today\u2019s leading transoceanic capacity is a company design claim. NEC and Sumitomo Electric participate, with Orange supporting the French landing. Partner announcements supplement primary evidence; they are not independent performance tests.<\/p>\n

A larger cable does not speed every connection<\/h2>\n

More intercontinental capacity can support rising connectivity demand. It does not guarantee shorter response times for every website or cheaper service worldwide. Independent telecom research firm TeleGeography lists Petal among Meta\u2019s solely owned cables, placing the project in the context of the company\u2019s infrastructure expansion.<\/p>\n

The next milestone is actual operation<\/h2>\n

Live Science\u2019s October 17 account was checked against the official plan, with ownership separately checked in TeleGeography\u2019s inventory. That inventory does not verify speed. These sources do not establish measured commercial performance or a final construction cost. Landing, installation, operating tests and an actual service announcement are the milestones to watch.<\/p>\n
