Meta has announced the deployment of the Petal subsea cable, marking a significant advancement in global telecommunications. Spanning approximately 7,000 kilometers between the United States and France, Petal is the first petabit-class transoceanic cable, doubling the capacity of existing systems. This project is a collaboration with NEC Corporation and Sumitomo Electric Industries, utilizing specialized 2-core fiber technology to enhance data transmission reliability. The cable is crucial for supporting Meta's artificial intelligence expansion, as undersea cables are responsible for over 99% of international data exchanges. Additionally, Meta's Project Waterworth aims to establish a 50,000-kilometer global subsea cable network connecting five continents. This multi-billion-dollar investment is expected to significantly improve high-speed connectivity across strategic regions. The Petal cable's deployment represents a major technological milestone in the telecommunications sector.
