Meta Announces Project Waterworth: Building the World’s Longest Subsea Cable
Meta has unveiled its ambitious plan, Project Waterworth, to construct the world’s longest subsea cable system. This groundbreaking project will span over 50,000 kilometers, surpassing the Earth’s circumference and connecting five continents.
The primary objective of Project Waterworth is to provide industry-leading connectivity to key regions such as the U.S., India, Brazil, and South Africa. Meta believes that this initiative will foster greater economic cooperation, promote digital inclusion, and create opportunities for technological advancement in these areas.
According to Meta, Project Waterworth represents a multi-billion-dollar, multi-year investment aimed at enhancing the scale and reliability of the global digital infrastructure. The project will establish three new oceanic corridors that will facilitate high-speed connectivity necessary for driving AI innovation worldwide.
One of the key highlights of Project Waterworth is the construction of the longest 24 fiber pair cable system in the world. Meta plans to deploy cutting-edge routing techniques to maximize the efficiency of the cable, even in deep waters reaching depths of up to 7,000 meters. Additionally, enhanced burial techniques will be utilized in high-risk fault areas near the coast to mitigate potential damage from ship anchors and other hazards.
Meta’s CEO emphasized the critical role of capacity, resilience, and global reach in supporting the evolving landscape of AI and emerging technologies. Project Waterworth aims to democratize access to these innovations, ensuring that individuals worldwide can benefit from the transformative power of AI regardless of their geographical location.
As Meta embarks on this monumental endeavor, the company remains committed to advancing global connectivity and fostering technological progress on a truly global scale. Project Waterworth is poised to redefine the digital landscape, setting new benchmarks for subsea cable projects and laying the foundation for a more connected and technologically empowered future.
