Feb 13, 2025 | Posted by Abdul-Rahman Oladimeji

Meta plans to deploy a multi-billion dollar cable that will span the globe, a 50,000km (31,070 mi) Project called Waterworth. This project is expected to be the world's longest 24 fiber pair submarine cable, connecting the US, India, Brazil, South Africa, and other regions.

The company said that it would deploy 'first-of-its-kind routing,' allowing it to be laid at depths up to 7,000 meters (23,000 ft), and use enhanced burial techniques in high-risk fault areas, such as shallow waters near the coast.

"Project Waterworth will be a multi-billion dollar, multi-year investment to strengthen the scale and reliability of the world’s digital highways by opening three new oceanic corridors with the abundant, high speed connectivity needed to drive AI innovation around the world," said Meta network engineers Gaya Nagarajan and Alex-Handrah Aimé.
