Project Waterworth: Meta’s 50,000km Cable to Redefine Global Connectivity

A groundbreaking subsea cable initiative, Project Waterworth, has been announced by Meta is set to become the longest subsea cable system in the world. Spanning over 50,000 km—longer than Earth’s circumference—the project will connect five continents, including the U.S., India, Brazil, and South Africa, using the highest-capacity technology available.

The multi-billion-dollar investment aims to enhance global connectivity, boost economic cooperation, and support digital inclusion. In India, it is expected to accelerate digital infrastructure growth and strengthen the country’s digital economy.

We’ve driven infrastructure innovation with various partners over the past decade, developing more than 20 subsea cables. This includes multiple deployments of industry-leading subsea cables of 24 fiber pairs – compared to the typical 8 to 16 fiber pairs of other new systems. These investments enable unmatched connectivity for our world’s increasing digital needs.

With Project Waterworth, we continue to advance engineering design to maintain cable resilience, enabling us to build the longest 24 fiber pair cable project in the world and enhance overall speed of deployment. We are also deploying first-of-its-kind routing, maximizing the cable laid in deep water — at depths up to 7,000 meters — and using enhanced burial techniques in high-risk fault areas, such as shallow waters near the coast, to avoid damage from ship anchors and other hazards.
