Vision Behind Meta’s Project Waterworth
The ambitious plan for building the world’s longest undersea internet cable is a part of Meta’s latest project, Waterworth. This undersea cable, spanning over 50,000 kilometers, will connect multiple continents, particularly regions, including India, the US, South Africa, Brazil, and others. The primary vision for developing this project is to support the growth of AI technologies by providing high-speed and reliable internet connections.
Through reliable connectivity, this plan will enable greater digital expansion across the regions under this project’s geographical coverage. Apart from developing a strong and supportive infrastructure for AI development, Project Waterworth will cover the digital gap in key regions by enhancing internet access and connectivity. This project is seen as a crucial investment for supporting Meta’s advancements in AI and reinforcing its industrial position.

Meta’s Project Waterworth Utilizes High-Capacity Fiber Tech
The submarine cable initiative by Meta under its Waterworth project is aimed to build the world’s longest undersea internet cable. This initiative will feature high-capacity fiber optic technology by utilizing 24 fiber pairs, which has the highest capacity available for data transmission currently. To avoid disturbances from sea traffic, these cables will be deployed at a deep depth of up to 7,000 meters. Additionally, in areas with high risks like coastlines, special burial methods will be used to protect the cable from damage caused by ship anchors and other damages.
The resilient design for Meta’s latest submarine cable project is developed to ensure durability, rapid deployment, and reliable connectivity, as this high-capacity optic fiber cable technology can withstand harsh underwater conditions. Additionally, advanced AI technology will be used to regularly monitor the cable’s health for preventive maintenance and to avoid disruptions.
Major Tech Firms Invested in Meta’s Project Waterworth
To support expanding bandwidth demands for video streaming, cloud computing, and AI applications, Meta has developed the plan for the world’s longest undersea internet cable. However, this multinational tech company is not the sole investor in this ambitious project. Waterworth, which aims to build the world’s longest and high-capacity submarine cable, welcomes investment by major global tech firms, including Instagram, WhatsApp, Microsoft, BSNL, Telstra, Ericsson, BT, and others.
World’s Longest Undersea Internet Cable: Geographical Coverage
Spanning over a geographical coverage of 50,000 kilometers, the world’s largest and highest-capacity internet cable will cover a longer area than Earth’s circumference. This multibillion-dollar investment will take multiple years to complete and will cover key routes, including India, South Africa, the US, and other regions in the world’s five major continents. The largest market for Meta among these regions is India, and the world’s longest undersea internet cable project will greatly assist in accelerating the nation’s digital economy.
Meta’s Project Waterworth: Potential Impacts
In addition to providing high-speed and reliable internet connectivity, Meta’s Project Waterworth will significantly impact the regions under its geographical coverage. The possible key impacts of this innovative and ambitious project are:
1. Improved Digital Infrastructure: A major support to reliable internet connectivity, especially in regions with limited internet access, will be provided by this project, which will build the world’s longest submarine cable.
2. Employment Opportunities: From the construction of this high-capacity optic fiber cable project to maintenance post-construction, this project will significantly create job opportunities in the fields of engineering, technology, etc.
3. Economic Growth: With advancements in digital infrastructure, businesses operating in the key regions under this project’s geographical coverage can easily access new markets and facilitate e-commerce, leading to strong economic growth.
Conclusion
Meta’s plan for the world’s longest undersea internet cable is indeed a significant announcement, as it will greatly influence the future of digital transformation worldwide. Its high bandwidth capacity will support faster AI deployment, provide more encouragement to entrepreneurship, and improve access to online learning opportunities, remote consultations with healthcare professionals, etc.
This cable will be deployed at a deep depth; however, it will still be vulnerable to natural disasters that can cause major disruption. This major challenge highlights the importance of top-tier infrastructure maintenance and security measures. Over 99% of international data travels through submarine cables, and that’s the primary reason that Meta has opted for undersea internet cables to strengthen internet connectivity worldwide with its Waterworth project, an ambitious project that will influence the digital lives of millions of users.
