Submarine cable investment has accelerated as hyperscale cloud providers join traditional telecom carriers as cable system investors and consortium members, driving new capacity across transatlantic, transpacific, and intra-Asia routes alongside emerging cable systems linking Africa and the Middle East into the global network.
The database tracks system-level detail including cable route, landing stations, consortium members, and design capacity, alongside planned new systems intended to relieve capacity constraints on aging cable infrastructure and to diversify routing away from congested chokepoints.
Active/Planned Cable Systems, Growth (approx.)
Looking ahead, Untapped Markets expects submarine cable investment to remain robust, as hyperscale cloud providers, AI-driven data demand, and route diversification continue to expand the global subsea network.
The Global Submarine Cable Infrastructure Database is developed using a structured, multi-source research process designed to ensure accuracy and consistency across every tracked record.
The research team defines the full universe of submarine cable systems to be tracked within scope, drawing on regulatory filings, industry association membership lists, company disclosures, and prior desk research to establish an initial master list.
Each record is populated using primary sources including company announcements, regulatory and permitting filings, government databases, and, where available, direct outreach to operators and developers, cross-checked against secondary sources such as industry reports and trade press coverage.
Records are standardized into a consistent schema covering location, capacity or scale, ownership, operational status, and timeline detail, allowing like-for-like comparison across all covered countries and regions.
The database is reviewed on a periodic basis to reflect newly announced projects, status changes, and ownership updates, with the 2026 reference year reflecting the most recent verified data snapshot at time of publication.
More than 600 submarine telecommunications cable systems connect continents and carry over 95% of global international internet traffic. The Global Submarine Cable Infrastructure Database tracks active, under-construction, and planned submarine cable systems, providing detailed intelligence on routes, landing stations, ownership, design capacity, and operational status worldwide.
Countries including the United States, United Kingdom, France, Japan, Singapore, Australia, India, and Brazil serve as major global connectivity hubs with extensive submarine cable landing infrastructure. The database enables country-level benchmarking of global digital connectivity networks.
The database covers cable systems owned or supported by leading organizations including Google, Meta, Microsoft, Amazon, Orange, Vodafone, Tata Communications, China Mobile, Telstra, and other global telecom operators and consortiums. Ownership structures and consortium participation are tracked for each system.
The database includes cable system name, route, landing stations, countries served, cable length, owners, consortium members, design capacity, operational status, and planned expansion projects, providing comprehensive intelligence on global submarine telecommunications infrastructure.
Growth is driven by cloud computing, artificial intelligence (AI), international data traffic, hyperscale data centers, digital transformation, content delivery networks, and increasing demand for high-capacity global internet connectivity. Technology companies and telecom operators continue investing heavily in new subsea cable systems.
The database is designed for telecommunications companies, cloud providers, hyperscale operators, investors, governments, consultants, network infrastructure providers, research organizations, and market analysts seeking detailed submarine cable intelligence.
