Submarine Cable Map, created by TeleGeography, is a visual compendium of the physical infrastructure powering the global internet. Because over 99% of all international data traffic travels through undersea fiber-optic conduits rather than satellites, this interactive map provides an invaluable perspective on global connectivity, consortium ownership, and landing stations.
Key Infrastructure Intelligence Features
- 500+ Subsea Cables Mapped: Explore trans-Atlantic, trans-Pacific, and intra-regional subsea systems connecting all inhabited continents.
- Landing Station Locator: Discover the exact coastal landing hubs where deep-sea fiber cables connect to domestic terrestrial backbones.
- Detailed Cable Profiles: Inspect cable length in kilometers, ready-for-service (RFS) dates, design capacity (Terabits/sec), and consortium owners (Google, Meta, Amazon, telcos).
- Future Build Tracking: Stay updated on upcoming high-capacity subsea routes under construction or planned for launch.
Frequently Asked Questions
Do subsea cables carry more internet traffic than satellites?
Yes. Undersea fiber cables transmit more than 99% of all transoceanic data; satellites account for less than 1% of global bandwidth.
Are the exact subsea cable paths precisely surveyed?
The map depicts generalized cable routes for security and clarity; actual surveyed bathymetric cable routes are kept proprietary to protect infrastructure.
Who owns the majority of new submarine cables?
While historic cables were built by telecom consortia, hyperscale cloud providers (Google, Meta, Microsoft, Amazon) now finance or co-own a large percentage of new routes.
