Submarine Cable Map
The world's undersea fiber-optic cables — the physical backbone of the internet — drawn as interactive linework with per-cable details.
About this live submarine cables map
Nearly all intercontinental internet traffic travels through submarine fiber-optic cables. This map draws the known cable routes as linework, so landing-station patterns, choke points, and transoceanic trunks are easy to inspect.
Cable routes are approximate representations published for visualization; exact cable positions are confidential for security. The catalog updates about once a day as new systems enter service.
