The Brilliant Submarine Cable Map

Source submarinecablemap.comThe Submarine Cable Map is an interactive map created by TeleGeography that illustrates the global network of undersea communication cables and their landing stations.

These submarine cables are essential for international telecommunications, transmitting data across oceans to connect different continents.

As of 2024, the map features 559 cable systems and 1,636 landing points, encompassing both operational and under-construction cables.

You can explore individual cable routes, access detailed information about each system—including ownership, capacity, and operational status—and understand the intricate web of global connectivity.

The map is regularly updated to reflect new lines, serving as a valuable tool for those interested in the infrastructure that underpins global communications.

Here are some closeups of various sections of the map:

Undersea Cables Around Europe

It’s interesting to see the density of cables in the Mediterranean as well as the cables along the coats of the UK and Norway.

Undersea Cables Around North America

The most interesting thing to me about this map is how many cables avoid Cuba between the US and South America.

Undersea Cables Around East Asia

This one is my favourite as if you look closely there are no undersea cables connecting North Korea to any other country.
