Submarine Cable Map

Caitlin Dempsey


TeleGeography, a telecom data company, has released the 2014 version of its Submarine Cable Map.  

The map shows 285 cable systems current in existence or due online by 2015 around the world.  Fiber optic cable crosses the world’s ocean floors, serving as the backbone of the Internet.  

This network of criss-crossed cabling enables the world to stay connected.

The world map shows 263 in-service and 22 planned undersea cables.  The countries are color-coded to show how many international cable systems are connected to that destination.  

The main map also highlights details about key cable landing stations in Hawaii, Southern Florida, New York, New Jersey, Cornwall, Singapore, Hong Kong, Tokyo, and Sydney.

An inset topography map shows geographically accurate submarine cable paths and the locations of seven cable maintenance agreement zones.

The global cable map also includes several infographics including: causes of cable faults, 2008-2011, number of cable breaks by country, 2008-2012, and mean time to commence repair by country, 2008-2012.

For a more interactive version, TeleGeography also has an interactive Submarine Cable Map.  This online map is updated regularly and pulls data from the company’s Global Bandwidth Research Service.

 Users can click on individual cable links to see the submarine cable name, owners, and landing points. Users can also return a filtered list of cable lines by year by typing in “ready for service” and selecting the year of interest.
