Map of submarine telecom cables

The international backbone of Internet is largely based on a network submarine fiber optic cables. There are lots of them.  TeleGeography’s free interactive Submarine Cable Map is based on Global Bandwidth research, and depicts active and planned submarine cable systems and their landing stations. Selecting a cable on the map projection provides access to the cable’s
