How many fiber optic cable lines connect globally
Fibre-optic Link Around the Globe (FLAG) is a 28,000-kilometre-long (17,398 ; 15,119 ) mostly- that connects the,,, and many places in between. By the start of 2025, the network has grown to 599 cables, spanning a staggering 1,602,092 kilometers. While these cables are heavily armored, especially in shallower coastal waters where most damage occurs, their isolation on the seabed makes them vulnerable. This page is designed to answer a simple question: what does the world internet cable map actually look like, and how do those connections work in real life? Map 1 is the modern world internet cable map (today's backbone). Show me range to terrestrial fiber nodes on the map? Is the ITU building in Geneva Switzerland within 10 km of a fibre node? Start measuring on the map to see calculations here. 1 billion in 2023, and fiber already accounts for 95% of international data traffic carried across undersea cables.
