TeleGeography’s Submarine Cable Map just lately hit a brand new milestone: depicting over 650 cable techniques.
As of February 2025, that’s a whopping 570 in-service techniques, with one other 81 deliberate.
The variety of cable techniques we research is continually growing. This is because of huge funding on this infrastructure—each alongside main routes and to small islands—in addition to our ongoing efforts to trace international techniques in additional element.
The variety of in-service techniques is bigger now than in some other yr inside the final 20 years.
What’s included on this rely?
We deal with publicly-known communications techniques; undersea traces solely devoted to energy transmission, analysis networks, and personal authorities use are excluded. As soon as cables are retired, we take away them from our on-line map.
A number of seasons in the past, I joined my colleague Greg Bryan on TeleGeography Explains the Web to speak by way of the cable-tracking course of.
You possibly can take heed to the total episode over right here.
What can we imply by cable techniques?
The variety of cable techniques we monitor is totally different from the whole point-to-point connections proven on the map.
The variety of cable techniques we monitor is totally different from the whole point-to-point connections proven on the map.
Every cable system is uniquely designed to suit its capability necessities and native geography. As such, it could comprise a number of segments or branches, as do over half of the techniques on our map.
The distinction between cable techniques and segments is most simply demonstrated within the Atlantic. Though there are solely 13 in-service trans-Atlantic cable techniques, 17 segments truly cross this route.
That is made potential by techniques like Vodafone’s Apollo, which celebrates its twenty second birthday this month. Apollo connects the U.S., France, and the U.Ok. by way of two parallel paths—one North, the opposite South, and every with their very own pair of touchdown stations.
Interactive map followers shall be acquainted with our cable trivia. One month, we requested map viewers to ponder the typical variety of landings per system on the map. Our winner acknowledged the complexity of subsea system design by accurately guessing not two, not three, however 5!
Together with trivia questions, our staff continuously rolls out new map options. Because of a current replace, customers can now:
- Search by area and route. Navigate to the brand new Area and Route pages by typing Related to [region name] or Related to [route name] within the search subject.
- Filter choices by a variety of RFS years. A Filter button is on the market within the sidebar on Area, Nation, Touchdown Level, Route, and Provider pages that return an inventory of three or extra cables.
