TeleGeography’s Submarine Cable Map just lately hit a brand new milestone: depicting over 550 cable programs.
As of June 2023, that’s a whopping 485 in-service programs, with one other 70 deliberate.
The variety of cable programs we examine 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 programs in additional element.
Nonetheless, the variety of in-service programs is bigger now than in another 12 months inside the final 20 years.
What’s included on this depend?
We concentrate on publicly-known communications programs; undersea strains completely 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.
In March, I had the prospect to affix my colleague Greg Bryan on TeleGeography Explains the Web to speak via the cable-tracking course of.
You may hearken to the complete episode over right here.
What will we imply by cable programs?
The variety of cable programs we monitor is totally different from the entire point-to-point connections proven on the map.
The variety of cable programs we monitor is totally different from the entire 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 programs on our map.
The distinction between cable programs and segments is most simply demonstrated within the Atlantic. Though there are solely 12 in-service trans-Atlantic cable programs, 17 segments really cross this route.
That is made potential by programs like Vodafone’s Apollo, which just lately celebrated its twentieth birthday. Apollo connects the U.S., France, and the U.Okay. via two parallel paths—one North, the opposite South, and every with their very own pair of touchdown stations.
Interactive map followers can be accustomed to our month-to-month cable trivia. We just lately 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 appropriately guessing not two, not three, however 5!
