Final week, I joined Ciena’s Brian Lavallée and Colt’s Laurent Taieb for a dwell webinar all about submarine cable route range and sustainability.
Individually, I coated why range issues for submarine cables—a really well timed matter in mild of latest occasions around the globe.
Maybe you’ve heard concerning the a number of cable faults within the Purple Sea in February or off of West Africa in March? There have been additionally faults off of East Africa earlier this month.
With so many a number of fault incidents taking place globally, range is significant to making sure continuity of service.
With so many a number of fault incidents taking place globally, range is significant to making sure continuity of service.
Now, you could be questioning: how will we enhance range?
Submarine cable range may be seen in a number of totally different kinds: range on a single route, range of geographic route, and variety of cable touchdown stations.
Variety on a Single Route
Community operators might use totally different cables alongside the identical route. They will diversify additional with cables which have totally different house owners.
Let’s have a look at some examples.
Variety on the Trans-Atlantic Route
There have been massive modifications on the trans-Atlantic route throughout the final 10 years or so.
The highest map within the determine under, pre-2015, reveals a heavy focus of cables targeted on the New York/New Jersey space. On the European facet, we see a heavy give attention to the UK and northwestern France.
There are just a few exceptions, in fact, however these areas are the place cables had been usually targeted earlier than 2015.

Going ahead to right now, plus the cables deliberate by means of 2026, we see a broad distribution of cables from Canada to the southeastern United States. There are a number of new touchdown websites in Virginia Seashore and Myrtle Seashore.
Equally, on the European facet, we see a broad distribution from Scandinavia to the Iberian Peninsula, with a number of new landings in southwestern France, northern Spain, western Eire, Portugal, and Norway.
Variety on the Trans-Pacific Route
Within the different main ocean, the Pacific, an analogous development is occurring.
Taking a look at pre-2017, there’s a heavy give attention to cables going to Japan. On the U.S. facet, issues are a bit extra various, however primarily targeted on Oregon and southern California.

The underside map, 2017–2026, reveals that a number of cables are nonetheless going to Japan, but additionally to Singapore, the Philippines, Taiwan, and Indonesia. Way more range is occurring on the Asian facet.
On the North American facet, together with a brand new cable touchdown in northern California (Eureka), we now see cables going to Canada and Mexico.
Variety of Geographic Route
Variety may also be achieved with cables that go in numerous geographical instructions.
For instance, in keeping with our information, cables in India are cut up roughly 50/50 between heading west towards Europe and east towards Singapore and the remainder of Asia.

Australia is an fascinating case.
For years, it was closely targeted on cables going east towards North America. That’s been altering during the last a number of years because it will increase range with new cables heading north, and even a cable heading west.

Now, one key factor to keep in mind that always will get misplaced on this dialogue: connectivity will not be capability.
One key factor to keep in mind that always will get misplaced on this dialogue: connectivity will not be capability.
Don’t be fooled; cable maps present connectivity, not how capability is deployed.
The Center East has substantial cable connectivity in all instructions, however 84% of the area’s used worldwide capability is linked to Europe.

Variety of Cable Touchdown Stations
Lastly, community operators might use cables that come into the identical normal location however into totally different cable stations. They will additionally use cable stations with totally different house owners.
Numerous cables land in Jeddah, Saudi Arabia. Whereas this will likely seem to be a foul concept—a single level of failure—that is not the case.

There are literally a number of totally different cable stations with totally different house owners inside Jeddah. So there actually is numerous range, regardless that you may even see just one normal space on the map.

At TeleGeography, we are actually including cable touchdown station data to our Transport Networks Analysis Service submarine cable profiles.
The place obtainable, this consists of:
- Station title
- Station proprietor
- Different cables in the identical station
We’re steadily updating and increasing this information set, so in case you are a Transport Networks subscriber, you should definitely verify again usually for the most recent model.
