Final week, I joined Ciena’s Brian Lavallée and Colt’s Laurent Taieb for a dwell webinar all about submarine cable route variety and sustainability.
Individually, I coated why variety issues for submarine cables—a really well timed subject in mild of current occasions world wide.
Maybe you’ve heard concerning the a number of cable faults within the Pink 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 occurring globally, variety is significant to making sure continuity of service.
With so many a number of fault incidents occurring globally, variety is significant to making sure continuity of service.
Now, you may be questioning: how can we enhance variety?
Submarine cable variety will be seen in a number of completely different types: variety on a single route, variety of geographic route, and variety of cable touchdown stations.
Variety on a Single Route
Community operators could use completely different cables alongside the identical route. They will diversify additional with cables which have completely different homeowners.
Let’s have a look at some examples.
Variety on the Trans-Atlantic Route
There have been huge 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 centered on the New York/New Jersey space. On the European aspect, we see a heavy concentrate on the UK and northwestern France.
There are a number of exceptions, in fact, however these areas are the place cables had been usually centered earlier than 2015.

Going ahead to at present, plus the cables deliberate via 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 aspect, 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 identical development is going on.
Taking a look at pre-2017, there’s a heavy concentrate on cables going to Japan. On the U.S. aspect, issues are a bit extra various, however primarily centered 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 variety is going on on the Asian aspect.
On the North American aspect, 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 can be achieved with cables that go in several geographical instructions.
For instance, based on our knowledge, cables in India are break 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 centered on cables going east towards North America. That’s been altering during the last a number of years because it will increase variety with new cables heading north, and even a cable heading west.

Now, one key factor to remember that usually will get misplaced on this dialogue: connectivity is just not capability.
One key factor to remember that usually will get misplaced on this dialogue: connectivity is just not 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 could use cables that come into the identical common location however into completely different cable stations. They will additionally use cable stations with completely different homeowners.
A number of cables land in Jeddah, Saudi Arabia. Whereas this may increasingly appear to be a foul thought—a single level of failure—that is not the case.

There are literally a number of completely different cable stations with completely different homeowners inside Jeddah. So there actually is a variety of variety, regardless that you may even see just one common space on the map.

At TeleGeography, we at the moment are 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 knowledge set, so if you’re a Transport Networks subscriber, you’ll want to verify again usually for the most recent model.
