Google is building a private subsea cable that runs from Virginia to France

The first trans-Atlantic cable solely owned by a non-telecom company



What just happened? Google has announced it is constructing another private subsea cable. Set to enter service in 2020, it will cross the Atlantic Ocean from Virginia Beach in the US and stretch almost 4000 miles to the French coast.

While the Dunant cable, which is named after the founder of the Red Cross and first recipient of the Nobel Prize, Henri Dunant, will land in France, it connects Google’s North Virginia region directly to its Belgium region.


"Dunant adds network capacity across the Atlantic, supplementing one of the busiest routes on the internet, and supporting the growth of Google Cloud," wrote Google’s strategic negotiator of global infrastructure, Jayne Stowell.

Google explains that there are several options when it comes to building subsea cables: purchase capacity from an existing cable, or one being built by someone else; create a consortium of partners and build a cable together; or build one yourself.

As Google owns Dunant, which will be the first trans-Atlantic cable solely owned by a non-telecom company, it can be connected directly to the firm’s data centers and means Google doesn’t have to share bandwidth with any consortium partners. This gives it an advantage over the likes of Microsoft and Amazon, who use consortium cables to transfer data across the Atlantic.

Google hasn’t revealed the capacity of the cable, but contractor TE SubCom said it would use four fiber pairs.

Dunant, which is expected to have a lifespan of 15 to 25 years, is the fourth privately-owned Google cable. The first two run over relatively short distances, while the third, Curie, connects Los Angeles and Chile and will go into operation next year.

Nothing wrong in this. The more the cables the better I think.
