Google’s Dunant subsea cable connecting the US to the French Atlantic coast is now officially ready for service (RFS).

Named after Henry Dunant, the founder of the Red Cross and first person to win a Nobel Peace Prize, the 6,400km system is the first to deliver a 12-fibre pair space-division multiplexing (SDM) designed cable. As such, Dunant will deliver a 250Tbps across the Atlantic, amounting to enough to transmit the entire digital Library of Congress three times every second. 

Dunant was built in partnership with SubCom, which to engineered, manufactured and installed the Dunant system on time despite the ongoing global pandemic.

The cable has also been designed to be as cost effective as possible with additional fibre pairs and power-optimised repeater designs. Leveraging SDM technology, allows pump lasers and associated optical components to be shared among multiple fibre pairs rather than dedicated pump lasers per fibre.

This new piece of infrastructure will be used to support Google’s global cloud network which enables its customers the ability to run their apps with open, hybrid, and multi-cloud solutions, use advanced security tools and transform how their employees connect and collaborate, to name a few.

“…while we haven’t hastened the speed of light, we’re still very much hard at work at bringing you a better and faster cloud,” said Chris Ciauri (pictured), president, of Google Cloud EMEA, in a blog post.

Earlier this month, Telxius confirmed the availability of  its capacity on the Dunant cable pairing it with existing MAREA cable across the Atlantic to create a loop-based system that interconnect at each landing point. 

While back in January, Orange also announced that its capacity on Dunant cable was RFS. The cable has 12 fibre pairs with over 30Tbps of capacity. As the French landing provider. Orange is responsible for the operation and maintenance of the French landing station and will also supply land connectivity for the cable.
