Orange announced the landing of Google’s transatlantic Dunant cable in Saint-Hilaire-de-Riez on March 13, 2020, proceeding to the first and terrestrial stage of the laying of the Dunant cable. Dunant cable system is scheduled to come into service before the end of 2020.

The Dunant cable system is the second private international submairne cable invested by Google,  spans 6,600km connecting Virginia Beach in the United States to Saint-Hilaire-de-Riez in the French Atlantic coast.

As the “Landing Party” and owner of the French part of the Dunant cable, Orange has completely refurbished the historic La Parée Préneau cable landing station in Saint-Hilaire-de-Riez, which was no longer in use, to house the terminal equipment for the Dunant cable system. This area is a strategic location, close to the main connectivity hubs on this side of the Atlantic. From the La Parée Préneau cable landing station, Orange is deploying terrestrial optical fibres in France between Saint-Hilaire-de-Riez and Paris to route its traffic on the Dunant cable system to the capital's major Data Centres and will also provide service to the rest of Europe and major international Data Centres.

Orange entered a landing party agreement with Google France. Google France conveys to Orange ownership of the portion of the Dunant cable system that extends 12 nautical miles from the shores of France. Orange grants Google France an IRU for the same portion of the Dunant cable system. On the other hand, Orange receives an IRU for two fiber pairs during the entire lifetime of the Dunant cable system, with a capacity of up to 30Tbps each, enough to transfer a 1GB video in 30 microseconds. Orange will thus be able to meet the massive growth in demand for data and content exchanged between Europe and the United States for several years to come.

Dunant is the first submarine cable to connect the United States to France in more than 15 years and is designed to combine the most advanced technologies featuring High Fiber Count (HFC) of 12 fiber pairs and Space Division Multiplexing (SDM), to deliver record-breaking capacity of at least 250Tbps across the Atlantic.
