The Dunant submarine cable system is a 6,600km submarine cable connecting Virginia Beach in the United States to the French Atlantic coast.

The Dunant cable system is the first ever in-service undersea cable featuring a 12 fiber-pair Space Division Multiplexing (SDM) design, with a total design capacity of 25 Tbps per fiber pair, to deliver record-breaking capacity of 300 Tbps across the Atlantic.

Named in honor of Henry Dunant, a Swiss businessman, social activist, first recipient of the Nobel Peace Prize, and founder of the Red Cross, the Dunant cable system honors his memory and commitment to humanitarian ideals. 

The Dunant cable system is the second private submairne cable built by Google, following its first private and non-telecom submarine cable Curie, connecting Chile to Los Angeles.

In France, the Dunant cable lands at Orange's La Parée Préneau cable landing station in Saint-Hilaire-de-Riez. Google France has contracted with Orange to be the landing party in France. A landing party agreement governs the relationship between Google France and Orange.  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. Further, Orange receives an IRU for two fiber pairs for the entire length of the Dunant cable system. 

In the US, Google is the landing party and lands the Dunant cable at Telxius' Virginia Beach Cable Landing Station. Google maintains control of the Dunant cable system in U.S. territory and international waters.

Google selects TE SubCom to design and deploy the Dunant cable system.

The US FCC has granted cable landing license for the Dunant cable system as of March 13, 2020.
