The Best Subsea Trans-Atlantic Cable For General Bandwidth: Google's Dunant
Technology: Spatial division multiplexing. Fibre Pairs: 12. Founding Father: Google Consortium Members: Google & Orange. The French PTT is best described as a junior partner. RFS: January, 2021. Route: Direct Ashburn Equinix to Paris. Landings: Virginia Beach, VA. Saint-Hillaire-de-Riez. Notable Features: Second cable after Marea to directly link Ashburn Equinix to Europe. Dunant was first subsea network in the world to deploy spatial division multiplexing and and achieve a two digit fibre pair count. Dunant was the beginning of the spatial division multiplexing revolution. It was the first cable to leapfrog from the standard 4 to 8 fibre pair coherent optics paradigm for the Atlantic to the 12 to 32 pair spatial division multiplexing model that dominates today. Dunant went live January 19, 2021 with 12 fibre pairs and lit capacity of 250 terabits per second. However, the design capacity was even higher, 300 Tbps. The cable is named after the Swiss businessman Henri Dunant
