EUNetwork's New Paris/Milano Route

Image
The well respected wide area network carrier has lit a new, shorter path connecting Milano and Paris data centers. While I believe you should never limit yourself to one vendor, EUNetworks is a very safe choice because it does the fundamentals well and is commercially flexible. The new route spans 1057 kilometers. EU did not provide a latency estimate, but it takes roughly 5.1 microseconds to traverse a kilometer. So multiply by 1057*2 and the RTD is approximately 10 ms. One diversity edge is that the route avoids Lyon. I recommend network planners consider to further diversity their network portfolio and reduce risk as a financail analysts might say. 

The Best Subsea Trans-Atlantic Cable For General Bandwidth: Google's Dunant

Image
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 t...
