Goggle's New TransAtlantic SOL Cable: The March South
Google's SOL cable is the first Trans-Atlantic network to connect Florida to Europe with a landing at the Telxius Santander CLS on the Northern Spanish coast. The other cable, Nuvem, announced some time ago, will link the Myrtle Beach, South Carolina CLS owned and operated by DC BLOX to a landing near Lisbon. Details are sparse regarding SOL, but it will probably be similar in performance and design to the 16 fibre pair Nuvem cable that clocks 384 Tbps. The Florida landing is in the Palm Coast area between Jacksonville and Orlando. An interesting feature is that both cables do island hopping. Both cables land in Bermuda and Azores (where a US Air Force base is located). Island hopping serves three goals. The first is power to offset voltage drop. Intermediate power feeding en route improves throughput. The more often a cable can feed, the higher the bandwidth. The other factor is optical amplifier noise. Amplification introduces noise which accumulates from amplifier to amplifier. ...
