A short range, high speed technology standard for broadband over copper phone lines has been approved by the International Telecommunications Union. The G.fast standard is intended to make fiber-class speeds possible over legacy lines, with a maximum distance of 400 meters between the customer and the nearest fiber node.
Practical distances, though, are much shorter. “Service rate performance targets” – total bandwidth which can be split between up and down loads – are…
