Bell Labs achieved 1Gbps symmetrical over just 70 meters on a single copper pair and 10Gbps was achieved over a distance of 30 meters by using two pairs of lines bonding. Both tests used standard copper cable provided by a European operator. The speeds are impressive but the distance is clearly more problematic, which might mean more of a choir for operators as they’d need to bring the accompanying fibre optic cable even closer to your doorstep at this range you could almost call it FTTB.

The question for some operators will be whether or not it’s even worth following the G.fast to XG-FAST path, as opposed to simply putting fibre optic cable in the ground and having less to worry about in the future.
