Bell Labs can send 10 gigabit per second over existing copper wires up to 30 meters so it solves the fiber-to-residence problem. Fiber can go past houses and then the copper can take the signals into the house. Alcatel-Lucent’s Bell Labs can now run 1-to-10 gigabit per second broadband signals from the curb to the residence using the existing copper telephone lines already there.
It is called XG Fast
10 gigabits per second can go 30 meters
1 gigabit per second symmetrical can go 70 meters.
XG.fast as an extension of G.fast. G.fast is the successor to VDSL2 — the technology that is used by most FTTC (fiber-to-the-cabinet) installations around the world. Paired with FTTC, VDSL2 offers speeds of up to 150Mbps, G.fast is up to around 1.25Gbps — and XG.fast is from 2Gbps all the way up to 10Gbps.
Don’t expect a 10Gbps/10,000Mbps connection any time soon, however. Further advances to FTTC and VDSL2, and then G.fast — which is in the process of being ratified by the ITU — are the next steps that will be rolled out by ISPs over the next few years. G.fast and its promise of 1Gbps will require running fiber a bit closer to the home — probably FTTdp (distribution point; either under the sidewalk, or up a pole) — and will thus cost a significant amount of capital expenditure. XG.fast will almost certainly require FTTB (fiber to the basement), though FTTdp may be possible in some situations.
