Alcatel-Lucent's XG-FAST Pushes 10,000Mbps Over Copper Phone Lines
Mark.JUK (1222360) writes The Bell Labs R&D division of telecoms giant Alcatel-Lucent has today claimed to set a new world record after they successfully pushed "ultra-broadband" speeds of 10,000 Megabits per second (Mbps) down a traditional copper telephone line using XG-FAST technology, which is an extension of G.fast (ITU G.9700).
G.fast is a hybrid-fiber technology, which is designed to deliver Internet speeds of up to 1000Mbps over runs of copper cable (up to around 250 meters via 106MHz+ radio spectrum). The idea is that a fiber optic cable is taken closer to homes and then G.fast works to deliver the last few meters of service, which saves money because the operator doesn't have to dig up your garden to lay new cables. XG-FAST works in a similar way but via an even shorter run of copper and using frequencies of up to 500MHz. For example, XG-FAST delivered its top speed of 10,000Mbps by bonding two copper lines together over just 30 meters of cable.

So in real life, around 20m, give or take 12m.

The rest of us still do local caching proxies and QoS hackery to make the most of our 2-3 Mbps.
I want to delete my account but Slashdot doesn't allow it.
To what, the DSLAM? A few microseconds. To the IP drain? The same as before. Also, this does not beg the question.

Big ups to my garden, big ups to my hoe.
What the dill w/ my weeds and my dill-yo?
Gotta keep the green flowing round my grill-yo.
My lyrics is tight.
My rhymes on target.
I drop fatter beets
Than a farmer's market.
This is a good way to get high speeds into multi-tenant buildings. You bring fiber into the wire closet and then run this over the existing copper to the offices, apartments, suites throughout the building.

30m is pretty short run, 10ge will do 100m over 6a or 7. For office buildings it's normally pretty easy to get new cable in place not so much with apartment complexes.
No sir I dont like it.
Verizon does exactly that with FiOS in some MDU installs. They run fiber to the wire closet, and the runs to the units are VDSL2.
Other than just wanting to sound super awesome is there any reason why they aren't using Gbps instead of Mbps? It's sort of like saying a new car has a top speed of a bazillion picometers per second.
as soon as you get out of the shade of the equipment cabinet, it's dead, Jim. yeah, that'll work. dig up the shrubs to put a 2 cubic meter cabinet and power stand next to the house. oh, yeah, I'm going to pester the phone company for this now.
plus 106+ MHz impacts aviation radio with interference. if the cabinet blocking your dryer vent doesn't get you, the 737 in your living room will.
if this is supposed to be a new economy, how come they still want my old fashioned money?
