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.

Down your cables goes the frosty piss!
I usually big up my barden to pant the roses.
What is the latency?
All my telco worker friends grumble about being forced to praise their customers' horticultural skills on their site visits.
Buy the book BANNED by Costco!
Buy the book that Google can't seem to find in their search engine!
America!

"Dinesh D’Souza, in response to the news of Costco removing his latest book, America: Imagine A World Without Her, from its shelves, made the following statement on July 8.
Today, I was stunned to learn that Costco had pulled my latest book, America: Imagine A World Without Her, from all of its stores. This was despite the fact that the book had sold very well at the chain and that my movie of the same name was releasing on over 1,000 screens the very next day. Today, I am disappointed to learn that this news has been confirmed by Costco. This action confirms the suspicions of all freedom-loving Americans and is a direct attack on my livelihood which I take very seriously.
In a free society, Costco is free to ban my book, but their customers are also free to shop at other stores which don’t censor books. In the book and the movie, I talk about the shaming of Americans and a culture of intimidation and censorship that has been spearheaded by the President himself. It’s one thing for Costco executives to pal around with President Obama and donate almost exclusively to Democrats. But to turn their company into a tool for suppressing dissent against the government is another matter.
I urge all Americans to watch our film in their nearest theater and buy the book from an establishment that honors freedom of speech. Once they do that, they will understand why the President and his allies are so afraid of this message and determined to keep it from reaching the American people."
Or is it actually true that you people are too lazy to read anything that is longer than a blog post?
So in real life, around 20m, give or take 12m.
He tried to kill me with a forklift!
That is going to barely make it from the pole to the house. Tack on how much the gear will cost and this is cheaper than pulling fiber? Pull the fiber and be done with it 2 strands of single mode from the 70's would still get me any speed available today, sure it might need C/DWDM to do it but it's doable with standard gear.
No sir I dont like it.
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.
Glad I don't have to "big up" my garden.
You'ze can like call me Ali-G. Boo-yah-kah-sha!
Big up you'selves.
Because you know they upgrade their networks right away
Most people's homes have phone wiring from the 80s -- too slow to handle modern DSL anyway.
It's entirely useless.
Even in areas where all the cabling is buried(which definitely isn't all of them) how much do you save by putting some fancy and expensive widget within a couple hundred meters of every customer's location? Aside from the joys of managing a zillion touchy network devices out on the poles in all winds and weathers, you'd better hope that there's no secondary market for such gear or people will be harvesting them faster than you can install them...
Or are we going to have to put up with an idiotically asynchronous connection like we already do with DSL (768K) now?

THANK GOD!!!
Why I vote Democrat
I vote Democrat because I believe it’s okay if our federal government borrows $85 Billion every single month.
I vote Democrat because I care about the children but saddling them with trillions of dollars of debt to pay for my bloated leftist government is okay.
I vote Democrat because I believe it’s better to pay billions of dollars to people who hate us rather than drill for our own oil, because it might upset some endangered beetle or gopher.
I vote Democrat because I believe it is okay if liberal activist judges rewrite the Constitution to suit some fringe kooks, who would otherwise never get their agenda past the voters.
I vote Democrat because I believe that corporate America should not be allowed to make profits for themselves or their shareholders. They need to break even and give the rest to the federal government for redistribution.
I vote Democrat because I’m not concerned about millions of babies being aborted, so long as we keep all of the murderers on death row alive.
I vote Democrat because I believe it’s okay if my Nobel Peace Prize winning President uses drones to assassinate people, as long as we don’t use torture.
I vote Democrat because I believe people, who can’t accurately tell us if it will rain on Friday, can predict the polar ice caps will melt away in ten years if I don’t start driving a Chevy Volt.
I vote Democrat because Freedom of Speech is not as important as preventing people from being offended.
I vote Democrat because I believe the oil companies’ profit of 3% on a gallon of gas is obscene, but the federal government taxing that same gallon of gas at 15% isn’t obscene.
I vote Democrat because I believe a moment of silent prayer at the beginning of the school day constitutes government indoctrination and an intrusion on parental authority .. but sex education, condom distribution and multiculturalism are all values-neutral.
I vote Democrat because I agonize over threats to the natural environment from CO2, acid rain and toxic waste .. but I am totally oblivious of the threats to our social environment from pornography, promiscuity and family dissolution.
I vote Democrat because I believe lazy, uneducated stoners should have just as big a say in running our country as entrepreneurs who risk everything and work 70 hours per week.
I vote Democrat because I don’t like guns .. so no one else should be allowed to own one.
I vote Democrat because I see absolutely no correlation between welfare and the rise of illegitimacy.
I vote Democrat because I see absolutely no correlation between judicial leniency and surging crime rates.
I vote Democrat because I believe you don’t need an ID to vote but you do to buy beer.
I vote Democrat because I believe marriage is obsolete, except for homosexuals.
I vote Democrat because I think AIDS is spread by insufficient funding.
I vote Democrat because I think “fairness” is far more important than freedom.
I vote Democrat because I think an “equal outcome” is far more important than equal opportunity.
I vote democrat because I would rather hide in a class room while others fight for my freedom.
I vote democrat because I’m not smart enough to own a gun and I need someone else to protect me.
I vote democrat because I would rather have free stuff than freedom.
And lastly, I vote Democrat because I’m convinced that government programs are the solution to the human condition, NOT freedom.
... to move it away from my pole to the garden.
It little behooves the best of us to comment on the rest of us.
Yupper, that's /. Also, just 1st and last sentence is all we care 'bout.
CAP = 'nipple' - I can't make things like this up :)!
This is just a maintenance nightmare! The short RF stub of copper will be deadly trap for privacy, and unreliability.
which didn't need much help anyway.
If you are not living on top of the next guy, you are still SOL.
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.
Or are we going to have to put up with an idiotically asynchronous connection like we already do with DSL (768K) now?
You probably mean Asymmetric.
I would think consumer and small business Internet access will keep on being asymmetric for the most part, whatever the technology.
Most users on those markets are consumers and not producers of data, which means more downloads than uploads.
Combine that with bandwidth being ALWAY scarce, you will have Engineers , network architects, product managers
and management designing their products taking that into account.
The market need for a symmetrical or a reverse ratio of uploads to downloads on the consumer segment is minuscule.
And how many well-thrown baseballs is that exactly?
At this point, I can't even use the speeds that the ISP claims to provide because all of the content sources that I attempt to use can't seem to saturate my existing bandwidth. This is especially noticeable with video streaming services which seem to be unable to keep up despite the fact that the advertised bandwidth of my connection far exceeds the required bandwidth of the video. I get more stuttering videos now than I did in 1998 despite the fact that I have 2,000 times more bandwidth now than I did then. So what difference does it make if I get 10Gbps over my current 30Mbps?
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?
I thought I read somewhere that it was 10,000,000 kbps, or was it 10gbps?
Metric conversion for those who prefer simpler numbers.
Oh, and that's a furload of Libraries of Congress per time period.
Does a balcony count?
Technologically exciting, realistically irrelevant. It has become abundantly clear that the telcos do not want to upgrade their networks no matter how much the cost of doing so drops.
Range too short, higher frequency and therefore more sensitive to interference, and I doubt that is symmetrical (upload speed might be ridiculously low). Simply take the fiber to the home (FTTH) and period.
Religion: The greatest weapon of mass destruction of all time
.. there's shit tons of fiber where I live, only it's under the streets but doesn't reach premises. No incentive or obligation to hook it up to cramped four-story 19th century buildings, where most of the flats are rented.
Simply put no one will pay for doing whatever complicated digging and stuff to do in the building just so I can upgrade speed. And oh, you often have a succession of building less than five meter wide, in a one-way street.
Regular DSL speed is high. VDSL is perfectly useless : needs to be less than 1km away from the central.
The DSL qualifies as "high bandwith" and is nice, only the upload speed is 1Mbps. That's frustrating and slow, but upgrading such connections is considered a low priority. Not enough flats in the building makes it low priority for fiber deployment as well.
Whatever, I'd be happy with anything that increases the upload speed by 100x.
WhatCouldPossiblyGoWrong - as this is the first 500MHz, the top part which contains public safety frequencies and lower parts government stations. We didn't need those, right???
The 10GBASE-T IEEE 802.3an standard supports 10Gbps Ethernet up to 100 meters over shielded CAT6 or 55m over unshielded CAT6 twisted pair.
Well 10 Gbps doesn't sound so amazing, now does it?
The much better Ars Technica summary article says that yes, 30m for 10Gbps, but 1Gbps over 70m. Gigabit DSL would be a game changer.
Could they work on getting +100mbits over 2KM instead(1.2 mile).
well its nice , because they now have to compete with the cheaper huawei. And also are laying off a lot ot people
I'm not aware of asymetric Ethernet standard, for instance. Fiber to the home is basically last mile Ethernet, and in some markets where residential ISP just sell DSL service without bothering to limit speeds (and where caps are unheard of) you are really able to get a symmetric connection. Other providers may artifically limit the connection to an asymmetrical one like 100/10, 100/30 or 100/50.
Why we are now measuring thing in units we never use, bits, is pretty beyond me.
We use bytes, K bytes, M bytes, G bytes and T bytes.
Using bits with a lower case b is a byte / 8 and can be useless and misleading to the average viewer.
- Zav - Imagine a Beowulf cluster of insensitive clods...
The last mile of copper in the US is in an abysmal state. Telcos like Verizon are laying their fiber network and abandoning their low-cost copper network.
In Princeton, NJ we can barely make reliable, noise-free, voice calls over copper. T1s over copper are similarly disappointing.
I doubt pushing even higher speed data over this terrible infrastructure will result in a satisfactory experience - and the minute you need to replace a cable, why not lay fiber?
I can't even get fast speeds on dial-up since they connect from 24000-31200 even on 56k modems. :( Also, no DSL because COs are too far (over 20K ft.). :(
Ant(Dude) @ Quality Foraged Links (AQFL.net) & The Ant Farm (antfarm.ma.cx / antfarm.home.dhs.org).
ATT: But no one asks for faster speeds...
I am the unwilling control for my Origin.
Could swear 4 wires can carry Ethernet
wow, too bad the exchange box is a mile down the road
Really. How interesting. I suppose if CostCo doesn't happen to sell Curious George Takes a Shit, that means they "banned" that book too?
Get over yourself. A store choosing not to sell a book is NOT censorship. Censorship is trying to control what people read, and if it's available on Amazon, the "censorship" is obviously a horrible failure.
10 000 000 000 000 000 000 000 pico bps
will have a new pricing tier that only the .1%ers can afford. Comcast charges $249/mo for 150/20 internet. This is 67x faster so they will have to charge you 30x as much. $7500/mo anyone?
they will still manage to fuckup the implementation
What a waste of time! Just give us the damn fiber, stop worrying about our precious flowerbed and BRING FIBER TO HOME! If nothing else bring the fiber to a multipoint radio to connect to point to point (ie house rooftop to house rooftop) radios. No digging required.
The research for this technology is a waste of time. Bring Fiber To the Home and be done with it! Or at least bring fiber to multipoint radios to distribute access to rooftop point to point to point radios. No digging required!
