Flexible Optic Fiber Promises Cheaper Last Mile
bn0p writes "Ars Technica has an article on a Korean company that has developed a low-cost, flexible, plastic optical fiber that could bring cheaper 2.5 Gbps connections to homes and apartments. While not as fast as glass fiber, it is significantly faster than copper. In related news, Corning recently announced a flexible glass fiber that can be bent repeatedly without losing signal strength. The Corning fiber incorporates nanostructures in the cladding of the fiber that act as 'light guardrails' to keep the light in the fiber. The glass fiber could be as much as four times faster than plastic fiber. Neither fiber is available commercially yet, but both should help with the last mile problem when they are deployed."
If you don't have other reasons to dig trenches etc, then wireless is typically far cheaper because the installation costs are zero.
Engineering is the art of compromise.
Flexible fiber optic may be a great solution for our broadband needs, but their true calling is now twenty years passed.
The plastic one would be great in the last 100 feet (33 meters). It would be nice to run fiber through the home, as well as a cat 5. The cat 5 can carry power (POE). But if that plastic can carry 2.5G AND is easy AND cheap to install, it will quickly make waves in the housing industry.
I prefer the "u" in honour as it seems to be missing these days.
Not in the United States anyway, our "last mile problem" has a lot more to do with entrenched telecom and cable companies with regional monopolies than any sort of fiber bendiness.
Flexible fiber optics would do wonders for apartment buildings and its residents. With cable going digital in 2009, this would be very important. BTW - check out the back of your plates - it may be made by Corning as well (mine is).
I don't think the cost of the actual cable will change the equation very much. I've been out of it for more than ten years, but even then you could get fiber for less than $1/foot - I assume it's even cheaper now. I have to believe most of the cost lies in planning, getting permits, and digging trenches.
Yes, we can get fibres to house really soon. Also I saw a nice 2D filter which can be used for Multiplexing fibre users in a single channel (Optical-CDMA).
But.. lets say all these goes really well... what about
1. Internet infrastructure... we here many people saying it will meltdown really soon. So what we really need is, upgrading the infrastructure/backbone of internet. I guess, still we can survive with last mile copper network with ADSL.
2. Regardles how much bandwidth you get, if your PC can't handle that bandwidth.. then all the killer apps won't be exciting.
I thing it is worth while to read journal papers written by Klienrock, he explains some of the things we really overlook in designing/building huge data networks.
cheaper than the one I have now? sweet!
Seeing the "vaporware" tag on this article prompted me to post... I can confirm first-hand that the Corning, Inc. flexible glass fiber is not vaporware. I realize posting as AC doesn't help me credibility, but I assure you it is real. Whether providers/installers/manufacturers pick it up is another issue entirely...
What I don't get is why we seemingly refuse to invest for the long-term in the United States. Sure, some companies do, generally the smarter ones. But when it comes to public infrastructure, politicians haven't found a way to inform the public that by spending 2x as much now, we're saving 20x as much over the next n years.
I know that technology evolves at a rapid rate, but if we invest more money now and use the same amount of energy* now (compared to doing investing less money and the same amount of energy), then we can use the energy that's left over from not having to double our efforts next year for other causes.
*energy here is refering to human capital.
Is the cost of the cable really that relevant? I thought it was the cost of installing the cable that was the major stumbling block.
:%s:work:/.:g
The research group is mentioned to be in "Korea Institute of Science and Technology", which is better known as KIST here in Korea, isn't a company. It is a government research agency.
The abysmal state of what passes for "broadband" in the US has nothing to do with a lack of network technology for connecting the last mile.
This is a layer 1 solution to a layer 8 and 9 problem.
Distorting information became so much easier.
Most people don't get why the integral of "e to the x" is so funny. Most math majors don't have a sense of humor.
My understanding is that the last mile problem is all to do with the cost of laying wire not the cost of the wire itself. Also, if everybody has gigabit connections the cable provider is going to have to invest in some very serious switching and upstream connections. In short fixing the last mile will probably only expose problems up stream.
I keep wondering about god playing dice and quantum entanglement. Currently, the labs are stuck at a few miles. But if they can up the range and speed would this not be a better solution. A cable of infinite length that is also secure that you can give to any ISP. ISP would be an open market and speeds would go up as costs went down. No need for cable/wireless so zero installation costs.
So is QE going to happen or is it just my poor grasp of the subject matter?
It's not the cable itself that's expensive, it's laying it.

What's wrong with copper? I'd freakin love even 100 MBPS at my house! That's like a minute and a half for a good quality DVD movie instead of hours. And copper can do gigabit so geeze. They just need more of it and better network switches and routers instead of cheaping out and giving crap service to everyone to save a buck

There's a reasonable chance wireless will eventually solve many of the last mile problems; I recently cancelled Millennium Cable in Seattle for ClearWire instead. Right now it isn't available everywhere and the service isn't particularly fast by fiber standards, as its 1.5 down /756 (I think) up. But if the technology improves faster than fiber can be rolled out we might not care by the time 2011 rolls around.
Using quantum interactions to transmit information also requires you to transmit a signal the old fashion way. This is essentially what prevents you from exceeding the speed of light. You would also need a way to distribute the entangled particles ( each pair can be used only once ). The advantage of quantum entanglement is completely down to its ability to transfer quantum states ( no set of classical information can completely describe a quantum mechanical system ) and it's security against eavesdropping and brute force attacks
Now, contrary to popular belief a man in the middle attack is still possible. That you are exchanging pairs of entangled particles rather than exchanging large integers doesn't matter. You still have to be careful about who you accept keys ( or particles ) from.
The article writers and poster have no idea what they are talking about. Unfortunately most of us fiber scientists & engineers got laid off during the tech crash.
Plastic fiber has been around for decades. It is cheap. The problem with plastic fiber is that your signal won't go as far as with a glass fiber. However, for "last-mile" use, you don't need to worry about signal loss since you aren't going very far. The big cost in "last-mile" is digging up the ground and putting in the cable/conduit/fiber. The cost of the fiber is negligible compared to getting right-of-way and the cost of labor.
The cost of the fiber is so low, that normally when you dig up the ground to put in fiber, you put in lots & lots of fiber (since it is so cheap), just in case you need it in the future. This is called dark fiber, and there are millions of miles of dark fiber all over North America (from the tech boom) that used to belong to dotcom upstarts & their venture capitalists.
And as for bending fiber, you can always bend fiber. When you make very thin glass or plastic fibers for optical purposes, they are flexible. Has everything been running in straight lines?! Idiots.
Now, there is minimum bend radius for fiber, and if you bend your fiber beyond that, then you start to get some loss. Normally this isn't a problem, and you can't bend the fiber that far anyway - fiber has a cladding & outer sheath (which varies depending on the application indoor/buried/underwater), which limits the amount of bend, preventing bend loss.

They should run many in parallel right from the outset to, say, quadruple the throughput. This is because although the investment will be much larger in the short run, in the long run, it will save money, since it will put off the need to upgrade to yet higher throughput systems, which will save in switching costs. Not to mention that installation of the cable is probably more expensive than the cable itself.
...of ClearWire LLC. I can only wish you the best of luck! While I have heard that Seattle has seen substantially better speeds then what I ever saw, I still feel for you. You see I live outside of Boise, Idaho. 3rd largest city in the United States' Pacific Northwest. And well... shucks. Let's just say the first 3 months were great....
I'm sick of following my dreams. I'm just going to ask where they're goin' and hook up with 'em later.
Corning (division of Pyrex and one of the main glass fiber optic manufacturers) already announced their flexible glass fiber optic shielded with nanostructures back in July. http://www.corning.com/media_center/press_releases/2007/2007072301.aspx
It is never going to happen. I live less than 20 miles from a town of over 300000 people and they won't even lay coax out here. (ADSL is useless with its extremely limited range)
Last mile my ass. Wireless and satellite are useless for gaming. Good old fashioned analog modems connecting at 28.8 Kbps is the best internet connection that most of North America will ever see. That is the fact of the matter.
The focus needs to be on elimination of high bandwidth crap that makes the internet nearly unusable for the majority of its users. Unfortunately, few web developers can grasp this concept and are losing out on huge sections of the market.
In addition, I have been using fiber optic connections between analytical instruments with a bending radius of 5.3 cm for decades, I can't see the need for less than that. If you need to bend fiber connections more sharply than that (especially in scale of miles), then you have serious design issues. Fiber has been very flexible for ages, this is totally bogus, not to mention totally unnecessary, and totally moot, as it will never happen anyway and fiber flexibilty has nothing to do with it.
if I had my preference I would take wired over wireless anyday
Just as with phone service, I only have a cellphone, I'd take wireless over wired. That way I can take it with me. I've got cable now but given the chance, if my ISP were to offer broadband wireless, I'd take that so long as it didn't cost too much. Of course I could make more use of it than some others would. Next year I hope to get into photography and with WiMax or some other wireless broadband using a Digital SLR and my laptop I could upload photos to a server while out in the field.

I wonder where they pull the 2,5G upper limit number? In fibre, the most important properties are attenuation (at specific wavelengths) and dispersion. Both properties determine basically, what's the distance you can shine the light through the cable. Current G... whatever standard fibres have quite specific attenuation: very low at 1500nm area and somewhat less lower at 1300nm. Respectively long-haul and short-haul. Rest of the waveleghts are basically unusable.
Using DWDM one can multiplex many wavelengths into a single pair of fibre, delivering hundreds of Gbits over long distances. This is where the dispersion comes into a play - different wavelengths travel at different speeds.
Why bother digging up all those trenches when you can keep the copper and get your 10G, so they say.
so, just how bendable are these new cables compared to old ones? Can't find any numbers on that in the article. Here in Norway, they have installed fiber into private homes for a few years now. The outdoor cable can bend radius of 20cm (8in), and once the thick plastic shell is peeled off for indoor use it can handle 2-3cm (1in) bends. I haven't found any theoretical speed limits for the cables yet, but they say it should be good enough for decades. (At the moment they only offer speeds up to 50/25mbit, but that seems to be more because they don't want their backbones breaking under the insane P2P load... And the router/brigde seems to be only 100mbit on the LAN plug)

I work with plastic fiber every single day. You can bend it around your pinky and still get 4Gb/s or even 10Gb/s out of it. For short-haul distances, 300m or less, it works just fine. Is this article from 10 years ago? For some reason, this is reminding me of how Microsoft touted shortcuts as something new when UNIX had symlinks (and got them right) decades before.

Blagh, do tell where to pick this up as well.
First, I remind you of that 640K memory is ENOUGH for anybody. The simple fact is that if a couple of Gigs were available in most homes, then the apps would show up. The real advantage of using plastic fiber is that it bends easily and will almost certainly be cheaper than copper. Currently, copper is shooting up in price and is going to go MUCH higher in the coming year (china is trying to corner the market on it, and the dollar is plummeting, while the only new find of it was in tibet). So all that is needed is to make the connection cheap. Well, this is plastic, not glass. Almost certainly SOMEBODY is going to make cheap connectors. I would also guess that nics and switchs would plummet in prices once fiber goes into homes.
I prefer the "u" in honour as it seems to be missing these days.
i dont know too much about the difference between civvy fiber and the milspec stuff, but i know ive tied knots in the stuff i trained with and had no real signal loss. fusion splicing has negligible losses too, and its just a button push from two separate fibers to flawless junction. so really, whats the deal? tactical fiber isnt that hard to handle, its just bigger.
Cheaper fiber, thats great. However I expect to see it rolled out in my area (Milwaukee) around ... ohhhh I don't know - maybe the day after pigs fly? The sad reality is that the telco's will continue to squeeze every last day out of the existing rotting copper network to increase their profits. Then on the day they just can't get any more blood from the turnip they will jack service prices in the name of "upgrading and expanding their infastructure".
So, just as cable responds to current fiber installations with DOCSIS 3, fiber leaps ahead again. They're just making it easier and easier to get rid of Comcast.
"It's the height of ridiculousness to say for those 9 lines you get hundreds of millions."
Bear in mind the construction value to these innovations, too. For example, aesthetics is normally the primary driver in new office constructions and cabling has to work around it. Not a big deal except in situations like the Empire State Building where the ceiling heights are already low, Washington DC's codes restricting building heights, and other extenuating but not too uncommon scenarios where architects have to push the limits to "create space." This leaves us with very little room to work with just about everywhere, some areas that are sheet rocked over or otherwise completely inaccessible and other cabling challenges necessitating expensive EMT conduit. The tighter the space the more aesthetics drive the effort leaving little functional room thus increasing EMT conduit and other cabling costs. Granted some of it's needed anyway to protect cabling but others are to address the propensity for fibre to be pushed passed its restrictive bend limits. When dealing with spaces where the square footage is in the 5 figure area the savings are in the 6 figures!
Also, it allows us now to even consider fibre in these tight spaces as until now our basic approach has been to only consider fibre when the connection point distances warrant it.
That's just my POV... no more, no less.
Recently announced? I've had the announcement about Cornings new fiber in my journal since August. See for yourself. It was never selected so I finally put it up so you folks could be informed.
I guess I shouldn't be too harsh on the folks running this site despite the dupes as they seem to have gotten around to fixing their mod point distribution system.

Does anybody have any idea why HDMI cables are copper, when with the bandwidths involved, you would think that a simple optical cable would be much better? When you're talking distances of a couple of meters max, even plastic kite line would probably work, so why to they keep making short cables out of copper? Even my 10 year old MiniDisc player supports an optical connection. If they'd made HDMI optical, then they probably wouldn't have had to make a new format of cable EVER.
