Nanotechnology For Fiber
(old news - 08:34AM Saturday Jul 08 2006)
tags: Fiber
According to Cornell University's Chronicle Online researchers at the Cornell Nanophotonics Group have created a broadband light amplifier on a silicon chip. The photonic device replaces microscopic electric wires with light traveling through microscopic waveguides. Photonic circuits are expected to find their first applications as repeaters and routers for fiber-optic communications, where several different wavelengths are sent over a single fiber at the same time, amplifying the multiplexed traffic. Other predictions include all-optical switching, optical signal regeneration and optical sources for quantum computing.

Nice

But of course the US will be the last country to even apply this technology. Japan or Sweden will be the first to use this. 10Gb down/5Gb up for $100 per month.

Re: Nice

I would think the amplifier would have more use, critically, for that matter, not in FTTH so much as in cross country/cross water body runs.

Re: Nice

We have to RUN the fiber before we can worry about faster switching for it lol. And incumbant telecom "bankers" arent about to give us an inch of it.

Re: Nice

That's why, in many posts, I have stated that, at least for FTTH, it should all be each state's counties owned and run, and the various providers simply hook up at the COs and computers route based on some coding system to subscribers. That would give people instant ordering access to ANY provider they want, improving competition, killing the dirty monopolies, and forcing providers to improve content.

I think it should be a national initiative.

Re: Nice

At the CO's?! Why doesnt the city just directly negotiate with higher carriers! They could save a fortune buying direct from cogent rather than resold crippled trash from time warner or sbc.

I thought a massive amount of fiber was laid in the late 90's during the dotcom boom. Most of the companies have since imploded or been bought up, but the dark fiber is still there.

Re: Nice

That's all backbone though. There's no bottleneck there, it's from the pole to the home, or from the CO to the home (Depending on the age/last update of the network) where fiber needs to be laid.

Now, now... let's give credit where credit is due. America will always be first to apply the technology. After all, it was invented and first used, here. As for your prediction that Japan & Sweden will be first to commercially benefit from the technology; that's possible. However, it's really too early to tell.

Congrats to my friends at Cornell.

you only need that only if u plan on download everthing on BT

Re: Nice

Right, no one would need to be able to make multiple VOIP calls at once, while watching multiple streams of IPTV. If you're not using BT, you should be on dial-up..

Another possiblity

And, perhaps, if they are made in an integrated way, and optical processor? Hmmm... We may be getting closer. I wish I was working at that lab.

true applications

I think the idea of the article was to further reduce the size of each "fiber strand" an order (or two) of magnitude, thus fitting much more 'strands' in a typical fiber cable, thus increasing overall bandwidth of the cable and/or reducing the necessity for "amplifiers" every so many foot length before signal attenuation. This is much to do about next-generation internet backbone and underseas cabling upgrades of the 21st century more than anything. Seeing widespread use to the home? Nah, that's only when internet 1 as we know it is SCRAPPED AND ON THE ASH HEAP OF HISTORY!

Welcome to the 80's

»en.wikipedia.org/wiki/EDFA

EDFA's have been used heavily for the last 15 years. Sure this is a "on a chip" but not quite the revelation the title suggests.

quote:
The advantage this scheme offers over previous methods of light amplification is that it works over a fairly broad range of wavelengths.
EDFA's already work very well amplifying the 40 standard DWDM Lambdas. The questions is can these new devices offer the same gain with lower distortions, or higher gain with the same amount of distortion.

quote:
The process also creates a duplicate signal at a different wavelength, so the devices could be used to convert a signal from one wavelength to another.
Now that is handy, route and loseless split redundancy!

Re: Welcome to the 80's

Three atoms wide... replacing a traditional electrical grid? This is huge, on a chip or otherwise. RFI/etc will be nil, and that's just one of the minor advantages.

No leaping headlong into the 80s there.

Well this helps fuels my dream.

This would help with fueling my dreams of having all the major Local Telco's lobby the Gov, for a meajor Nation wide copper replacement with Fiber...

yeah like I said it was only a dream.

(A freakisly expensive but promising dream)
