10Gbits/sec li-fi - Shock

I am curious as to what the point is having that high of local data transfer capacity is anyway?

None of my computers have that fast of internal data transfer capabilities to or from the hard drives or main RAM as is. My biggest and fastest 1 TB hard drives might hit 250 meg peak.

So what do I do with the other 9.75 Gb of bandwidth?

More folk can get broadband service at the same time with unnoticeable contention related speed degradation.

Cut the grass with it?

Internal data transfers are largely parallel, and on-air transmission is serial, mostly, so there is a scaling to the actual rate of transfer if you compare the two environments.

tcmtech, the same thing was said about fiber optic transmissions. This technology could be used for internet back bones at first. Eventually it might reach personal computers.

Pure transfer is great...but if the programmers cannot match a protocol to it and stop jamming all of that extra meta-nonsense into it...we can actually transfer useful data.

One could turn their entire home into a quantum CPU...talk about immersing yourself into virtual reality!

I genuinely think that's really nifty. Like others, I'm not sure of the need for speed for speed's sake - but the idea of re-inventing FDM for optical comms is ingenious! It's one of those concepts thats so simple that you wish you'd thought of it yourself...

Presumably the main challenge is getting multiple light sources to fire concentrically down a single fibre - I suppose it's all done with mirrors (maybe a little smoke also).

I don't see why you'd be restricited to only 3 wavelengths either. It seems that you'd be better able to optimise the fiber the closer in wavelength the light sources where, but that sepperating them at the Rx end would become harder. Just the same tradeoffs you get with radio transmission or FDM over copper I suppose.

Anyone know of a more technical article on this?

All you have described has been available off the shelf for some time now.

The F (frequency) has been replaced with a W (wavelength)

The excellent references at the end will give some insight into the current state of the art with more technical descriptions or you can Google some other WDM info yourself. There are videos and all sorts of self learning opportunities on the interweb.
