Re: UC San Diego Researchers Amp Up Internet Speeds
I like to consider myself pretty sharp, and a pretty quick study when tackling something new, but jeeze - more than a couple lines of this stuff goes right over my head. I understand, basically, the science at play here; travelling over long distances produces a (predictable) distortion effect in the data being transferred, and the scientists have found a way to compensate when the trasmission is made. That much actually seems pretty straightforward - indeed, the paper from last year said: "...the described [current] state of affairs is at the least surprising, considering that the nonlinear impairment... should be effectively mitigated, if not fully cancellable." As soon as we start talking about "the carrier frequency uncertainty, as well as in its stochastic variations", though, I'm pretty glad I decided not go for that doctorate.
Anyway, if I'm understanding it right, this allows more power to be sent with the data at the time of transmission (because increased power normally results in increased interference), which is what allows it to travel farther without the need for regenerators? That makes sense, but it does seem likely that we're looking at some years before that's the standard. Networks need to be rebuilt to take advantage of the lack of regenerators, right? The two ends of a given fiber link would also need to be modified to use the technology developed by the UC SD researchers once it's ready, wouldn't they? Since the University has put a patent on it, widespread adoption may be hindered - without which, this approach loses some value; transfers won't actually be that much faster unless they're moving only on these kinds of fiber links. Still, very promising and interesting. Thanks for sharing, Nathan!
