Free Bandwidth?

by Steve Gibson, Jun 30, 1999 10:11am PDT

Well this isnt exactly something I expected anyone to be saying. According to this ZDNet article the "experts" are predicting the possibility of bandwidth becoming free in the future. Check this stuff out:

The possibility that bandwidth could become free is based on the exponential growth in capacity on communications networks, being driven by technologies that allow more streams of light to be fit onto an existing pair of fibers, which push trillions of bits of data through routers every second and switch data more intelligently between interconnected networks.
I thought were were going down the tubes and running out of IP addresses and we were all gonna die with the whole Y2K thing though?

  • Actually, it\'s true about the \'more streams of light\' fitting on one fiber. That is true, which I can safely verify since I work in R&D in the fiber industry, doing just this. Without getting into the nitty gritty, (and thus breaking confidentiality agreements), there are marketable developments in 40 channels down one fiber, with research and testing in 80 and 160 channels down a single fiber. This is a far cry from a single fiber handling a single channel back in the \'old days\' (oh so long ago <g>), so essentially communications companies are getting massive increases of bandwidth without having to lay any more fiber. Now this is not an infinite process, since there are only certain ranges of wavelengths of light that can travel down the fiber without losses (other wavelengths, or \'colors\' tend to dissipate steeply and can\'t travel far), so the actual usable wavelengths is quite finite, and the trick is to cram many channels into this finite area without them overlapping. Now this is fairly successful, with tricks to reduce wavelength shifts, and dispersions, but I highly doubt that bandwidth will be \'free\'. Companies will always charge for this service, but it will probably continue as it has in the past - today 5Mbps costs under $100 most anywhere in North America (and much cheaper where I live :)), where 10 years ago, that kind of bit rate cost an arm and a leg. Point is, sure our bandwidth will go up quite drastically sometime in the future, but you\'ll also have to pay for it. ZDNet is just full of hype, apparently. Bad journalism, IMO, since they forgot that this IS a capitalist society :).
