If you payed attention to the internet scenes, you know that Google was testing out its new fiber optic network in Kansas, but this tops that over 10s of 20s and 30s of times. If you happen to live in Germany, all techies might start drooling right now. Part of Deutsche Telekom's OSIRIS (Optically Supported UP Router Interfaces) project, the telco's T-Labs team managed to successfully transfer data "over a single optical fiber wavelength channel" from Berlin to Hanover and back at speeds of up to 512Gbps -- that's over half a terabit. Now I know that it might seem mind boggling when you think of what you would actually do with all that bandwidth (maybe to catch up on uploading all your files to Microsoft's virtual hard drive?), but this real world experiment shows that network operators will need to keep up with the growing demand for bandwidth, and with this it would drastically increase their network's compacity.
As for any actual implementation of the next-gen tech, well, the good news is that a costly and lengthy cable deployment won't be necessary; all that's required to get these state-of-the-art dumb pipes up and running is some newfangled terminal equipment.
Don't get your hopes up, though. Tech like this might take light years to reach.
