I have to disagree, considering the amount of people I've had to convice that this really is a single 50GHz wave using 40G per second over DWDM system designed for 10G and that it was router "LC - optical amplification - LC"

Well yes, the technology is quite cool, I'm not debating that. The fact that it works at his mothers house (residential) doesn't really have any significance. I don't think you have anyone out there debating against caping out the upper limits of bandwidth on what we can get over a single strand of glass.

I look at this article and say "so what". Now you've gotten the packets to the house. Now what? Wait 10, 15 or 20 years while companies try to find ways to get content do you? 1500 HD channels, thats a lot of TV sets. You can have all the bandwidth you want, but but until there an actual use for 40Gbps at the home all you're going to have is the worlds fastest BitTorrent or on net porn PPV network.

Uncompressed HD TV (typically 1.54 Gbps / channel) comes to mind, for which there are applications, albeit typically not residential so far. See, e.g., http://www.gloriad-kr.org/hdtv/ http://ultragrid.east.isi.edu/2005-02-APAN.pdf Regards Marshall

How practical is it really also that you need CRS-1 at the residence for this. I agree with Sean. Since for most people the line card alone costs more than the house. :-)
