Sounds like Comcast is creeping to FTTH. Metro-E sounds like an expensive, inefficient way of doing it though. (Clearly working with what they have...)
Still, a Metro-E for only $300, + 500 for Fiber to your home?
$300 is a LOT of money a month, but its pretty amazing the cost can be reduced that much...I wonder how much fiber they will run for that $500 install.
If Comcast switches to IPTV (Theoretically) and devotes all channels in the system to DOCSIS, how much bandwidth could they pull off? I know the above is unlikely, but its probably cheaper than building a totally new system.
