Re: But if the Network was so congested.....
said by rradina:That's true. But they'd have to power the coax transmission gear both at the pole, and also at the side of the house. Why power two pieces of equipment when you can power just one?
If they have fiber, I'm shocked that it's FTTH and not FTTC. Short run coax has tremendous bandwidth capabilities -- especially when it's dedicated to a single premises. Heck, I'd guess with the right engineering and hardware, 10Gbps over 600' runs wouldn't be out of the question.
Now, I am kind of shocked that they're willing to dig a trench to replace the underground drop to the house. Considering that this is already a limited deployment -- limited to houses within 1/3 mile of the node, with aerial infrastructure to the curb -- why not also limit eligibility to locations that have aerial drops to the house?
It's probably a consequence of the fact that this is designed to compete against FiOS. Since FiOS is willing to dig a trench, then so is Comcast.
Could the CPE device provide power back to the pole device? Of course this assumes the device on/in the pole/pedestal is per customer. A multi-drop device powered by a one customer's equipment would kill all the drops if they go on vacation and unplug stuff.
I was reading through the thread in the Comcast forum that discussed the approach and one post claimed it might be also be DOCSIS, depending on the area.
