re: Comcast Gives FTTH a Shot

Interestingly, using different (actually complementary) technology, Comcast is offering a tier that would be exactly in line with an 8 down, 4 up DOCSIS 3.0 configuration, which I think is quickly becoming the standard until chips and gear for 16 or 24 bonded channels comes on line. So, regardless of the technology, Comcast could offer the same top tier to every market.

So apart from the Netgear 6300 in the home, the network interface to the residence is what, just a media converter? Any talk of EPON here?

Off-hand, I don't know much about the network interface in this instance and how it's similar or different than what Comcast's using to bring MetroE to biz customers (anyone from Comcast care to confirm?). They didn't mention EPON specifically in the context of this new residential MetroE tier, but that's the approach a lot of the cable guys have been taking with their carrier Ethernet/fiber deployments, no?

It certainly does, but i wonder if the headroom in 8x4 is big enough to support a product that could be advertised as 300Mbit/s down... maybe it's too tight, meaning that they'd have to look at 16x4 or 24x8.  But this near-term approach seems to make some business sense... use existing fiber and the MetroE platform for one-off deployments as you figure out the demand, then spend more building up more Docsis capacity once there's a broader need to support those bigger broadband tiers... or perhaps when they're ready to employ a full IP video simulcast.  Makes no sense to add all that capacity across the board in a system if it only benefits a sliver of the customer base.  JB

And no 'fiberhoods,' I gather.

As a quick update, there's no EPON involved in this; it's all point-to-point. JB
