Extreme 305

Any idea how this will work in cities where they don't have underground conduit and only overhead wires for each block in alleys? I'm guessing it will be restricted to the 10 - 15 houses in the alley with the node.

This being important as their competitive markets (FiOS) are almost all in cities.

*Where and when will you be offering Extreme 305 Internet Service?

** The Extreme 305 Internet Service will be launched across our Northeast division in major markets, including Boston, Hartford, Philadelphia, Pittsburgh, Harrisburg, Wilmington, Baltimore, Washington, D.C., Richmond, and New Jersey. Currently, we’re launching these offerings in this set of initial markets and will be determining future roll-out plans at a later date.

Eligibility:
*Customer must be Metro-E serviceable. Then, fiber site survey must be completed prior to installation to qualify the home/address.

*The site must meet the following criteria:

*Single Dwelling Unit

*Located less than 1/3 of a mile from Fiber Access Node

*Aerial fiber build only (Aerial or Underground drop)

*Serviced by Metro-E capable Head-end (SUR/1G-E Port Available)

Additional Eligibility Guidelines:

*Dwelling with aerial or underground service access must be within 150 feet of the Comcast infrastructure and:

*Either have no obstructions such as hardscaping, paved or unpaved driveways, sidewalks or retaining walls
- Or -

*If these obstructions exist, intact underground conduit readily available for Comcast use must already be in place

Considering that most areas are getting their B1 Basic TV cut, this is going to free up spectrum and service CAN be done with 12-16 256QAM channel modems. With a CMTS line card upgrade and new modems, this can be done over existing COAX. May be different deployment per area.

so does it wind up being a dedicated pair (2 strands) of fiber from the customer back to the CMTS?

I know that the build out they did out here (yes, this is west coast, not eligible for extreme 305 right now.. thats besides the point), there is a fiber splice case near every node.. but judging by the size of the fiber cable they ran, it cant be more than 96-strand fiber to the node (and that's being extremely generous, considering the small splice cases i see).

So how many customers, on average, would comcast be able to serve the extreme 305? is it first-come first-serve until they run out of free fiber?

Obviously i'm thinking about this in the terms that each endpoint requires a pair of fiber (you know, your standard networking layout.. switchrouter, etc)

there is a splice enclosure at every node, no matter where you are located....if there isnt a contractor needs to be fired. how else you going to splice into the main fiber run?

also you dont need separate fiber back to the head end, you can just mux the wavelengths together.

I'm better than you!

so this sounds like a FTTH setup, correct? if a lot of people on a given node sign up, there is the possibility of comcast having to size up the splice case at the node to handle the growth?

or, like in my area i know of a couple businesses that have metro-e (100Mbps symmetric...my wife works for said business) off the splice case off my node. my node is about a mile (cable length) from my house, but these businesses that had fiber ran to them from comcast are much closer (from the splice case at the node), would comcast build from me back to the to the node (mile away) or from me back to the business they already ran fiber to (less than 1/2 mile away...)

wo fiber dem pings are making me wet, do want.

however, they should be able to do 300 megabits over coax no?

reply to gar187er
Figured each fiber strand can handle 1Gbps each way with ease so 1 strand should be more than good enough per customer.

reply to whfsdude
Coax can do higher channel bonding, it's just that the equipment isn't ready nor reliable.

Metro-E can reach 10Gbps for business customers. Comcast could rely on the Ethernet solution for higher speeds.

reply to Beaverbob140
Is it a requirement to use the Netgear R6300?

It's probably configured with a custom firmware since it's Metro-E they are doing. It would be doing the job of a Cisco router or SMG that they give out now to static customers to handle your static routing tables and who knows what else.

But any common router can be statically set too though. I just hope its not mandatory 'cause Comcast and Netgear really haven't had that good a track record this year.

My bet is that Comcast hands out DHCP upstream of their CMTS, such that they can still hand out a DHCP address to anyone on 300/75, with a standard router (behind a media converter). Nothing different than with a cable modem, except the interface is different.

anyone else think it's just weird to hear the word comcast and fiber? Well they needed more fiber in their diet

I'd love 305, and I'm within a half mile of our Node (it's between two poles on Vineyard Oaks Dr), but not for 300 bucks, are they kidding? The cable, power and telephone lines run to the corner of Vineyard Oaks Dr and Forsythe Dr, then drop underground at that spot as our development (Forsythe Village) has all underground utilities. This is a very rural area (Mendocino County, NW CA), so I doubt we'll even see this anytime soon.
