Charter Node?

Click for full size
Have this in the basement of a location feeding the tv. From what i can tell the bottom device is a fiber fed node?

We currently have coax based internet at this location, but if this is charters fiber then it should be easy(meaning no construction) for them to get us fiber based internet services.

That is a node provided by your tv company with a pin to f connector.

It should not require much construction to bring you fiber internet as you already have the fiber inplace.

However they may not have enough extra fiber pairs I cannot tell how many pairs are in the cable usealy only 2 pairs will be used for foward and return signal and the rest are redundant (depending on how the system is setup). The pig tail will be from the splice enclosure to the node this usealy has 6-12 count of fiber.

The count of the incoming fiber to the splice enclosure could be any count but is labeled on the cable

IE: SM Comscope Optical Reach 6297FT - 48 CT - 2007
that is only an example of how the cable may be labeled but a close up of the cable may help us determine it

The bottom "device" is probably only a fibre splice enclosure. It probably has no active electronics.

the fiber cable it self is between 24 and 48 count fiber the black bock box is a splice case there is no electronics in side it is pressurized with nitrogen to keep humidity out of the fiber. I know this because I have done fiber installs for a cable company before

The cable coming out of the left side of the large silver box, the optical node, is the coax cable feeding your building.

The fat black cable coming out of the right end of the node, parallel to the floor, is the fiber optic cable feeding the node.

The fat back cable going down toward the floor, on the right end of the node, is the power to the node. It is coming from the power supply mounted on the wall (the box with Alpha on it).

For them to get fiber to you from the node will require more than just breaking the fibers out on your end, it would also require equipment on both ends, probably something like an Atrica switch.

Yea we heard back from charter confirming what everyone has said. I know there will be some work involved but anyone that has gotten fiber installed knows that the construction / getting it in the building is most of the battle so since we are already past that point things should be easier than normal.

Seems like a bit of a waste to run that many fibres into a building just to service a cable node.

My guess is it would be more like 2-3 pairs (if not a single pair), which seems a hell of a lot more sensible, and still allows them to install additional services into the building.

Keeping in mind that it is possible to run duplex communications over a single fibre, so they can get increased mileage out of their installation.

And dont forget WDM which allows even further mileage.

Is that a Motorola 870MHz node?

It looks like an SA6940 node.

Oh your right. That's what the node looks like serving my area. Also Comcast in Pottstown and Charter in Springfield, LA also have the same style nodes.

All are 750 MHz systems I believe.

It's hard to tell by just seeing the housing, but it may be 750Mhz.

Comcast here uses Harmonic Lightwaves in Springfield, MA. Charter in Chicopee MA seems to be using the same Harmonic nodes 3844 scalables (870-1Ghz).

I agree that it's hard to tell the bandwidth by the housing, but the SA6940 looks EXACTLY like that and according to Cisco's product catalog they only come in 870 MHz. They still have some archived 750 MHz gear in the SA catalog but the housings are different looking.

Service Electric Cable around here are using C-Cor M4000(NQ57)
870MHz and NT25 Nodes.

here is a picture of a node at another site. This one is serviced by brighthouse and the fiber provides us 10mbit metro-e and the node gives us cable tv.

yea i do remember it saying SA on it when i looked at it while i was there.

actually looks like i took a picture and forgot about it

Thats cool how they put a node right in the building.

Were looking at possibly expanding our T1 service to something with a little more oomph. Metro Ethernet from cable sounds like it has potential to be a good deal. Not sure if were going to be able to go that route or not. Most likely a little later this year we'll get some bids from a few providers.

Brighthouse had a fiber vault within 200 feet of our site. They didnt have coax nearby, this was in Indianapolis, IN which has a few different cable mso's. They wanted to provide us cable tv service (this is a hotel so it was worth the investment for them) so it was pretty much the only option to stick the node in the building.

Attached is the final cable amp they left us with. The first one they put in was an outdoor model and made a very loud buzzing noise. We bitched at them and they brought this one in.

Oh that's the power supply for the node. Outside if you see those green or grey boxes on poles (sometimes with the words Alpha or Lectro on them), one of these are inside it, along with batteries. Buzzing noise could of been from a really noisy transformer in the last unit. You really don't need battery backups on that unit (and you don't appear to have any) as the node serves just that building and not a whole neighborhood.

Those SA Gainmaker 860 MHz nodes are really nice. Much smaller than the SA node in the original post. That node will last you many years of trouble free operation.

I see comcast is your isp, i honestly havent had much luck with them. Only place so far i am making progress with them is in houston, which happens to be a market that used to be time warner and comcast bought it out. Hopefully your area may be reasonable, but most comcast areas ive checked into either dont offer metro-e at all or the price point is insane.
