Where can I find a diagram showing components of fiber network?

I found a couple of online diagrams. My guess is that this one explains mostly what the AT&T configuration should eventually be like. I guess the install tech may have said "ONT" rather than "ONC" and I guess digging will have to be done to trace the connection route to the splitter, perhaps AKA the "node".

Hello,
 
I am a Fiber and DTV Field Manager down in the Houston area. I can clarify a bit for you. It does vary based on your location, but the general gist is the same.
 
The signal is sent from the Central Office or CO(coming from various national network centers towards the local). From there, fiber runs to several PFPs (the main box feeding the neighborhood). The chart above does not include all the individual interface points we use. The OLTs are located in the CO. 
 
The PFP is where several splitters are located. Each splitter runs up to 32 customers. The distribution side of the PFP is composed of individual fiber strands running to what we call terminals. Depending on your area, they are either buried, a pedestal in the ground, or placed on a telephone pole. We typically feed about 4 people on average from each terminal.
 
That fiber connection from there goes directly to the ONT via what we call a drop. Again, either buried or run aerial, we convert to a fiber IW if the ONT is inside, or splice to the ONT on the outside of the house. We have switched to installing inside ONTs, some people still have outside ONTs existing, but we do not install them new anymore.
 
I hope this sheds some light on your question.

As I understand it, GPON (Gigabit Passive Optical Networking) is the name of a distribution technology or system, not a location or a piece of equipment.

Thanks. Considering the configuration information that has already been provided, what schematic details might my Premiere Care rep have been referring by telling me that the fiber service in my area was "available to the node" and "available to the GPON"?

I'll tag on here because the information is interesting and we're having a problem with intermittent "Gateway Unreachable" errors.  We received a 'new' Pace 5268 router because the old one did not have an indication of service, but it did under 'old' Uverse.

The new router was installed yesterday, booted up and was working fine until just a few minutes ago when the Service light turned red and Chrome reported "Gateway Unreachable", so evidently the problem is on the AT&T side...but where?  And why doesn't my next door neighbor, also on fiber, have the same problem?  He's on 100Mb and I'm on the 1000 (960Mbps).

Puzzled.

Rob,

This is really helpful. We have a node right behind our buildings, about 20 feet away, but according to the tech, it can only feed 4 customers, so it needs an upgrade to feed more than 4. The problem is that these are new multi-unit buildings, there is only one address in the system that can get Fiber, that's based on the old address format which had Floor1, Floor 2, etc.., versus units like 1E or 1W. The question to you is how can we get ATT to come out and install an Inside Terminal so everyone get fiber. The entire zip code has Gigapower, but those new units do not. 

Also, do you have a contact for your counterpart in the Chicago area? It has been impossible to get someone to look at this, despite a million calls and requests.

Thank you. 

I hate to raise a thread from the dead, but was curious on the PFP setup for new neighborhoods if you're still around to answer. I'm curious if AT&T is still using GPON for these mass Gigapower installs, or if they've started utilizing XG-PON so the shared bandwidth doesn't get stretched too thin with massive demands like 4k (and unlimited caps for gige customers). XG-PON can coexist with GPON so I'm just wondering if AT&T is cheaping out by deploying the older systems or if they're actually utilizing newer (this decade) tech to compensate for greater demand. I'm in a brand new neighborhood so I'd be a bit piffed if all 6 phases are completed and speeds started slowing down over time. I know a nice spot to move to in Colorado if that's the case where several fiber companies are rolling out gigabit for cheaper than what I'm paying for GIgapower.

Yea that's easy enough to go look at, I was asking about beyond the house. If the cluster is in groups of 4 from the splitter what's connecting the cluster to the outside? Are we all still linked by gpon and gpon out of the neighborhood, or is it XG out? Let's say there's one "me" in each cluster of the neighborhood, I could see that being a problem in the near future and people becoming bandwidth starved. I know the guy at the end of the street uses his 1Gb as much as I do and if the above is true it'd explain why I sometimes get dips in performance at random times. He's only 2 houses away and I believe the PFP is in my front yard so we should be on the same cluster.
