Chris,
You can do very creative things with splitters. I just finished designing service to 64 lots down a 4.5 mile dirt road. We didn't want to spend a bunch of money being there are only about 20 built house right now, but we wanted to make sure we were able to get everyone as they build in the future. Using a combination of 1x4 and 1x2 splitters, we were able to design this on a 12 fiber drop cable.

You have to change the splitter value as you go down the road. First few handhole might be a 5% the step to 10% Etc. I can usually run out about 12-15 handhole with various mix of mostly 2 and 4 cust per HH, if you are starting further from the cabinet, that hurts a bit of course. Just set up a spreadsheet and play with it.

There's insertion loss at each splitter too. How may of the 10/90 splitters can you put inline before you get too low on light?
Class B or class C optics?

Yes, i think its a beautiful fit for lower density rural where you have long linear roads. We do have some areas with 5 or less houses per mile too.
The first splitter is a 1x2 FBT (fused biconal taper) those can be made in any split ratio I think they vary the angle that the fibers meet. They are common offered in "windowed" version that only pass typical GPON wavelengths, but we custom ordered full bandwidth ones for future 10G PON techs.
Then the output of that FBT can go right to a drop or to a second "normal" PLC splitter to serve multiple drops.
We did about 12 miles with this method this year, maybe 80 or so handhole with this splitter method, end of the run is about 10 miles from the cabinet.

Yup that's a thing. That was actually my plan "A", except where he's got 30-40 houses in 2 miles I've got 5-10.
I think PLC splitters are always even, and the other type which I can't remember the name of can be uneven.
In coax they call that a "tap", but in fiber it's called a "coupler", and the thing everybody is calling a coupler is a "mating sleeve".

Interesting, so you have splitters that divide light unevenly? Or am I misunderstanding you?
On another note, I wonder if anyone has compared the ZTE GPON stuff with Ubiquiti's offering...

We splice in a uneven ratio 1x2 feeding a 1xN PLC to fees drops at that splice point. So it might look like a 10/90 with the 10% into the 1x4 and 90% continuing down the road on the same strand. Troubleshooting can be tricky, we test light as we splice to verify everything. The benefit is I can pass 2 miles of road, 30-40 houses using one strand on a 12ct mainline and still have 11 unused strands at the end to keep going.

Tapped trunk, meaning you use 1x2 splitters at each drop? I've been considering doing this, but troubleshooting, should any problem(s) arise, seems like a nightmare.

With some very appreciated help from Gerard myself and another Michigan ISP have deployed this ZTE equipment and Gerards description is accurate. The only issue we have found is some Wi-Fi bugs in the F660 ONU we went with, if you require a customer owned router or provide a different router that solves the problem.
Our long term plan for that is to switch to a SmartRG GPON res gateway when they are available in a couple months. All in one unit with 4x4 AC wifi and voip.
We also deployed a tapped trunk splitting layout which has saved us a lot of money on strand count in our low density rural areas.

Chuck,
Yeah, We have 6 OLT's and a few hundred ONU's online. I know of several other operators using the same setup now too.
It's stable and just works. The OLT hardware feels solid and quality made unlike some of the other 1U OLT's we've tried.
You can even get an outdoor cabinet made for them for about $1500 shipped. I can't find the ZTE link right now, but it is very similar to this Huawei version. https://www.alibaba.com/product-detail/Original-Huawei-MA5608T-ZTE-C320-Outdoors_60442562681.html?spm=a2700.7724838.2017115.1.2d7a50d9frcsQx

Here's some pricing based on Chinese ZTE with no real support.
ZTE F601 Indoor ONU 1 GE port. $24 http://sweetplaza.com/zte-gpon-terminal-ont-zxa10-f601-or-zxhn-f601-ftth-or-ftto-gpon-onu-with-one-ethernet-port-smaller-size_p1013.html

Chinese Splice on connector $0.80 http://sweetplaza.com/c/connector_0391
30M Armored simplex pigtail $9.66 from FS https://www.fs.com/products/20745.html
20M $7.66
10M $5.66
Wall Mount MultiLink/Tii Outdoor NID - $15 (I don't have link)
ZTE C320 OLT 16 ports of gpon with class c+ optics. $2200 $2200/16/32=$4.30/per customer at 100% utilization..
Add another 16 ports with optics for only $590. that's 32*32=1024 customers potentially. $2.75/per customer at 100% util.
32 port rackmount splitter. $84 https://www.fs.com/products/11948.html
32 port bare splitter for splice case $14 https://www.fs.com/products/11528.html
8 port bare splitter for splice case $5
None of that includes shipping or import duties/fees. So figure in a few hundred $$$ for shipping/import fees.
Even if you only put 8 people per OLT port that's $2800/32/8=$11 per customer. + $1 per port on a 1x8 PLC + $15 for NID + $29 for ONT with POTS + $10 for 30M pigtail. = ~$65/customer all in for gpon with 8 customers per port.
You can use www.SmartOLT.com for web based OLT/ONU management/monitoring (tell Adrian I sent you for a discount)
I prefer using GPON for the management capabilities. You can always overlay 10GPON on top of your regular GPON network when the time comes to upgrade. Just add/change the card in the OLT and add a 2x1 splitter to combine both OLT ports into the single fiber. Since they use different wavelengths they will coexist over the same fiber. Just install new ONT's.

Chuck,
Dug up some of my costs on the GPON. One port with a C+ class laser and a 1x32 splitter cost me about $1000.
So if I stick with my 50% utilization numbers, that gets me about $62 per user. Plus an indoor ONT gets me about $200-$225 per customer for electronics. As I increase my utilization, the numbers get better. But, we are only talking a different in a few months on the ROI. Remember we are debating fiber. I have ONT's out there over 72 months old. I'm sure Chuck has some at least 2 or 3 years older than that. I don't plan on any type of major upgrade for several years.
But I must stress there is no right answer. AE vs GPON. You need to make sure you fully understand both options before making a decision. Not to mention, you can run both. We are setup to do AE, We currently have 2 customers on the AE side for various reasons vs 2500 on the GPON side.

When doing full throttle Calix GPON we have about $570 invested in cpe electronics, splitter, ont/olt/onu etc. Everything but fiber and outdoor cabinets.
When doing active Ethernet you can come in closer to $100 per customer.
For non regulated greenfield, I am having a hard time convincing myself to do PON.

Adam,
There are some ranging things you have to consider. "The requirement
when deploying ONTs are the maximum distance between two ONTs cannot
exceed 20Km."
The way we have done this is to reuse fibers as we travel down long stretches of roads between neighborhoods.
We will deploy a 1x32 splitter in the field. We will splice that into the last 3 ribbons/tubes of our fiber. Example, if we were using a 144 count cable, ribbons 10-12 will be spliced into. After a few miles depending on density or distance, we will splice in another 1x32 splitter to ribbons 10-12. We just keep doing this until we run out of light budget.
We build to the lots passed, so we are not trying to optimize max usage per port. Currently, we average about 50% utilization on our ports.

Maybe I need to review the math.
I was figuring on several small splitters along the route. I didn't compare to a 1x32 in the cabinet because I figured if I brought every fiber back to the cabinet then I didn't save anything versus ethernet.

Adam,
How far are you going? We are pushing almost 20 miles on a 1x32 split. Are you using one 1x32 or multiple smaller splitters?

I'm looking at rural areas (like a few houses per mile). As I'm looking at hypothetical power budgets for PON, I'm finding that if I run the line down the road and put splitters on the pole I can split 5-6 times and then I'm getting too low on db to keep going down the road. At 5 or so houses per port, a 1U, 8 port ONT is no denser than a 1U switch.
Your stated reasons for PON are all correct. The numbers just aren't seeming to work out for me.
I also figure if I install enough fibers for AE, I can still switch to PON some day if I want to.
We would never max out the PON port, but looking back on the past 15 years of growth in consumption I wonder if I should ever say "never". In AE I can put 100Gig in every house if I have to. I'll "never" have to do that as far as I can imagine, but my imagination could be limited.

A few reasons...
Port cost is still fairly high.
More splicing.
More fiber required.
Larger chassis required.
More power required.
More battery backup required.
Consumers not even close to using up 1-2 generations back of PON capacity in most places.
