That's also a compelling point.

It's not a simple question for sure.

The other reason I would think about GPON is that if a larger company wanted to purchase our network down the road I have to think about what THEY will prefer. They'll probably prefer PON.

Humans are horrible at assessing their own biases, but I probably have a bias towards ethernet because it's familiar. I try to bear that in mind too.

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.

PLC splitter in spice case doing full fusion splicing.

Are you using splitters in splice cases or in cross connect boxes?

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.

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.

We are walking away from them and Alphion...I think Mark's product with Zhone is different.

In light of finding out that Calix's offering is not going to be anywhere near within budget, does anyone else have any other suggestions?

I found these guys, but have never heard of them:

It looks like DASAN also has an option - I've at least heard of them:
