The WAN side of an OLT is a L2/L3 switch; the PON side is the G.984 and/or
Active E portion of the technology.

So it's really just a matter of how you're deploying. I wouldn't have an
active cabinet everywhere I would put a splitter.

Switches take cabinets and power. Splitters do not.

Yes and no. Pretty much the same amount of fiber depending on where you locate
the splitters or switches. On AE you battery back the switch. On GPON you
battery back the OLT/OIM. At the remote cabinet, you either have a cheap
switch and SFPs.-or-You have an expensive OLT/OIM and splitter. From: Josh

Years ago, there was a break even point on active vs PON. If you had 16 or
more in an area that could take a PON it was worth doing the PON.
But that was comparing Calix AE vs Calix PON. If you do AE like Sterling I
don't think PON is ever cost effective compared to Calix PON.
With PON you still have to have a drop to each home. The cost of the cable is
in the placement, not in the cable itself.
So the question is, where do you place the splitter vs where do you place the
switch and SFPs. Personally, I would do it Sterling style on new greenfield.
The ONLY reason I do it with the expensive PON is we are a regulated common
carrier with provider of last resort obligations. I have to give POTS that is
battery backed up, legally required to do this.
Cannot risk a 911 call not going through due to a power outage etc. Cannot
trust the customer to not unplug a UPS.

Yeah, so PON vs AE was actually the next research project for me to
tackle.
It seems like there ought to be savings with PON because of lower fiber
count.....lower fiber count ought to lead to smaller/cheaper enclosures.
Less junk at the head end too. I haven't gotten that far yet, but I
was thinking I might "scrimp" with PON. You're saying maybe not?

I would be worried that it will go the way of some of their other ideas.
Cheap... you get what you pay for.
FTTH, I would rather pay more and know it will be solid and be around in the
years to come.
Not an area where you want to scrimp. If you want to scrimp go active ethernet.

Well....I have to build with what's available today. If I delay to wait
for the next hot product, I'll always be waiting.
Besides, I honestly don't know what Ubiquiti brings to the table that
other vendors don't. I suppose it will be cost competitive, but that's
less important to me than having it just work.

I asked the Alphion sales rep about this. He says the optics are coded, yes.
As far as mixing ONT from one vendor with an OLT from another he said in
essence GPON is a standard, but it isn't usually tested across vendors so
whether it works fine, works with bugs, or doesn't work at all is going to be a
matter of chance.

No, generally speaking there is no crossvendor compatibility with GPON.
