The original iteration of GPON would let you feed 32 subs at 12.5 miles. And
you still had optical budget, it was a timing limitation. Not sure what the
limit is these days.

Ken, yes this is a key benefit of PON over Coax/DSL based service. However you
do use up some of your optical budget with distance, which may impact how many
subscribers you can serve on that PON. So, you have to decide, is it worth it
to feed this PON from a hut 20 miles away, if it means I can only fit 8 or 16
customers per PON? Or should I place an OLT closer and be able to serve 64 per
PON. PON ports are expensive, take power to operate, needing to place larger
cable and handholes is expensive, and burning up hundreds of strand-miles
carrying PONs that can only feed 8 customers is expensive. In our network, we
plan to serve about 10 mile radius from a cabinet/hut.

Can’t you feed a PON over fiber from 10, 20, 30 miles away if you have the
strands? I used to assume it was like phone pedestals and crossboxes, cable TV
nodes, or UVerse cabinets that had to be within a block or two of the customer.
But it seems like you could find a location for an active electronics hut
miles away along your fiber route.

We have a few cabinet sites like this, using DDB Cabinets. For fiber slack we
just place a handhole next to them. What works best is buying a pre-loaded
fiber panel with a few hundred ft pigtail and then splicing to your OSP cable
in the handhole.
Lessons learned after having cabinets in the field for close to 10 years:
1. They overheat very quickly if the A/C fails. Like 20 minutes.
2. Hard to store enough batteries/UPS for reasonable length of backup to roll
a generator. The cabinet pictured, when fully loaded only had 90 minutes of
battery power, and that doesnt include A/C. We tried burying batteries in a
handhole but they eventually flooded and failed.
3. They are likely to end up being too small, fiber networks tend to grow.
4. You may want to buy property nearby to place a hut later, and nobody will
want to sell
5. It's a lot of work and overnight splicing to re-reoute a few hundred
strands of fiber out of a cabinet and into a hut without causing major outages.
I am only building fiber huts for new sites. More cost but so much easier to
live with.

I'm looking for a small outdoor cabinet may 19" rack about 10U. Would like
something that could work as a Handhole/Cabinet where I can store fiber loop
under it. Never had to shop for anything like this.
