If I were you, I would take a serious look at GPON shelves like ZTE and
Calix. CSFP modules let you put two BiDi AE customers on a single slot.
24 port line-card = 48 AE customers. Then I think you can do 8 or 16
port PON cards, 1:32 split = 256 or 512 customers on a single 3U? 4U?
chassis, + the 48 AE customers. This is probably what we're going to end
up doing with the AE deployment we're managing now. The AE is extremely
underutilized and it should've been GPON from the get-go.
If you're doing BiDi now and all the customers home-run to your cabinet,
put the GPON splitters at the cabinet. Cake walk. Same boat we're in.
Except some retrofit because they used a PAIR per customer. And
Clearfield built everything duplex LC. So one strand won't get used in
the field. Big whoop. Call the unused one a backup. I love it when
nobody listens to me. Coulda started BiDi and went right to GPON with
minimal changes.

Ok, so that is the share ratio then.
If I put on 18 customers on a port they would all share the 2.5 down
by 1.25 up.
Or if I use 8 instead 4 of the UBNT Fiber OLT I can get 9 customers on
that ratio.
That would be 8 U plus 4 U space, which I think is probably my max
amount of rack space in the cabinets I am using right now.
That is likely a lot less power than the 12U of 48 port switches I can
use right now, but the share ratio is obviously much worse in the long
run.
Maybe I do a Hybrid and put 4 of the OLT, and still have 4x48 ports
active…
Then in the future if I run into clients complaining about their 1Gbps
rate plan not being fast enough on the share ratio of 1 to 18, I can
move them back to 1 to 1 active.

*Subject: *[AFMUG] UBNT OLT Transition from Active Ethernet to GPON
Anyone tried their PON OLT CPE and OLT 8 port (128 clients per port)
1U unit?
I see pricing around $70 retail for OLT, but haven't seen pricing yet
for the OLT 1U unit.
Also, I'm active fiber right now, so I have full 1 to 1 panels in the
rack already.
If I wanted to 'migrate' to OLT from active I would need some sort of
transition panel/setup right?
Right now my density is 48 ports per 1U 1 to 1 single family home
connections.
The UBNT Fiber OLT has 8 ports handling up to 128 clients each, with
20Gbps uplink capability (not quite sure on those split details yet).
I currently only take a max of 576 per cabinet on active, so I could
easily use just one of these UBNT fiber OLT units.
If I don't care about the share ratio I guess, I would just get
another 576 panel count that spliced 72 count to each port and I'm done.
I'm unclear what that panel/splice would look like though since I've
never actually done GPON.
And I would probably want to not load up that many per port, and
instead maybe get four of the UBNT Fiber OLT units.
That would take up 4U of rack space, the fanout would probably still
take up 4U of rack space, for a total of 8 U.
And I would have instead an 18 customer to 1 port on the GPON instead
of 72 which I like better for future use.
Do these UFiber OLT 1U rackmount units share just 1Gbps per each of
the 8 ports? That would only be 8Gbps needed total.
So I assume the GPON spec they are using can transmit more than that
per each of the 8 GPON ports, right?
