Yeah. I really think it's the better way to go for transitioning the
majority of the customers to GPON. Power, rack space, etc. I think the
ZTE lets you do 16 PON and 24 CSFP. I honestly haven't look at GPON
stuff much in the last couple months due to too much shit to do.
Probably gonna go that path this fall. We'll most likely end up leaving
the business customers on BiDi AE, and as long as we're sticking in a
GPON shelf, it makes sense to put everything on a common platform.

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?
