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.

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?
