Regarding the distance, our ZTE will support up to 60 km, but max difference of 20km between ONU on one PON. There's just a range parameter that needs to be set.
We ordered C+ optics and see a real optical budget of 33dB. The OLT is about +5.5 tx and -34 min rx sensitivity. The ONU about + 0.5 tx and -28 rx sens. I've been very impressed with the optical performance. We did test the ubnt as well.
