The main reason we were initially drawn to ubnt was the outdoor POE powered ONU. This would let us re-use a lot of wireless installs with cat5 runs, and it is also how we had previously been doing our activeE FTTH, with a media converter in the NID. Ubnt initially released a spec saying the Nano would be rated for -40C. After resting they revised this to -10C... this told me they didn't design properly and were just hoping it would work using commercial rated parts, like most of their radios do. Not confidence building.
So, if the ONU has to be indoor anyway, the comporable ZTE ONU is less than half the cost of the ubnt. The OLT is also much cheaper if you fully load the OLT. The ZTE is also a mature product with features like VOIP in the ONUs, Multicast IPTV support was another big one for us. Also struggled with getting the UNMS installed and working properly, and ubnt has a horrible track record for maintaining their management tools so it was worrysome to rely on a beta version of their new management platform.
