Standard 2.5G down, 1.25G up G-PON port for the uplink, and GigE copper Ethernet ports
for the UNI, which should be able to run fully symmetric. Split ratio I believe starts
at 32:1, with the ability to do a PON-split into two 16:1 sections or further in the
unlikely event that so many 100/40 or higher services are hanging off the same
splitter that contention becomes even remotely likely.
