Lets start taking bets for how long it will last this time.

I'll bet a dollar on 9-12 months... :)

Why 8Gbps? Seems like an odd number when SFP models generally are 10, 25, 40, 100.

80% loading of a link is where queuing theory says latency goes up fast. With 10Gbps links (be they 10Gbps ethernet links or XGSPON), you don't really want to go up above 80% load. 10Gbps PON is becoming mainstream now, while 25Gbps PON is still only in early testing at this point.

I don't understand why one would run PON when you might as well run the fiber all the way directly to the customer without any splitting and only be limited by the SFP modules attached to the end. Unless the last piece is still copper it makes no sense. Wouldn't a splitter also cost more?

I have 4 fiber strands directly run to my municipal power company and so does everyone else in my city. I can do as much speed as a provider is willing to offer which currently is up to 25gbit. [1]
