The 2.4Ghz download datarate is delivered to EVERY customer in a G-Pon system (I'm alas, on an older BPON FiOS system). Every house sees the full datarate, and only the data addressed for that customer is "picked off" and delivered to the customer-side interface.

If the system designer decided to be more DSL-like and overbook shared bandwidth, every customer could be assigned a 1-Gbps download rate that each user could "peak" at (well, two could do the full rate at once). The boxes would have to have gigabit ethernet ports rather than 100Mhz ones (like mine has anyway), but that'd be a relatively minor hardware change to the boxes.

I wonder if this is what Google has in mind. Bandwidth is going to be shared pretty strongly at the next junction upstream anyway. A neighborhood of only a thousand houses isn't going to be given a Terabit feed.

btw - At least with Verizon, I understand that in practice they split the GPON more like 32 ways and BPON more like 16 ways, even if they can do more in theory. Just stuff I've read in forums (I having FiOS), I don't know for sure.
