For *tomorrows* FTTP systems, there is labwork being done on WDM-PON -
where the fibre is still split 32 ways up to 64 ways in the middle of
the physical cable network, however in some implementations every
endpoint gets a dedicated wavelength, with the 32 or 64 wavelengths
being sent from the head-end.
This effectively takes out all the sharing aspects - every customer gets
a dedicated gigabit or even 10Gig optical path direct from the head-end
to their premise! (drool).
Now try to imagine the backhaul required to service the head-end if
5000-10000 users are hanging off the head-end with 10Gig dedicated links
