RE: Last Mile Design

In New Zealand we have a mostly (any town of about 20k population or more) nationwide FTTH rollout underway 
(government/private partnership) that is mostly based on GPON. Both Point to Point and Dark Fibre are available as 
well. The service is layer 2 QinQ delivered to the retail service providers, (1/16 split on the GPON) while the fibre 
infrastructure provider is barred from retail service sales. GPON speeds generally delivered are 100/50, 200/200 and 
1G/500. In general the real world result of this is a network that performs fantastically for both retail and SMB. 
Larger businesses are often delivered over single strand dark Fibre, but in practice the 1G/500M service works 
extremely well for most situations. 10G over the PON network is about to start a trial phase, but the ready 
availability of DF significantly reduces the urgency of this (8x10G over cheap CWDM fibre mux's makes for a nice 
solution).
