Exellent paper on FTTH architectures

[Here is an excellent paper on the pros and cons of various FTTh architectures. I fully agree with authors that home run fiber with Ethernet is the optimal solution. Not only does home run fiber provide unlimited bandwidth and greater flexibility - it also enables innovative business models such as customer owned fiber and layer 1 peer to peer interconnects between subscribers. The only thing missing in this report is FTTh architectures for initial low take up deployments (less than 10%). Virtually all FTTh analysis assumes Greenfield deployments with close to 100% takeup. I think there is some new innovative "slot" and micro-conduit technologies that will substantially reduce costs for deploying FTTH in existing neighbourhoods, even with initial low take-ups-- BSA]
