Ken, yes this is a key benefit of PON over Coax/DSL based service. However you do use up some of your optical budget with distance, which may impact how many subscribers you can serve on that PON. So, you have to decide, is it worth it to feed this PON from a hut 20 miles away, if it means I can only fit 8 or 16 customers per PON? Or should I place an OLT closer and be able to serve 64 per PON. PON ports are expensive, take power to operate, needing to place larger cable and handholes is expensive, and burning up hundreds of strand-miles carrying PONs that can only feed 8 customers is expensive. In our network, we plan to serve about 10 mile radius from a cabinet/hut.
