Fletcher: Many rural LECs are homerunning their fiber back to the CO, such that the optical splitters are only in the CO. It gives them one management point, the highest possible efficiency (you can maximize any every splitter and therefore PON) and a pathway to ActiveE.

If you have an MMR where all of the customers come together, then you can cross-connect all of $PROVIDER_1's customers to a splitter provided by $PROVIDER_1 and cross connect all of $PROVIDER_2's customers to a splitter provided by $PROVIDER_2, etc.
If the splitter is out in the neighborhood, then $PROVIDER_1 and $PROVIDER_2 and... all need to build out to every neighborhood.
If you have the splitter next to the PON gear instead of next to the subscribers, then you remove the relevance of the inability to connect a splitter to multiple OLTs. The splitter becomes the provider interface to the open fiber plant
Owen; Interesting. Do you then lose the cost advantage because you need home run fiber back to the MMR? Do you have examples of plants built with this architecture (I know of one such plant, but I am hoping you will turn up more examples.) regards, Fletcher -- Fletcher Kittredge GWI 8 Pomerleau Street Biddeford, ME 04005-9457 207-602-1134
