One of my big struggles now is how long to make the "local loop" element of the network. I know that "local loop" typically refers to a copper twisted pair but I'm not sure exactly what you would call its replacement in FTTH-speak.
Initially I had imagined putting a concentration point in the middle of our residence (100 meters away) where I could install active equipment. Then any operator could come and patch into us to offer services at the edge of our network. However, now I'm beginning to wonder if I should plan on taking all fibers all the way back down to the exchange 600 meters away.
If I thought that I would surely stop at just laying fiber in our residence then locating the active equipment next to us would probably be a good idea. However, the situation becomes a bit more complicated if I ever decide to spread out the fixed costs of connecting to exchange by expanding the project to other subdivisions at a later date.
I'm not sure that it makes good economic sense to place active equipment in each subdivision of a small village. It's not cost effective for the equipment and it surely introduces more potential points of failure. At the same time, it may not be cost effective to run a large amount of fiber to the edges of the village several kilometers away either.
Right now this is playing out in Paris. France Telecom's PON network requires less physical space than Iliad/Free's point-to-point network. That means that Free is likely looking for property all over Paris where it can locate active equipment to terminate its fiber closer to users.
I don't need to make all these decisions now since I can wait to see how the project progresses and if other subdivisions are interested in connecting with us. One of the important decisions for now though is how big of conduit I should put in leaving our residence out to the exchange? Do I plan for something big enough to accommodate future growth - even if it will increase my up-front fixed costs?
