@ Kitz,
Thanks greatly for a much better comment upon my "more expensive" solution.
I had also omitted the lower order local fibre distribution where the big fibre bundles are subdivided in a distribution node (= a fat joint).
At this point the technology changes (slightly) and several small diameter quite different pipes this time usually already containing four tubes fan out to the local FTTCs.
Quite often only one tube in a pipe has a small fibre bundle blown through it at present.
Within the FTTC four individual tiny fibre pipes feed the fibre from a white termination box to the DSLAM plugs.
Clearly this technology will have to change if "Fibre on demand" becomes a common reality.
Perhaps this is the reason for the seemingly extortionate cost of installing the "On demand" FTTP.
{ I have lots of photographs but cannot load them on this site due to the reasonably small (but very necessary) file size limitation}
For an innovative ground-breaking solution designed specifically from day one to provide true FTTP to every house, over vast mainly rural areas, have a look at the splendid efforts up at B4RN.
