Basically when the customer (typically the service provider, but not always) orders a loop to a customer the muni provider would OTDR shoot it from the handoff point to the service provider to the prem. They would be responsible for insuring a reasonable performance of the fiber between those two end points.
Been tried multiple times and I've never seen it work in the US, Canada, Europe, or Latin America. That's not to say it can't work, but there lots of reasons why it doesn't and I don't think anyone has suggested anything here that I haven't already seen fail.
So let me be clear, here, because I'm semi-married to this idea... You're asserting that it is not practical to offer L1 optical per-sub handoffs to L2/3 ISPs, because a) the circuits can't be built reliably, b) the circuits won't run reliably over the long run, c) if something *does break*, it's hard or expensive to determine where, or d) each side will say it's the other side's fault, and things won't get fixed? I can't see any difference between building it for their L2 access box and my own. I simply don't believe (b). (c) seems questionable as well, so I assume you have to mean (d).
Dry pairs are impossible to order these days for a reason.
Certainly: because you have to get them from incumbents, who don't want you to use a cheap service to provide yourself something they could charge you a lot more money for. You assert a technical reason? Cheers, -- jra -- Jay R.
