If it's done on a box owned by the incumbent then sharing has evolved into giving away free service to competitors. It's different when copper pairs into a house could be latched onto anyone's switch. Once you start requiring a carrier to give away capacity in it's network that's different. Also, diversity/redundancy becomes dodgy at this point. Not that the billions of dollars they are making didn't come into the discussion, but it seems like its more complicated to share fiber access than it was to share copper pairs. 2012/3/22 John Kreno <john.kreno@gmail.com>
This sharing can be done at a layer-3 or as you say at the time slot level or lambda level. It's no different than what is happening with the copper already. It's not like they have to give it away for free. They just have to offer it to other carriers at cost. This will hopefully provide more of a competitive market. But I don't see Verizon giving into it, nor Comcast or any other provider that has fiber. Verizon campaigned hard to have fiber removed from the equal access legalize so like most of these other large companies, they don't want to share their new toy with the other children.

which I don't see happening unless its by force via government. At the end of the day there needs to be the ability to allow competitors in so of course they shouldnt be allowed to rip out the regulated part and replace it with a unregulated one.
Maybe I'm missing something, but how exactly does one share fiber? Isn't it usually a closed loop between DWDM or Sonet nodes? It doesn't seem fair to force the incumbents to start handing out lambdas and timeslots to their competitors on the business side. I guess passive optical can be shared depending on the details of the network, but that would still be much different than sharing copper pairs.
