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.So, you share fiber by having one guy control one wavelength (color, e.g. red) and another guy control another wavelength (e.g. blue). And when you install it to a home or business, the "prism" sits up on the phone pole and just splits out the one wavelength that is intended for that location. You can't even stray out of your color: if you do, the prism will bend the light in a way that misses the target beam.So who get's the keys the the cabinet it resides in? The LEC? All of the CLECs? The FCC? Who's responsible for maintaining the box given it's now shared. Who takes legal responsibility for outages caused by things done to this magical prism you speak of?
A fiber wavelength in the described PON scenario is operationally identical to a dedicated fiber strand or a dedicated copper pair with respect to management and connection. There's a physical "wire" coming out at each end which is connected to equipment with "lights" it. The problem is reduced to the already solved one of how to "share" copper pairs in a single cable.
