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.
You agree on a price per distance (e.g.: mile/foot/whatnot).
Lets say the cable costs $25k to install for the distance of 5000 feet.
That cable has 144 strands.
You need access to one strand. If you install it yourself, it will cost you $25k. If you share the pro-rata cost, it comes out around $174 for that strand. Lets say they mark it up 10x (profit, unused strands), would you pay $1740 for access? What does emergency restoration cost?
WDM/DWDM add cost to that strand, but also increase the capacity based on what your overall lit capacity may be on a route. There are various cwdm/dwdm systems that range the usual 10/20/40/80/100km ranges. You obviously need to do the math yourselves on this. You may find the ROI is better than you think...
