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...
