There is no reason fiber is more expensive than copper, which means SS is cheap, as cheap as copper.
Copper isn't cheap, its just there already.
Unbundled copper costs about $10/M or so, which means SS fiber can't be more expensive.
What is SS?
Single star.
No, most of the cost isn't in running the cabling. Today most of the cost is in lighting the fiber, though that varies on where you're running the cabling and what gear you're using to light it.
On page 11 of google slide, http://static.googleusercontent.com/external_content/untrusted_dlcp/research... it is stated that "Trenching consists of 70-80% of the total cost for infrastructure build".
PON is preferred by carriers because it works in their existing equipment
Their existing equipment was SS copper and MDF.
Planning for a carrier network is very different (different requirements) than for a greenfield muni system.
Surely, transition from copper to fiber is not trivial, but it helps a lot that fiber cables are thinner than copper cables. Masataka Ohta
