$700 seems to be Zayo's floor.

We run 40gbps 10km optics.

I have been quoted prices over $100/mo per strand-mile and as low as $15/mo/strand-mile. A lot of the value seems to be what they suspect you're going to try to do with the strands. 50 Miles to a datacenter, you're gonna be running NxDWDM 100gig waves, big money. Shorter local/metro distance that maybe gets you between your NOC and a small/WISP style tower, or maybe grabbing a piece of an "island" run that can't even connect to anything else, much more reasonable prices.
