For those of you who have dark fiber access, what kind of costs do you have?
I'm thinking more of the cost to access these strands? IRU costs, lease, swaps with other providers, etc? I want some sort of ballpark costs to know what's reasonable when we start looking at this over wavelengths for shorter paths.
