Have you accounted for glass as opposed to vacuum? And the fact that fiber optic networks can't be straight lines if 
their purpose is to aggregate traffic along the way and they also need to follow some less-than-straight right of way.

Howdy,

Why is latency between the east and west coasts so bad? Speed of light
accounts for about 15ms each direction for a 30ms round trip. Where does
the other 30ms come from and why haven't we gotten rid of it?

Wallstreet did :)

So THAT'S why CERN wants to build an even bigger accelerator than the LHC!
