The $60 will do what he told you, and it is a very good deal...But it isn’t on a completely fiber (ethernet) system unless you live in Knoxville or Houston.
The cable and telcos all have legacy coax and twisted pair technology mixed in with fiber in their networks, which greatly reduces the speed and reliability in relation to an all fiber network. One test for determining whether someone is offering you an all fiber network is if the upload and download speeds are the same.
Speed on an ethernet system is also blazing fast - you can get up to 1 gig in Knoxville and up to 10 gigs in Houston.
It's part of a rather stupendous system installed in this area.
We even have manhole covers that are WELDED, and when opened, there are armed fire teams surrounding the area.
I don't think most of this is hooked up to civilian concoctions.
