This is true for many utilities. We've been putting this type od fiber

I'm told that utilities are routinely pulling in topside protective
ground wires which have a fiber core. Someone in that industry might
comment. If true, they have the long-haul infrastructure...or will...
to make something like this play.
Agreed, and even longer for some utilities. I recall starting this in about
1986-87, nine yrs before I retired from Detroit Edison Co. 13.2kv
Y-distribution and 40kv subtransmission (then) mostly. There was idle talk
about it on
120kv, 230kv transmission but it sure wasnt done when I was there.
