yeah and actually in many larger cities not only that the cables and
some times splice cases are underground with transformers. Those things
never go up in a ball of fire. Oh wait its a high voltage device
surrounded with flammable oil in a confined space with built in
ventilation...

With 100% underground construction, fire doesn't bother it much.
However most folks probably don't realize that handholes will burn.
They are polymer concrete.

If you can gain entry to do that. Look at the major CA fire zones that
just happened: nobody was getting in for weeks on end. But I did see a
lot of emergency PCNs for new microwave paths that skipped over closed
areas. Nobody is going to let you work on a temporary splice next to a
building that's partially collapsed. Or a broken gas line. Or a broken
water line that's undermining the area. Roads/bridges can become
impassable in seconds. So many variables that could keep you out of
any given area you could shoot over with microwave much faster. With
fire tower sites are often defensible structures for fire crews.
In earthquake or fire disaster planning always include microwave. If
you have to realign you're guaranteed to only need access to the
endpoints not potentially X number of midpoints if there's more than
one fiber break.
