Kenny, a great question that I forgot to make clear.
There is already conduit between all the buildings. I
confirmed tonight that it's got sufficient capacity to run
an extra CAT5. I think we only have to fish a ~150ft run
between the middle building and the bunker, as there are
spare CAT5s in the conduit between the middle building and
north building, so that should just be plug-n-play. The
trenching to the bunker was done earlier this year as a
response to the awful power outages we suffered this
winter. The north building is now tied into generator
control (and possibly power?) of the bunker.
Does the conduit already carry a conductor? I would avoid
installing anything but fiber between buildings to simplify
grounding/isolation.
