I'm not sure what there is in there. Heard vague recollection of a
pair of CAT5s in there, but not with any certainty. This is why we
need to go survey the place. I would expect their grounds to be
tied given the power system changes, and the conduit to be bonded.
Worst case though we can omit the shield as CAT5 Ethernet is only
magnetically coupled (has isolation transformers) and uses
differential signaling.<br>
<br>
I'm kind of hesitant to introduce fiber to HamWAN where it's not
absolutely necessary. We have enough problems with proper RJ45
terminations, never mind asking people to re-terminate fiber if
something breaks.<br>

<div>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.<br>

<div>Does the conduit already carry a conductor? I would avoid
installing anything but fiber between buildings to simplify
grounding/isolation.</div>
