[K12OSN] OT building to building ethernet wiring

[dale]

Hello,
	I wanted to get a wiring opinion from the list.  I need to extend a 
network from a school office to a few adjacent buildings.  Each building 
will have 5 or less workstations or LTS clients.  The lengths are less 
than 30m.  I am considering running cat5e/6 thru metal conduit -vs- 
fiber.  I am concerned with ground potential between buildings and cable 
loss etc -vs- cat2fiber and fiber2cat costs.  Can I try it with cat, or 
should I just use fiber?

Thanks,

Dale
