[geeks] Cat6 between buildings and grime proofing?

[Dan Sikorski]

I've been down this road before with wireless, copper, and fiber and I would
definitely put some fiber in.  Sure, it may cost you slightly more to have it
put in, but you'll be in much better shape both from a reliability standpoint
(no possible induction in the line or grounding issues frying hardware at
either end like cat6, no concern with interference or lightning striking
outdoor antennas like wireless) and you've got a better shot of being
future-proofed with fiber than cat6.  The cost difference should be negligable
in the scope of the building project.  Or, while you're burying or running
aerial wire, why not do both cat6 and multiple strands of fiber?  The copper
may come in handy for phones or something else down the line as well.
