The 18" or so is a "standard". We've gone by lights in 70-80ft runs
without problems. Just try to not run parallel to power lines, etc. The
twisted pairs are really quite immune to most interference if you do that
as below.

Just replace the ends and do it right. You must use "pairs" to that you
have immunity from interference. (1 and 2 is one pair, 3 and 6 is the
other)

You can let me know. I've setup several schools without any commercial
stuff (other than on the workstation.)  They've been running for years
with very little to do, management wise, other than users and shares.
