I have seen several references to that, but none of them were "official" in any
capacity. I also see lots of places selling 6" and 12" patch cables. I would
certainly think that they would have problems if they didn't meet spec.
That said, I've worked in environments in the past were cable lengths were an
issue because designers had minimum distances they had to overcome and as such
they didn't take into account that signal propagation would ever exceed the
speed of light. When physical configurations changed and there was now 18"
between units instead of 18', things started failing. Fortunately they were
easily fixed, but at one point during the process the requirement was changed
to ship a 50' cable with that unit in question because anything shorter failed.

I have never seen an ANSI/TIA/EIA spec that dictates cable length minimums.
Only that there must not be more than .5" untwisted at either end.

I'm getting ready to replace some switch stacks. Our current cabling(patch to
switch) is a mess, so I'm ripping out and starting from scratch.
I'm looking around at cable design, and I like the short 6'' cat5 cables, like
this:

My concern is I think the IEEE minimum CAT5 cable length is 1.5 meters, but I'm
not sure if that's only for cables between active devices or not.
Anyone know for sure and/or have experience using short cables between patch
and switch? Any issues?
Not sure if it matters, but it's gig to the desktop POE.
Thanks,
