Thanks everyone. I think I didn't describe my question well though. :)

What I'm curious about is the minimum safe cable length, not the type of cable.
How short of a cable can I use(assuming I'm using Cat5e or Cat6).
I see 6'' Cat5e/Cat6 cables for sale, but they seem to break the IEEE guidance 
on min length.
I'm not sure though if that guidance on minimum length is only for between 
active devices, or would it also include between switches and patch panels? I'm 
curious if anyone has real world experience using 6'' cabling for patch to 
switch?

What I would like to accomplish is to use 6'' cabling when building my new 
switch stacks, but I don't want weird layer1 headaches.


Thanks,
Jon

Well, not exactly correct on the Cat 5 cabling.

The original specification for gigabit Ethernet over copper, 1000BASE-T or IEEE 
802.3ab, was the minimum of Cat 5 cable or better.

But I agree that it should be Cat 5e or Cat 6. Cat 6 being the preferred choice 
for future growth. But that begs the question as to what are the patch panels 
rated as?

Cat5 isn't good enough for Gb. You need at least Cat5e and preferably Cat6.

I've personally always used Panduit cabling boxes. Whenever I've tried to play 
loose with the Ethernet spec, it's always come back to bite me, eventually.

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,
Jon
