There is no minimum length for a Cat X cable.
I did some research on this awhile back since I knew that there is a maximum cable length, 100 meters for 100 MBPS and 1 GBPS. If you pass that the timing gets
off so speed drops to 10 MBPS. I know from experience.

I have an old GB NIC desktop computer linked to a GB NAS thru an early GB switch that may have _less_ than 3ft Cat5 jumpers between and it has been running trouble free for years.

hmmm. and a 30' cable? maybe? sorry. i remember the old coax-ethernet days where you had to have a certain length of cable inbetween Tee connectors for the computers. needed the prop delay to detect collisions.
might be 1G needs a bit of a prop delay? i try to avoid the twilight zone, but looks like we're already there.
