Cat5 (5e, 6, & 6a) patch cable length

[88keys]

So I understand that the minimum length for these cables is 1 meter.

My question is does it always have to meet that spec to function at 100%?

Is it ok for patch cables from Modem to Router or Router to Switch to be less than 1 meter?

Also, if the Ethernet Cable inside the walls is well over 1 meter, does it make a difference if the cable plugged in to the jack to your NAS or other network device is less than 1 meter?

I could be wrong, but my guess is that none of this matters for home use, but I'm extremely anal when it comes to these things so I must know so I can bring my home network up to code.

1 meter thing is active device to active device. Some devices don't care, others start having problems because the signal is "to loud." Patch panels / wall jacks etc are passive devices.

I have pile of 1/3 meter cables going switch to patch panel.

So basically is okay to have short cables from the wall jack to the device providing the entire connection is greater than 3 meters when interior wall cabling is included
Or in other words, youre good as long as patch cable + interior wall cable is greater than one meter.

Interesting, I never realized there was a minimum length. I have a CAT6 cable less than 1 meter (1 ft) connecting my modem to my router and no problems.

It CAN work, it's just not within the spec required to be guaranteed to work properly.

It also will work with 6" cables - at least mine does. I would never do that in a production environment though, your NEXT (near-end crosstalk) would probably be outrageous. I'm currently not seeing any issues on my managed switch on my home network with such a short cable but it's definitely outside of spec - not enough twists.
