Flat ethernet vs. round ethernet cabling in the wiring closet

Hello all,

I tried to post this question before and it never posted.

I have several clients that their wiring closets are a mess.  We are using standard round ethernet cabling.  I have read much about flat ethernet cabling but I cannot get an answer for one question which is:  If we use standard cabling to go from the data drop in the wall back to the data drop in the patch panel in the wiring closet, can we use flat ethernet cabling for the patch cables (3 foot, 7 foot, and 15 foot cables) that go from the data drop in the patch panel to the switches in the patch panel?

I know that we do not want to do this with PoE devices, but what about computers and printers?  Can this be done without any crosstalk and EMI interference?

Thanks,

Kelly W.

"Can this be done without any crosstalk and EMI interference?"
The "twisted" in "twisted pair" is what is supposed to stop crosstalk and EMI.  If your cable is up to spec (CAT5, CAT6, etc.) it doesn't matter what shape the cable takes.  In other words, you should be able to use flat or round cable wherever you like as long as it's well-made.

5m and less use ultra-slim CAT6 cable that is capable of 10GbE.


It's much easier to work with and tie up. That leads to nice tidy wiring closets.

For longer runs, then standard round CAT6 patch cables. We tie in groups of four top and four bottom then tie those two bundles together for their run.

Fibre is rather easy to work with just watch the round arc.

Thank you all.  Have chosen not to use flat cables at all

This is the best money I have ever spent. I cannot not tell you how many times these folks have saved my bacon. I learn so much from the contributors.
