Question About Flat Ethernet Cable’s?
Sorry but I’m old school and at work we always pulled the round cables when we needed to add to the network (Back then there was no such thing as flat Ethernet cable’s) I am about to hardwire my devices in all my rooms. I am going to pull cat 7 because of the shielding it provides. My question is are there any differences between the older round cables compared to the flat ones? TIA

I don't think there are any major advantages, network folks like them because of cable management in network cabinets. If you are pulling in walls though, I would imagine round cables would be far easier. Why cat 7 though? You could do a shielded cat 6 for far less money and nothing is 10 gig yet.

All cat7 is shielded.
Some cat6 is, too.
I don't think you're going to find Cat7 spec flat cable that you'll be able to run across a house. Patch cables, maybe. But a roll to pull? I would doubt it.
You're probably fine with Cat5e in the walls.
If new construction, cat6 may be fine/Overkill.
Check out the conduit fill guide below as to why: as the category number increases, you're significantly increasing cable diameter which reduces the number of cables per hole in the drop plate that you're going to drill.



What's the purpose of the network you're running?

Nothing major. Just fire tvs and apple tv. Just going to get some devices off the wifi

If that's what I were going for, I would do cat5e


-guy who bought a roll of Cat6a cheaper than he could find cat5e and did about half as many runs as planned because the bulk of the cables were annoying to run through the wall

Twisted round cables will have better noise reduction, longer distance capabilities, etc. if you are operating at the absolute extremes of network capabilities.

For a home user, I don't think you will have any scenarios that would create any measurable differences. Go with whatever is better for your functional situation. If pulling cables, round will be a better choice. If trying to hide cables, flat can be better as they slide under baseboard and things easier.

There is zero need for shielded cabling. None.

As for distance limitations the limitation for each category type is 100 meters (328 feet). Personally I would run CAT6 as it's still at the lower end of the cost spectrum and provides excellent performance. However, if you're insistent on running flat cable it's going to add to the price of the cable.

Just be sure to run parallel to any electrical wires and maintain at least a foot distance from electrical cabling. If you have to cross electrical do it at a 90.

Anything in a home over Cat6 is overkill. Your distances aren't long enough to matter. Also, unless you have an xray machine in your laundry room, shielded cable of any kind is also throwing money away in a residence.
you can't just pull shielded cable either. If each cable is not grounded properly, it will have the opposite effect, it will turn into an antenna.

I’ll second this in terms of residential use in particular.

Good info.

This is where shielding comes into play. Typically, this is easily avoidable in a home. Industrial applications, particularly in Motor Control Centers, are where shielding is typically used and in many cases a must. If you use shielding without proper grounding, it is, if not useless, at least relatively ineffective anyway.
