Shielding on Ethernet cables protects signals from interference and ensures reliable data transmission.
Shielding on Ethernet cables protects signals from interference and ensures reliable data transmission.
I'm preparing my new home with Cat6A cabling, aiming for full 10GbE performance over more than 150 feet. The challenge is choosing the right shielding—should I opt for a cable that covers everything (like S/UTP or F/UTP) or shield each pair separately (such as U/FTP or U/STP)? I'm searching for a solution that offers both full and half-shielded options, but these specific types are hard to locate. Cat6A UTP cables are common, yet they don't meet my needs. Please let me know if you can assist.
U/FTP offers better protection against EMI from other cables and minimizes crosstalk between pairs inside the cable, whereas F/UTP only shields against external cables and doesn't isolate each pair internally. Keep in mind that F/UTP is simpler to handle because it uses just one layer of foil. U/FTP is more complex due to four layers of foil per cable. It’s rarely necessary for home use, but if required, consider fiber optic solutions. I’d also suggest opting for OM4 fibre since it supports full 10Gb speeds and allows future upgrades to higher bandwidths.
I haven't seen U/STP only for braiding on cables instead of pairs for S/UTP or S/FTP. When comparing S/UTP and F/UTP, I don’t think there’s much distinction in shielding performance. For fiber, the most practical method without costly splicing tools is to connect directly to keystone jacks. You can use wall plates that fit LC to LC (or whatever you need) for easier installation than IDC plates for Cat 6A. However, keep in mind the cables are more fragile, which matters. You can connect LC to LC directly in wall plates without needing termination; just run the cable and attach connectors at each end.
I believe I’ll stick with Cat6A. Does this Ethernet cord look acceptable? It advertises S/FTP, and this appears to be the cheapest I’ve ever seen it. It looks like a solid offer. EDIT: I just noticed the cable is rated for CM instead of CMR or CMP. Still, is it still a good choice?
I discovered the identical cable in the CMR standard again—it looks like a solid deal.
I don’t feel the need to discuss those ratings much. It seems the UK and US might use different standards for cable fire ratings, so I’m not very familiar with US ones. Terms like CM, CMR are from the NEC codes, which aren’t relevant here. Still, both appear to be at least In-wall CM rated. The seller on eBay lists CMR but the images show In-wall CM, which I think is okay.
Thank you for your assistance. The cable I chose is based on the inspector's decision to permit the CMR option over the CMP cable.
