Tripp Lite - 25' RJ-45 Molded Shielded CAT-6 Patch Cable - Gray

Yes, this cable is shielded.

Yes, it works great on our Xbox one.

It's a shame the company didn't answer you. Unfortunately, I can't figure out any in-wall installation info. On the manufacturer's website, it says this cable is TIA/EIA and UL Certified (which, as per UL's website, is the equivalent of both "Listed" and "Classified" as of 2013). And both on the website and in supplied info above, unfortunately it's stranded copper rather than solid. Better than CCA but not the best out there. Too bad, cuz otherwise these seem like they'd be perfect for my own purposes.

Yes! Cat6 connections can transfer at rates up to 10gbps@250MHz as long as the transfer is witching reasonable range, if this is a connection for your home network you should be just fine. It’s a shame that they can answer a question about their Xbox working with the cable but can’t answer you on it’s functional speed. Some companies truly don’t care about their customers.
