content: Networking gurus here, I need some help finding a proper cable for my home media streaming and desktop sharing setup.The hardware is simple and straightforward: 'A' side is a Mac Mini w/ NBASE-T NIC, and 'B' side is a Thunderbolt 3 NBASE-T NIC. Both NICs are based on Aquantia AQC-107 10GbE SoC.Now the critical part: the interconnection.I prefer a flat cable as I can just hide it under the carpet, running from my lab to my bedroom, which is ~12m apart including routing length. Thus, I need a 50ft cable.Theoretically, for under 55m, I should be able to get around with a CAT 6 cable, but I don't know if I will have speed loss.I tested with a random CAT 6 flat cable at 15ft, and it achieved 9.4Gbps using iperf TCP mode, 10 threads, which is pretty cool.But for triple the distance, I have no idea what would happen.Ideally a CAT 6A or higher is better, but it seems like no one is selling true flat CAT 6A+ on Amazon.So the question: does such flat CAT 6A+ exist? I don't really expect CAT 7, as with RJ45 it won't make any difference. CAT 6A would be totally fine, and if someone tested a CAT 6 can also do 10G at 50ft, I would gladly take that as well.PS: I know Buffalo has true CAT 6A flat cables, but it's only available in Asia. I'm currently in US, and I need it NOW.//Edit: title changed from flex to flat. Brain farted.

content: Is the carpet properly laid and stretched onto smoothedge, that spiky stuff around the edges ?If so you can run your cable just inside the smoothedge and against the underlay and slot the smoothedge wherever you need to pop it out.At a pinch you could also place cable between smoothedge and the wall where the smoothedge has an undercut edge and tuck the carpet back down over it then maybe not needing to re-stretch the carpet onto the smoothedge.Then you can use your preferred cable instead of a flat one.

content: CAT5e should be also fine for that length.

content: Solid core CAT5e works for 10GBase-T up to about 45m. Patch cables with stranded wires need to be derated. Just saying.Personally I'd go for 10GBase-SR (multimode fiber).

content: Quote from: blueskull on March 09, 2019, 07:22:59 pmOver those sorts of distances even fairly average cable will get you 10Gbps.We run regular Cat 6 at work over about 30-40 metres and have no issues at those speeds.

content: Flat CAT6A double insulated cable does exist. However, it is usually thicker than the flat CAT5E cable, and hard to find one from reputable brands.Without proper test equipment (Fluke DSX / Agilent Wirescope / etc), I would not suggest purchasing any flat CAT6A cable since a lot of them cannot pass the compliant test.

content: As CAT7 they can be find here:https://www.aliexpress.com/item/32815993041.htmlthey are thick but never cuted one to verify if is trueAs for flat cable i think they not exists since it's more hard to put the outter foilCAT8 is already poping out too

content: I did test a few 10+ meters SAMZHE cables in the past. Their CAT5E cable (SAMZHE FTP-305) cannot past CAT5E compliance test. Their CAT6A cable passes CAT5E test, but not CAT6A.
