So I was just thinking,That is very strange it seems most the patch cords they sell are awg26 for cat6a. All the bulk cable is awg 23.
Maybe the standard is slightly different for cat6a but so far the documents seem to be behind paywalls. I know cat6a cable many times has shielding which will make the cable thicker so maybe they use the smaller wire to avoid very thick cable. You technically do not have to have the pairs with shields on them to be cat6a.
The things though that makes cat6a work is the 550mhz stuff more than anything else and a lot of the cable you see marked cat6 can run at 550mhz.
I suspect the cable you are looking at will work, I would be much more suspect if you were going the full 100 meters. Note normal cat6 cable will go 50 meters at 10gbit. I am not sure if this was added to the standard when they added 2.5 and 5g recommendations. Everyone knows though it works fine to 50 meters and likely more.....it just has not been a official standard.
This all comes down to what actually works and what meets the standard. This is how all those companies get away with selling that flat cable. It works fine for short distance that most home users are using. If it didn't actually work they would get so many bad reviews they couldn't sell it. Few people have the almost $1000 meters that it takes to certify cables.
On the NetGear Orbi router (the one with the 10g port) I wanted to do a wired back haul. After looking again it only has
1x 10G port
1x 2.5G port
3x 1G ports
I will already be filling the 10G port via a cable from my switch&modem. So if I planned to do a wired back haul I would be limited to 2.5G Ethernet which is not ideal since I want to utilize my entire 5GbE. If you read up on this specific router it’s “claim to fame” is that it’s the worlds first quad band router (6Ghz, 2x 5Ghz, 2.4Ghz) utilizing a second 5Ghz band strictly for backhaul between router & satellites. Do you think I’d get more data throughput via the wired backhaul utilizing the 2.5G port? Or using the 5Ghz band? The distance, in my case, from router to satellite is well under 50ft.
