   Reminder: when running network cables throughout your house, you'd want CAT6a. Or use fiber (if you know what you are doing or are contracting an installer).

   CAT6a is rated for 10Gbit/s up to 100 meters (328 feet for our weird American friends). Anything lower (6, 5e, 5) is subpar. Anything higher is very specific.

   The CAT7 standard has tera connectors, rather than RJ45. CAT8 is for shorter runs, and designated for datacenters - whom rather use fiber.

   CAT7 with RJ45 is off-standard and you are being lied to. A higher number isn't necessarily better.

     @h3artbl33d @nappex I’d put OM3/4 MM in the walls or traces to pull later, even if it isn’t needed now, it is ready when you need to go faster. Copper is cooked beyond 10Gb and is on its last legs, plus the power consumption is getting really bad. Optics are cheap.
     
     I was working at Krone back in 94 when our keystones were certified Cat5 and good for 100Mb. That was 30 years ago and that speed isn’t up to snuff these days, installations only fell out of warranty 5 years ago.
     
     So while it might sound bonkers to even consider dragging fibre through now but you will be hitting those speeds cheaply within your lifetime.

     @nappex

     If you are putting in the work for the next decade(s), I'd recommend going with CAT6a. Right now, 10Gbit might seems like overkill - but you don't want to redo everything in a couple of years because you saved ten bucks.

     Most datacenters use fiber - as ethernet is not sustainable.

     Just my two cents - you are ofcourse free to do as you please.

     @h3artbl33d for example
     this page https://reolink.com/blog/cat-6-vs-cat-6a/
     describes that 6 is enough for homes and 6a is for datacenters and it is from 2024

     @karinjiri They need to start putting the heatsinks on those like they do on the new SFPs that have a whole Linux OS on them

     I had to deal with this myself fairly recently. I had intended to use 6a everywhere until I encountered the power/heat that it took to run each link at 10Gb. Damn, that stuff gets hot! I came to the realization that 2.5Gb was probably going to be the practical limit. Handling the heat for running 10Gb copper makes the case for optics even more compelling.
     
     Our Cat-6a plan went out the window in favor of OM3.
     
     Protip: I "knew" that optics were hard, expensive, and were a nightmare to work with. I was very, very wrong. OM3/multimode is relatively cheap and far more tolerant than I expected. SFP+ DAC cables also have compelling use cases.

     I've come across those mostly in fibre-to-the-home environments. People replace their troublesome ISP-supplied gateway boxes with an SFP+ device with integrated GPON/XGS-PON/whatever directly in the one device. That goes into the gateway/router/whatever. That's a whole different can of worms though. A very special can of worms.
     
     It's not something I have the pleasure of considering in a docsis 3.1 area. Two blocks away: yes, but here: no.

     @karinjiri yep that's what mine is, I bypass ATT's gear by cloning their MAC, serial number, and model string
     
     It's so much nicer than using their gear...
