Why more headache?
Discussion
The connectors are different, I believe. You might be able to use a cat6/7 cable into the wall plates though. I just recall looking into it a year back and 8 had considerations that 5/6/7(e) did not.
Just checked and they are backwards compatible, but the connector itself is bigger and more expensive too.
They seem the same rj45
Yeah, they are rj45, but they are cat8. They are also getting cheaper now days. I also think that the cat8 do not yet have solid standards, but it may not be a huge deal. The cable itself is pricey compared to 6/6a/7, but it is only a one time thing. I just wonder if fiber might be better, all things considered.
