Cable Matters (5-Pack) RJ45 Cat 8 / Cat8 Shielded Metal RJ45 Keystone Jack

Q: Is there a specific Cat8 wall plate manufactured for these? I am specifically looking for a wider plate with one port. Thank you

The plates and panels are rated for up to cat-7. With the cat-8 jacks, you just have to work them in.

Q: Will these fit side by side horizontally and vertically in a Cable Matters wall plates such as the 6 position 180085x10 or 3 position 180083x10?

I'm using them in 2 position plates at the moment, but when I checked against my 6 position plates it looks like it should work.

Q: If i run a cat 8 eth. cable do i need a cat8 plug or can i just use a rj45 connection?

Cat 8 refers to the data transmission quality of the cable and its male ends(plugs) and the quality of the female jack. I am not aware of any Ethernet connection type besides RJ-45 for Cat 8. As along as cable and jack are listed/rated as Cat 8 you will get optimum data transmission (i.e. speed). Any Ethernet cable and mating jacks that are RJ-45 configured will be mechanically compatible. For example, mixing Cat 5 with Cat 8 may lower the maximum data transmission speed below Cat 8.

Q: Are these compatible with cat 7a 23awg cable without the loss of mhz?

It's rated for Cat which is 1000mhz , I'm not exactly sure on how to test frequency of copper . I'd say do your research . There are a few sites to look at . One of which i recommend is FS.com I got my Cat8 Stranded Patch Cable there to use with my Cat7a Soild Cable .
