Cat 6, 6a, 7, 7a speeds and distances

[dkljajic]

Hello,

I am working on (updating) a document about twisted pair categories. I cannot find any reliable sources about the speeds and distances that Cat 6, 6a, 7, 7a are capable of. Does anybody know any paper/document on this topic (if it is from Cisco that would be great)?

Thanks

Wikipedia has good details on these

Thank you both for your answers.

I was googling for few hours before posting a question here and encountered the mentioned sites.

I have no doubt about the speeds of Cat 6 and 6a. Since Cat 7 and 7a are not so frequent the documentation is rare.

Hi,

In addition to rare documentations, it is also worth noting that cat 7/a are not even available for purchase at this time.
