What is Cat 6e or Cat 7?

As far as TIA (Telecommunications Industry Association) standards go, Cat 6e and Cat 7 do not exist. Standards for Cat 6e or Cat 7 have not been approved by TIA; therefore, Cat 6 is currently the highest TIA standard for twisted-pair communications cable (As of 3/02/2008).

If you see cable called "Cat 7 or Cat 6e" (or some other higher number), that is just a name that a company made up to put on their cable. One manufacturer's Cat 6e or Cat 7 could be built by totally different standards and specifications than another manufacturer's cable.

So, if you still want to pay the extra bucks to get Cat 6e or Cat 7, just know that you will be getting cable that could be made anyway the manufacturer feels like it. To me, your best bet is to go with Cat 6 cable, this way you can rest easy knowing that your cable is up to standards.

TIA-568B-2.10 Augmented Category 6 (CAT6a)cabling standard was approved on 8-Feb-2008. CAT7, not so much.

CAT7 is probably a decade or more away.

Class F ISO/IEC 11801, 2nd Ed., Information technology – Generic Cabling for Customer Premises, 2002, is the ratified standard for Category 7/ Class F cabling and was ratified when Category 6 and 5e were ratified by ISO back in 2002. Augmented Category 7 (Cat7a) was approved also on 8-Feb-2008 when Cat6a was ratified.

although TIA is not actively developing a standard for category 7 at this time, it
is acceptable to specify class F cabling in North American and other markets. The rationale for this is that, in addition
to being recognized by BICSI, NEMA, IEEE, and other standards organizations, class F is simply a superset
of TIA category 6A requirements. Field test requirements and adapters for class F cabling qualification have
been commercially available since 2002.

There is no TIA or ISO Cat6e category published, the term Cat6e is a vendor term suggested by certain US manufacturers to try and gain an advantage with smoke and mirrors. Or it is Cat6a that has been mis-diagnosed as Cat6e.

Check out or or google Class F and Category 7. There is over a million Cat 7 installed outlets globally and growing.

What is the actual technical difference between cat6e and cat6a

"Cat 6e" is a manufacturer or dealer label for cable that doesn't meet the actual 6a standard.

Cat 6e mostly used in networking cabling.Speed is very good.Cat 7 is not authorized in present time. So Cat 6e is used.

Cat 6e and cat 7 remain non-existant in the standard eyes of the TIA and the IEEE. In short, they are not recognized. TYCO industries takes credit for having a cable soley manufactured for them and promotes it as cat 6e. In fact, their cat's are no more than a Cat 6a that has been force tested slightly beyond the recommended thresholds. Spectrum analysis proved that the so-called cat 6e sustained a 520 MHZ bandwidth with some loss of data. For the record, use fiber optic cable if your needs exceed 500 MHZ.
