I had heard of CAT-6e but my BlackBox catalogue doesn't mention it. BTW 
all the Ms above are MHz.

The BlackBox catalogue does mention CAT-6a and CAT-7 as proposed 
standards. These standards define the electrical perfomance of these 
cables. CAT-6a introduces a new measurement to the standard called Alien 
Cross-Talk.
