What is the testing frequency of a Category 6/Class E cable?

The main idea here is the bandwidth the cable is tested and guaranteed to support. For Category 6, often called Class E in older documents, the standard specifies testing up to 250 MHz. That higher frequency compared with Category 5e’s 100 MHz reflects stricter performance requirements for crosstalk and return loss to enable higher data rates. Cat6a raises the bar further to 500 MHz, which is why 250 MHz is the appropriate figure for Cat6/Class E. The other options don’t fit because 100 MHz aligns with Cat5e, 350 MHz isn’t a standard category limit, and 500 MHz corresponds to Cat6a.
