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

The correct answer is C. 250 MHz. Category 6 (TIA standard) / Class E (ISO/IEC standard) cables are tested and specified up to 250 MHz. This is a key differentiator across copper cable categories: Cat 5e is tested to 100 MHz, Cat 6/Class E to 250 MHz, Cat 6A/Class EA to 500 MHz, and Cat 7/Class F to 600 MHz…

Explanation

Category 6 (TIA standard) / Class E (ISO/IEC standard) cables are tested and specified up to 250 MHz. This is a key differentiator across copper cable categories: Cat 5e is tested to 100 MHz, Cat 6/Class E to 250 MHz, Cat 6A/Class EA to 500 MHz, and Cat 7/Class F to 600 MHz. The higher the testing frequency, the greater the cable's ability to support high-bandwidth applications. Cat 6 at 250 MHz supports Gigabit Ethernet and is backward-compatible with lower-category applications.
