Which category cable has a bandwidth of 250 MHz?

• A. Cat5e
• B. Cat6
• C. Cat6A
• D. Cat3

Answer: (B)

Bandwidth stated for Ethernet cables is the highest frequency the cable can carry with acceptable signal quality. A cable rated at 250 MHz is designed for higher-frequency signals than the others, thanks to tighter twists and better isolation that reduce crosstalk and support higher data rates. This makes it suitable for faster network standards over practical distances. The other options have different MHz ratings—100 MHz, 500 MHz, and 16 MHz—so they don’t match the 250 MHz specification. Therefore, the category with 250 MHz is the one that enables higher-speed networks, Category 6.
