What is the frequency bandwidth of Cat6 cable?

• A. 100 MHz
• B. 250 MHz
• C. 500 MHz
• D. 16 MHz

Answer: (B)

Bandwidth in cabling is the highest frequency at which the cable can carry a signal with acceptable quality. For Cat6, that upper limit is 250 MHz. This higher bandwidth compared with Cat5e’s 100 MHz lets the cable support faster data rates over the same copper pairs while maintaining signal integrity, thanks to tighter twists and better separation that reduce crosstalk and keep impedance under control at higher frequencies. That’s why Cat6 can handle modern gigabit and multi-gigabit applications on typical Ethernet distances. The other numbers correspond to different cable grades: 100 MHz is associated with Cat5e, 500 MHz with Cat6a, and 16 MHz is far below what Ethernet standards require.
