The bandwidth limit for Category 7a UTP cables is up to 1000 MHz.

The bandwidth limit for Category 7a UTP cables is up to 1000 MHz.

• A. 100 MHz
• B. 200 MHz
• C. 1000 MHz
• D. 1500 MHz

Answer: (C)

The bandwidth limit reflects the highest frequency the cable is specified to carry with acceptable performance. Category 7a is designed to operate up to 1000 MHz, which enables higher data rates over the same copper pair when using proper encoding and signaling. This is why 1000 MHz is the correct rating for Cat7a. The smaller numbers come from older, lower-grade cables, and 1500 MHz would exceed Cat7a’s standard specification, aligning more with higher-performance or differently rated cabling.
