Which bandwidth corresponds to Cat5e?

Which bandwidth corresponds to Cat5e?

• A. 100 MHz
• B. 50 MHz
• C. 200 MHz
• D. 1000 MHz

Answer: (A)

Understanding cable bandwidth ratings for twisted-pair Ethernet: Cat5e is specified to support up to 100 MHz. Bandwidth here means the highest frequency content the cable can carry with acceptable signal integrity, which limits how much data per second the cable can effectively handle. Even though Cat5e can run at gigabit speeds, that performance comes from signaling techniques and using all four pairs, not from a higher frequency rating—the per-pair bandwidth remains 100 MHz. The other frequencies don’t fit Cat5e: 50 MHz is below the spec, 200 MHz exceeds it, and 1000 MHz corresponds to higher-category cables designed for greater bandwidth.
