Which category is described as having the ability to run 10 Gbps over 100 meters maximum?

• A. Cat4
• B. Cat5
• C. Cat5e
• D. Cat6

Answer: (D)

Understanding these categories helps explain why a certain speed is possible over a given distance. Ethernet copper cables are rated to carry certain data rates at specified maximum lengths without excessive signal loss or interference. As you push higher speeds, the required performance of the cable increases, which generally means you need a higher category to maintain reliability over longer distances.

For 10 Gbps Ethernet, Cat6 can support that speed, but only reliably up to about 55 meters. To carry 10 Gbps over the full 100-meter limit, the category designed for that distance is Cat6a. Cat5e and Cat4 are older standards that max out well below 10 Gbps in typical deployments, so they don’t meet the 10 Gbps over 100 meters requirement.

So, the statement tying 10 Gbps to 100 meters best aligns with Cat6a in real-world specs, and Cat6 is the closest high-speed option among the listed choices, though it doesn’t strictly guarantee 10 Gbps at 100 meters.
