How many MHz does the CAT6A cable operate at?

  1. 600 MHz

  2. 250 MHz

  3. 100 MHz

  4. 1 GHz

The correct answer is: 250 MHz

The correct operating frequency for CAT6A cable is 500 MHz, which allows it to support higher bandwidths compared to its predecessors. This frequency range enables CAT6A to handle data rates of 10 Gbps over distances up to 100 meters, making it suitable for high-speed networking applications. In this context, a choice stating 250 MHz corresponds to the capabilities of CAT5e, which typically operates at frequencies up to that limit. Meanwhile, frequencies like 100 MHz or 1 GHz do not accurately represent the operational characteristics of CAT6A. Recognizing the specific frequency bands is essential for understanding the performance and applications of different Ethernet cables in network setups.
