he main difference between T568A and T568B cabling standards is that the green and orange cables are interchanged12. T568A is designed for backward compatibility with older telephone wires, while T568B is designed for better signal isolation and noise protection for newer networking systems and products3. T568A is used in blue cables, and T568B is used in green cables1. The standards use the same cable connectors3.

In this situation, the MOST cost-effective cable medium that would not sacrifice system performance would be B. Shielded Cat 6. Electromagnetic interference (EMI) can disrupt network connectivity by interfering with the signals transmitted over network cables. Shielded Cat 6 cables are designed to provide protection against EMI by incorporating a layer of shielding material around the cable’s conductors. This shielding helps to prevent EMI from interfering with the signals transmitted over the cable.
