Which cable type includes additional shielding to minimize electromagnetic interference?

• A. Twisted pair
• B. Fiber optic
• C. Coaxial cable
• D. Shielded cable

Answer: (D)

The choice of shielded cable is appropriate because this type of cable includes an extra layer of shielding, which serves to significantly reduce electromagnetic interference (EMI). Shielding can be made from various materials, including foil or braided wire, which surrounds the inner wires. This layer protects the signals inside the cable from external electromagnetic noise and can also prevent the signals from leaking outside. In environments where electrical noise is prevalent, such as industrial settings, using shielded cables can ensure a more reliable and clearer signal transmission by minimizing disruptions caused by EMI. This makes shielded cables especially valuable in high-frequency applications or where cables run alongside power lines, machinery, or other sources of interference.
