A network technician needs to install a cable in a factory environment with a high concentration of heavy machinery, which generates significant electromagnetic interference (EMI). To ensure the highest level of data integrity and prevent signal degradation, which of the following cable types should be used?
Optical fiber cable is the best choice for this environment because it transmits data using pulses of light, making it completely immune to electromagnetic interference (EMI) and radio frequency interference (RFI). Unshielded Twisted Pair (UTP) is highly susceptible to EMI. While Coaxial and Shielded Twisted Pair (STP) offer more protection against EMI than UTP, they are still copper-based and not fully immune. Therefore, optical fiber provides the most reliable performance in high-EMI environments.
