Which statement best describes a key advantage of fiber optic cabling for inter-building links?

Explanation:
Fiber optic cabling transmits data as light inside glass or plastic, so there is no electrical conductor carrying the signal. External electromagnetic fields from power lines, motors, or RF transmitters don’t couple into a light signal, which means the link stays clean and stable. This immunity to EMI and RFI is especially valuable for inter-building links, where cables may run near electrical infrastructure or through environments with many sources of interference. While fiber also offers high bandwidth and long-distance reach, the most impactful advantage in this scenario is its limited susceptibility to EMI/RFI, ensuring better signal integrity across challenging installations.
