Fiber optics is recognized for its high resistance to electromagnetic interference due to the fundamental nature of how it transmits data. Unlike traditional copper wiring or coaxial cables, which conduct electrical signals and can be susceptible to electromagnetic fields that interfere with those signals, fiber optics uses light to transmit information through glass or plastic fibers. This means that the signals are inherently immune to electrical noise and interference from nearby electrical equipment or radio frequencies.

In practical terms, this quality of fiber optics makes it a highly reliable choice for critical communication systems in aviation and other industries where electromagnetic interference could disrupt performance or data integrity. The ability of fiber optics to maintain signal quality in environments with high electromagnetic activity is a significant advantage, particularly in modern avionics applications.
