Another key characteristic of fiber optic cables is their resistance to interference. Since optical signals are unaffected by electromagnetic fields, fiber optic cables can transmit data reliably even in environments with strong electromagnetic activity-such as near high-voltage transmission lines or within factory workshops. Furthermore, the fiber itself is an insulator and does not generate sparks, making it safer than copper cabling in flammable or explosive environments. These attributes have led to the widespread use of fiber optic cables in specialized fields such as industrial control, military communications, and medical equipment.
