Fiber-optic cabling is not affected by EMI (Electromagnetic Interference) because it uses light rather than electricity. Shielded Twisted Pair (STP) is a more convenient and cheaper option to reduce the effects of EMI, but it is still susceptible to EMI.
Fiber-optic communication is a method of transmitting information from one place to another by sending pulses of light through an optical fiber. The light forms an electromagnetic carrier wave that is modulated to carry information. Fiber is preferred over electrical cabling when high bandwidth, long distance, or immunity to electromagnetic interference are required. This type of communication can transmit voice, video, and telemetry through local area networks, computer networks, or across long distances.
