Fiber optic cables are affected by which types of interference?

Fiber optic cables transmit data using light signals rather than electrical currents, which makes them immune to many types of interference that typically affect traditional electrical cables. Electromagnetic interference (EMI) and radio frequency interference (RFI) primarily affect electrical signals and are caused by electromagnetic fields and radio waves, respectively. Since fiber optics rely on light and not electrical signals, they do not experience disruption from these forms of interference. This characteristic allows fiber optic technology to maintain a higher level of signal integrity over longer distances compared to other types of cabling. Therefore, stating that fiber optic cables are not affected by either electromagnetic interference or radio frequency interference is accurate.
