Detailed explanation-1: -Fiber cable is immune to EMI and RFI. Answer: True. Fiber cable is not susceptible to signal loss from electromagnetic interference (EMI) or radio frequency interference (RFI).
Detailed explanation-2: -The interference happens with coaxial cables but not with fiber optic cables as the signal transmission occurs through light, and not current. It opens the potential of fiber optic cable installation in places where EMI can block signal transmission. Fiber optics are ideal for data transmission between computers.
Detailed explanation-3: -Fiber Optics is immune to any magnetic interference. Deployment within electrical motors, transformers or MRI bore will not affect the optical signal.
Detailed explanation-4: -Both glass optical fiber and plastic optical fiber offer complete immunity to interference like this, because they are both made of electrically insulating materials.
