Optical fibers are not immune to ________(a) electronic disturbances(b

1.	Optical fibers are not immune to ________(a) electronic disturbances(b) magnetic disturbances(c) ambient light interference(d) electromagnetic disturbancesThis question was posed to me in an online quiz.I want to ask this question from Optical Fiber Sensors topic in chapter Physiological Transducers of Biomedical Instrumentation
Answer» Correct choice is (c) ambient light interference To explain: Optical FIBRE sensors are non-ELECTRICAL and hence are FREE from electrical interference usually associated with electronically based sensors. Ambient light can interfere. Consequently, the sensor has to be applied in a dark environment or must be optically isolated.
