A safe and reliable aircraft fuel gauging system which eliminates the need for electrical wiring to transmit electrical signals into and out of the fuel tank of an aircraft. The fuel gauging system utilizes at least one light source to generate input light signals which are delivered to a plurality of probes multiplexed on a fiber optic element. The same, or a separate, fiber optic element transmits the probes' output light signals to a light detector located externally of the fuel tank. Each probe includes a photoelectric conversion device, an LC resonant circuit, and a magnetooptic device for generating the responsive output light signal to the input light signal. Based on the output signal form the probes, the light detector determines the level of fuel in the tank.
