Abstract: A fiber optic communication signal link apparatus for performing fiber optic link communication including a transmitter apparatus and a receiver apparatus coupled by a fiber optic cable. The transmitter is capable of detecting and modulating data that includes at least one of position, light and audio data. An analog voltage signal representing the data is transmitted to the transmitter apparatus wherein the signal is detected, converted to a frequency signal and modulated through the fiber optic cable to the receiver apparatus. Subsequently, the frequency signal is detected, demodulated and converted back to a voltage analog signal in the receiver apparatus.
