Abstract
A fiber optic track circuit including a light source, a fiber Bragg grating (FBG) unit, and a receiver all connected by optical fiber. The light source provides a light via the optical fiber to the FBG unit. The FBG unit is mountable on a portion of a railway system directly effected by the weight of a passing train, and it receives the light beam and provides a reflected beam to the receiver. The receiver then provides a receiver signal based on the reflected beam. And a processor then determines, based on pre-set criteria and the receiver signal, whether to communicate and what to communicate as a track circuit signal to an external device.
