Polarity defines direction of flow, such as the direction of a magnetic field or an electrical current. In fiber optics, polarity is directional; light signals travel through a fiber optic cable from one end to the other. A fiber optic link’s transmit signal (Tx) at end of the cable must match the corresponding receiver (Rx) at the other end. So, what is fiber polarity? Fiber polarity could be defined as the direction light signals travel from one end to the other end of an optical fiber cable.
