In fiber optic media, the signals are represented as patterns of light.
Fiber optic cables are made up of thin strands of glass or plastic fibers that are designed to transmit light signals. These signals can be in the form of either digital or analog data.
To transmit data, light is generated by a laser or LED (Light Emitting Diode) source, and then encoded with the digital or analog information.
The light signals travel through the fiber optic cables by bouncing off the walls of the cable through a process called total internal reflection.
The patterns of light represent the binary data (0s and 1s) or the variations in the intensity and frequency of the light for analog signals.
These patterns of light can be decoded at the receiving end to retrieve the original information that was transmitted.
