What is the primary method of information transmission through optic fiber?

The primary method of information transmission through optic fiber is via photons. Optical fibers transmit data by using light signals, which are made up of photons. When data is sent through fiber optics, the light pulses travel along the core of the fiber, reflecting off the inner walls due to total internal reflection. This allows for very high data rates and long-distance transmission with minimal loss of signal quality.

In contrast, electrical signals are typically used in traditional copper wires, while radio waves and microwave signals are used for wireless communication. These methods do not utilize the unique properties of light and the internal structure of optical fibers, making photons the most effective means of data transmission in this context.
