How are bits represented on fiber optic cable?

Bits are represented on fiber optic cables as pulses of light. This technology utilizes light to transmit data, with the presence or absence of light indicating the binary values of 1s and 0s. When a light signal is sent through the fiber, the intensity or duration of the pulses can change to convey different pieces of information. The clarity of light transmission through fiber optics allows for high-speed data communication over long distances with minimal signal degradation.

Other methods, like electrical signals, magnetic fields, or RF waves, do not apply to fiber optic technology, which is specifically designed for light transmission. Fiber optics utilize total internal reflection to maintain the light signals within the fiber strands, making them highly efficient for data transfer compared to other media.
