What technology transmits information as light pulses along a glass or plastic fibre?

Fibre optics is the technology that transmits information as light pulses along a glass or plastic fibre. This method involves using thin strands of glass or plastic, known as optical fibers, to carry data in the form of light signals. The light pulses travel through the fibers while reflecting internally, allowing data to be sent over long distances with minimal loss of signal quality.

One of the key advantages of fibre optics is its ability to handle large amounts of data at high speeds, making it a preferred choice for telecommunications and internet infrastructure. The use of light rather than electrical signals also means that fibre optic systems are less susceptible to electromagnetic interference, which can affect other types of data transmission technologies. This results in more reliable communication systems with greater bandwidth and higher performance.

In contrast, the other technologies mentioned, like microwave transmission, radio waves, and satellite communication, utilize different mediums and methods for data transmission, such as electromagnetic waves or radio signals, rather than the specific light pulse mechanism characteristic of fibre optics.
