What type of signals does fiber optic technology transmit?

Fiber optic technology transmits light signals through thin strands of glass or plastic fibers. This method takes advantage of the principle of total internal reflection, allowing light to travel long distances without significant loss of quality. The light signals can carry vast amounts of information, making fiber optics an efficient medium for high-speed data transmission in various applications, including telecommunications and internet services.

The use of light signals is a key differentiator of fiber optic technology compared to other transmission mediums. This method allows for the transmission of large volumes of data at higher speeds and over longer distances than electrical signals or radio signals typically used in traditional wiring and wireless communication. Additionally, while digital signals can be transmitted using fiber optics (as they are often encoded into light pulses), the primary transmission mechanism remains the light signals themselves.
