Optical fiber is used as a medium for telecommunication and computer networking because it is flexible and can be bundled as cables. It is especially advantageous for long-distance communications, because infrared light propagates through the fiber with much lower attenuation compared to electricity in electrical cables. This allows long distances to be spanned with few repeaters.
How does fiber optics work?
Fiber-optic communication is a form of optical communication for transmitting information from one place to another by sending pulses of infrared or visible light through an optical fiber. The light is a

The Physics Behind Fiber Optic Communication: How Light
Unlike traditional copper wires that use electrical signals, fiber optics rely on light to transmit vast amounts of data over long distances with minimal loss.
Which type of light is used in optical fiber
Optical fiber primarily uses infrared light, not visible light, due to lower signal attenuation. Common wavelengths are 1310nm and 1550nm, where silica glass fiber has minimal loss (as low as 0.2 dB/km).
