Optical fiber is a thin strand of glass or plastic that uses light to transmit data as signals.
Optical fiber works on the principle of total internal reflection, allowing data to be transmitted over long distances with minimal loss of signal.
The concept of optical fiber dates back to the 1950s, and since then, it has undergone rapid advancements in materials and manufacturing techniques.
Optical fiber has various applications in telecommunications, networking, cable television, medicine, and sensing, offering benefits such as higher bandwidth, longer distances, improved reliability, and security.
