Optical Fiber Communication is a technology that uses thin strands of glass or plastic, known as optical fibers, to transmit data as light signals. This method allows for high-speed data transfer over long distances with minimal loss of signal quality. The light signals travel through the fibers by reflecting off the walls, a process called total internal reflection. This communication system is widely used in various applications, including internet connections, telecommunications, and cable television. Its advantages include higher bandwidth, faster speeds, and immunity to electromagnetic interference compared to traditional copper cables.
