Fiber optic cables need repeaters to boost weak signals over long distances, ensuring reliable data transmission. Signal loss occurs due to attenuation, dispersion, and physical factors like bending, which can degrade data quality. However, the way they achieve this is radically different. Imagine a light signal traveling through miles of fiber optic cables. The farther it travels, the more its. 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. To counteract these effects, amplifiers or repeaters are.
