Fiber-optic 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 quality. The light signals travel through the fibers by reflecting off the walls, enabling efficient communication. One of the main advantages of fiber-optic communication is its ability to carry large amounts of information simultaneously, making it ideal for internet and telephone services. Additionally, it is less susceptible to interference from electromagnetic signals, ensuring a more reliable connection compared to traditional copper cables.
