Fibre optic technology uses thin strands of glass or plastic, known as optical fibers, to transmit data as light signals. This method allows for high-speed communication over long distances with minimal loss of signal quality. It is commonly used in telecommunications, internet connections, and cable television. The core of a fibre optic cable is surrounded by a layer called cladding, which reflects light back into the core, ensuring that the signal travels efficiently. Fibre optics are preferred over traditional copper wires because they can carry more data at faster speeds and are less susceptible to interference from electromagnetic signals.
