Fibre Optic Network What is a Fibre Optic Network? A fibre optic network uses optical fibres to transmit data as light signals, offering unparalleled speed, bandwidth, and reliability for communication. Explanation Fibre optic networks are less susceptible to interference than traditional copper cables and can transmit data over long distances without degradation. They are commonly used for internet services, telecommunications, and data centres. Practical Example of a Fibre Optic Network A telecommunications provider uses a fibre optic network to deliver high-speed internet and phone services to customers.
