What are optical fibres primarily used for?

Optical fibres are primarily utilized for transmitting light due to their ability to transmit data over long distances with minimal loss. These fibres consist of a core surrounded by a cladding that has a lower refractive index, allowing light signals to be reflected internally and travel through the fibre without significant attenuation. This property makes optical fibres essential for telecommunications and networking, where they facilitate high-speed internet connections and digital communications. The efficiency of light transmission through these fibres surpasses that of traditional copper wires, which suffer from higher resistance and energy loss. Consequently, optical fibres are a crucial technology in modern communication systems, enabling the rapid transfer of information across various platforms.
