Fibreoptics, also known as optical fibres, are thin, flexible strands of glass or plastic that transmit light signals over long distances with minimal loss of signal quality. They are the backbone of modern telecommunications, enabling high-speed data transmission in various applications, including internet connectivity, telecommunications, and cable television.

Optical fibres consist of a core surrounded by a cladding layer. The core has a higher refractive index than the cladding, which allows light to travel through the fibre by a process called total internal reflection. This principle ensures that light signals remain confined within the core, minimizing signal loss and enabling long-distance transmission.

There are two main types of optical fibres: single-mode and multi-mode. Single-mode fibres have a smaller core diameter and are designed to carry a single mode of light, making them ideal for long-distance transmission. Multi-mode fibres have a larger core diameter and can carry multiple modes of light, making them suitable for shorter distances and higher data rates.

Optical fibres offer several advantages over traditional copper wires, including higher bandwidth, lower signal loss, and immunity to electromagnetic interference. These properties make them essential for modern communication networks, supporting the increasing demand for high-speed internet and other data-intensive applications.
