“Optical cable” is a cable that consists of one or more optical fibers that transmit signals using light. Optical fibers are made up of two parts – the core and the cladding. The core is a thin cylindrical rod made of optical glass or plastic through which light is transmitted. The cladding is a thin outer coating that surrounds the core and protects it from external influences.
Optical cables are widely used in telecommunications systems for transmitting data over long distances. Since optical fibers use light to transmit data, this allows for the transmission of large amounts of data over long distances with high speed and reliability.
Optical cables have several advantages over other types of cables, such as copper cables. They are not susceptible to electromagnetic interference, so they are less prone to interference from other electronic devices. In addition, they have higher bandwidth and lower signal attenuation, allowing for the transmission of signals over long distances without degradation in quality.
Optical cables are used to connect devices in communication networks, such as the internet, mobile communication, television broadcasting, and other communication systems. They are also used in medical equipment, aerospace industries, and other fields.
