Fibre optic cables transmit pulses of light rather than electrical signals. Fibre optic connectors are components which terminate the ends of the cables and align the fibres correctly to allow the light to pass through efficiently and successfully. Using connectors offers quicker connection and disconnection than splicing, and high-quality connectors will help reduce any misalignment and will allow minimal light to be lost. Fibre optic connectors are widely used within the telecommunications industry, including in telephone exchanges. They are also frequently found in the IT, oil and gas, aerospace and medical equipment industries.
