Fibre optic cables provide a high speed method of transmitting large amounts of data over much greater bandwidths than traditional copper cables. They are widely adopted for use in industrial and commercial applications where streaming live data is vital or when long distance applications make copper conductors impractical due to signal loss. Fibre is not affected by EMI (Electro Magnetic Interference) making it ideal for data transmission in electrically noisy environments.

The construction can vary depending on the application and environment. Options include singlemode or multimode transmission in a loose tube or tight buffered fibre design. These are available with a variety of sheath materials and mechanical armours.
