For transmitting data over large distances, fibre optic cable technology has no serious competition. As opposed to most types of electrical cables, fibre optic cables use light instead of electricity to transmit signals. Light is the fastest method of transmitting information/data. Fibre optic cables have the advantage of not being subject to electrical interference therefore you can run cables anywhere and this is why it is so well suited for all underwater/subsea applications.

The main advantages of fibre optical cable are;

  1. Relatively easy to lay over long distance.
  2. Resistance to electromagnetic interference.
  3. Very high bandwidth. There is no match.
  4. These cables have a very small diameter.
  5. Light weight.
  6. Can be also be upgraded for increased bandwidth demand to a point.

Fiber optic transmission is widely used for data transmission and is increasingly being adopted in place of other options because of its efficiency and high transmission capacity. Fiber optic cables have almost entirely replaced traditional copper twisted-pair cable or coaxial cable. As the use and demand for increased bandwidth and greater speed rises, there is no doubt that fiber optic transmission will bring more opportunities and be continuously expanded to serve future demands.
