What are Fiber Optic Cables?

Fiber optic cables are used in telecommunication and networking applications. Fiber optic cable uses layers of glass and other materials. It is a glass or plastic material that is used to guide the light along its length. One of its most unique character is that it permits transmission of communication over longer distances and at higher data rates than other forms of communications we have.

The reason we use fibers instead of metal wires in telecommunication networks is because in fibers the signals are able to travel along them without losing much signal. Another unique thing about fiber optics is that electromagnetic interference doesn’t disturb the transmission in case of fibers.
