Fiber optics is used for long-distance, and high-performance networking. Optical fibers are usually used in telecommunication services like internet, telephone, and television Optical fibers are used most often as a means to transmit light between the two ends of the fiber and find wide usage in fiber-optic communications, where they permit transmission over longer distances and at higher bandwidths (data transfer rates) than electrical cables In fiber optic communication, data is transmitted from the source to the destination by sending light pulses through optical fibers. It changes electrical pulses to light signals and vice versa for communication. Fiber optic communications are preferred when a huge amount of data needs to be transmitted across large distances Optical Fiber Communication is the method of communication in which signal is transmitted in the form of light and optical fiber is used as a medium of transmitting those light signal from one place to another.

A laser is a device that produces optical radiation by the process of optical amplification based on the stimulated emission of electromagnetic readiation. Laser was developed in 1960. Invention of Laser is one of the major milestones in the history of fiber optic communication. Theodore H. Maiman at Hughes Laboratory invented the first Laser. Fiber optic communication is not new - it was invented by Alexander Graham Bell in 1880 for the Photophone. The photophone carried sound on a beam of light. The Photophone didn't catch on because it didn't work when it was cloudy. Here is a bit more on the history of fiber optic communication as itstarted to become more practical
