In general, the optics is a branch of physics (science) that deals with the nature, the behavior and properties of light. Optics is the study of the interaction of light with matter. It is also known as the sub-field of electromagnetism because scientifically, light is an electromagnetic wave. Optics of Applied Sciences are often Optical Engineering. Classical optics and modern optics are the two major categories of optics. Fiber optics is one of the main branches of optics, which are very popular in those days.
The transmission of data over fiber is based on the principle of total internal refraction. The data are on the light. That may sound weird, but you will be surprised to learn that more than half of technology is based on the concept and function of the optical fiber. Telephone, radio and television are the most common gadgets that use this technology too.
Unlike the copper wires, there is no chance of electric shock in the case of optical fibers. Glass, the copper over time. Instead of copper wire, a series of threads made of glass (in the form of cable) is used to transmit signals and data in a modular way. It is true that fiber-optics, the traditional copper cable completely glass, very expensive. Can not be used as domestic cable for transmission of electricity and other signals.
Optical fibers are more resistant to external disturbances. Are lighter and thinner. Therefore, they transmit data in digital form as an analogue form. Fiber optics has led to the conversion of all electronic means of transmitting signals in digital form.
Apart from telecommunications, fiber optics is a boon in the medical and industrial applications. In the medical field, the optical fiber is used in many devices such as endoscopes and other high-tech applications. It is assumed that the fiber is ready to revolutionize the medical technology and breakthrough in this field. Organized and high-tech automatic toll traffic and are very useful application of fiber optics.
The Internet and fiber optic cables are inextricably linked, since the optical fibers, the high capacity and high bandwidth.
