Physics of Total Internal Reflection 

Consider a ray of light passing between two media of different refractive indexes n1 and n2 as shown in figure 3. If n1> n2 the light ray as it passes from one media to the next will bend away from an imaginary line (the normal) perpendicular to the media’s mating surface. Conversely if n1 < n2 then the ray will bend towards the normal. Total internal reflection occurs when n1 > n2 and the incident ray of light makes an angle, Θc, such that it does not enter the adjacent medium but travels along the interface. At angles greater than Θc the ray will be reflected back into medium

The Application of Fiber Optic


Since its invention in the early 1970s, the use and the demand of optical fibre has grown immensely. Today, the uses of fibre optic are quite numerous. The most uses are popular in telecommunications, medicine, military, automotive and industrial. The improvement for this technology still in progress and it will always be upgrade days by days. In our project, we only focused in the application of fibre optic in telecommunication.
The Fibre optic has been used as the medium for telecommunication and networking system because of it flexibility and can be bundled as cables. Fibre optic was able to use for a long-distance communication because of its ability to propagate through the fibre with little attenuation. While in a networking or short-distance communication, fibre optic was saved the space in cable ducts because a single fibre can carry too much data.

History of Fiber Optic


In this new era, we need a technology to improve our life style. We have come out with a new idea than can make our life more efficient that is fiber optics. Fiber optic is the overlap of applied science and engineering concerned with the design and application of optical fibers. The introduction of fiber optic technology has had a dramatic effect on the Communications industry. Generally, this fiber optic is used for transfer data transmitted on a beam of light which is more effective than before.
