Fundamentals of Fiber-Optic Systems

Optical fibers guide light rays within the fiber material. They can do this because light rays bend or change direction when they pass from one medium to another. They bend because the speed of propagation of light in each medium is different. This phenomenon is called refraction. One common example of refraction occurs when you stand at the edge of a pool and look at an object at the bottom of the pool. Unless you are directly over the object, as shown in Figure 7.2a, it appears to be farther away than it really is, as indicated in . This effect occurs because the speed of the light rays from the object increases as the light rays pass from the water to the air. This causes them to bend, changing the angle at which you perceive the object. We can obtain an appreciation for the manner by which light flows by focusing our attention upon Snell's Law.
