Chapter 19. Principles of Fiber-Optic Transmission
Like Bell's photophone, the purpose of fiber optics is to convert a signal to light, move the light over distance, and then reconstruct the original signal from the light. The equipment used to do this job has to overcome all of the same problems that Bell encountered, while carrying more data over a much greater distance.
In this chapter, you will learn about the basic components that transmit, receive, and carry the optical signal. You will also learn some of the methods used to convert signals to light and light back to the original signals, as well as how the light is carried over the distances required.
In this chapter, you will learn to:
