Introduction to Optical Communication Systems
Chapter 1 Introduction to OpticalCommunication SystemsThe purpose of this chapter is to give an overview and a somewhat historical perspective on the field ofoptical communications. The first section of the chapter describes why there are fundamental reasons thatoptics is attractive for use in communications. Indeed, the worldwide telephone network, the world s largestcommunications system , is fiber optic-based. Further, optics is finding progressively more communicationsapplications by the day, not to speak of the numerous sensing applications that are presently being imple-mented. In some areas, optics is being implemented somewhat more slowly than originally predicted. Thisis in great part due to cost. In the telephone network, hardware cost was really not an issue compared to amyriad of other costs such as right of way and cable installation, and the initial implementations were carriedrapidly rather than cost-effectively.
