6. Optical Fibre Dispersions and Future Contributions on Electro-optic Modulator System Optimizations

In short, this work starts with a brief introduction in Chap. 1 about all general types of dispersion in fibre medium. Estimation and prediction of limitations caused by dispersion are essential considerations in designing any optical system. Hence, in the subsequent chapters, an automated system has been designed for measurement and characterization of dispersion. Chapter 2 discusses about the fundamental theory of dispersion and also the cause factors behind it. Appropriated electrical and optical devices with various functions were assembled for dispersion characterization purpose, and their optimum operating conditions have been studied in Chap. 3. The design of the system and the interlinked communication and control among programmable devices are illustrated in Chap. 4. The employed algorithms for the purpose of controlling, measuring and indexing results are also described in Chap. 4. Final measurement results are discussed practically and theoretically in Chap. 5.
