Here is a book which makes modern optical-fiber communication systems easy to understand. It gives you an up-to-date, comprehensive overview of the principles and operation of present-day optical-fiber communications, without the use of advanced mathematics. Starting with the nature of information, it goes on to explain all the ideas behind information measurement, signals, digital coding, modulation, optical transmission along fibers, optical detectors, demodulation, system design, networking and non-linear optics. More advanced topics bring you up-to-date with recent developments.
