Book Description
Digital transmission systems are the backbone of modern communication networks, enabling the exchange of information across various media, such as copper wires, optical fibers, radio waves, and satellites. These systems use digital signals to encode, transmit, and decode data, such as voice, video, text, and images. Digital transmission systems have many advantages over analog systems, such as higher capacity, better quality, lower cost, and more flexibility. However, designing and implementing digital transmission systems is not a trivial task. It requires a solid understanding of the fundamental principles, techniques, and standards that govern the operation and performance of these systems. It also requires a familiarity with the various technologies and components that are used to realize these systems, such as modulation, multiplexing, coding, switching, amplification, and synchronization. This book aims to provide a comprehensive and up-to-date introduction to the fundamentals of digital transmission systems, covering both theoretical and practical aspects. It is intended for students, engineers, and researchers who want to learn the basics of digital transmission systems, as well as for professionals who want to refresh or update their knowledge in this field. The book is also important for communication engineers and operators who are involved in the planning, design, installation, operation, maintenance, and troubleshooting of digital transmission systems and networks. The book covers the most common and widely used standards and technologies in digital transmission, such as PCM, PDH, SDH, OTN, WDM, ADSL, GPON, and radio waves. The book also provides the latest information on the evolution and trends of digital transmission, such as liquid OTN, fiber-optic transmission systems, and digital transmission networks. The book helps communication engineers and operators to understand the principles, advantages, limitations, and challenges of digital transmission systems and to apply them to their specific needs and scenarios. The book is organized into eight chapters, each covering a major topic in digital transmission systems. The chapters are as follows: Chapter 1 introduces the importance, motivations, and overview of digital transmission systems, and provides a conclusion and some questions for review. Chapter 2 explains the fundamentals of pulse code modulation (PCM), which is the most common technique for converting analog signals into digital signals. It also describes the structure and signaling of the 2 Mbit/s (E1) frame, which is the basic unit of transmission in many digital systems. Chapter 3 discusses the plesiochronous digital hierarchy (PDH), which is a legacy standard for multiplexing and transporting digital signals over copper wires or optical fibers. It also covers the frame structure, synchronization, signaling, error detection and correction, network architecture, and limitations of PDH. Chapter 4 introduces the synchronous digital hierarchy (SDH), which is a more advanced and widely adopted standard for multiplexing and transporting digital signals over optical fibers. It also covers the general and specific frame structures, multiplexing hierarchy, network and management, network protections, and synchronization of SDH. Chapter 5 presents optical fiber technology, which is the main medium for transmitting digital signals over long distances and at high speeds. It also covers the technical overview, physics of light, and design and protection of fiber optic cables. Chapter 6 explores the wavelength division multiplexing (WDM) technology, which is a technique for increasing the capacity and efficiency of optical fiber networks by using multiple wavelengths of light. It also covers the WDM and optical fiber structure, active and passive optical components, optical amplification, noise calculation, fiber-optic transmission systems, and fiber-optic networks. Chapter 7 describes the optical transport network (OTN), which is a standard for multiplexing and transporting various types of digital signals over optical fibers using a common format. It also covers the OTN fundamentals, multiplexing overview, frame structure, evolution to liquid OTN, and important topics in OTN. Chapter 8 reviews the ADSL modems, GPON fundamentals, and radio waves propagations, which are some of the technologies and phenomena that are related to digital transmission systems. The book also includes two appendices that provide some supplementary information on BIP, SDH Synchronization, OTN protection and more. The book assumes that the reader has some basic knowledge of mathematics, physics, and electronics, as well as some familiarity with communication systems and networks. The book provides clear explanations, examples, figures, tables, and equations to illustrate the concepts and methods of digital transmission systems. The book also provides questions at the end of each chapter to test the reader’s understanding and to stimulate further exploration. The book is written by who is a Doctor of Electrical Engineering, Egypt. Ayman Elmassarawy has a PhD in communication systems and has over 20 years of research and practical experience in the field of digital transmission systems in the field of digital transmission systems.

Book Description
"The book have made an attempt to know and rectify that the phenomenon that takes place against to the light, for the light and of the light. That is known as dispersion. Several dispersion effects or encountered by the pulse of light propagation through a fibre and these acts to spread out of the Pulses in the time domain by changing the shape of the pulse. As a result pulses may be got merged in the previous or in the succeeding pulses became indistinguishable at the receiver end. It is the auto correlation of the optical electrical field with respect to time using the interference pattern created by adding a Wave to a delayed wave. This book deals with that how the interferometer splits an incoming light wave along its path and recombined the light at the output. Finally it is concluded that by this method an increasing the wavelength of a coherence source the polarization mode dispersion is reduced by means of which the speed of the communication of optical signal can be increased through optical fibre"--Preface.
