High-Order Modulation for Optical Fiber Transmission available in PDF, EPUB and Kindle. Catering to the current interest in increasing the spectral efficiency of optical fiber networks by the deployment of high-order modulation formats, this monograph describes transmitters, receivers and performance of optical systems with high-order phase and quadrature amplitude modulation. In the first part of the book, the author discusses various transmitter implementation options as well as several receiver concepts based on direct and coherent detection, including designs of new structures. Hereby, both optical and electrical parts are considered, allowing the assessment of practicability and complexity. In the second part, a detailed characterization of optical fiber transmission systems is presented, regarding a wide range of modulation formats. It provides insight in the fundamental behavior of different formats with respect to relevant performance degradation effects and identifies the major trends in system performance.

Optical Fiber Telecommunications VIB available in PDF, EPUB and Kindle. We provide on overview of fundamental technologies and recent challenges on extremely higher-order quadrature amplitude modulation (QAM) such as 256–1024 levels, toward the realization of an ultrahigh spectral efficiency approaching the Shannon limit. Key components required for such a higher-order QAM transmission are described in detail, including a coherent light source, an optical phase-locked loop, an IQ modulator, and a digital demodulator. We also present recent demonstrations of single-carrier 1024 QAM, 256 QAM-OFDM, and OTDM-RZ/32 QAM transmissions realized with these fundamental technologies.

This book was released on 2020-07-06. Digital Signal Processing In High-Speed Optical Fiber Communication Principle and Application available in PDF, EPUB and Kindle. This book presents the principles and applications of optical fiber communication based on digital signal processing (DSP) for both single and multi-carrier modulation signals. In the context of single carrier modulation, it describes DSP for linear and nonlinear optical fiber communication systems, discussing all-optical Nyquist modulation signal generation and processing, and how to use probabilistic and geometrical shaping to improve the transmission performance. For multi-carrier modulation, it examines DSP-based OFDM signal generation and detection and presents 4D and high-order modulation formats. Lastly, it demonstrates how to use artificial intelligence in optical fiber communication. As such it is a useful resource for students, researches and engineers in the field of optical fiber communication.
