Presents the technological advancements that enable high spectralΓÇôefficiency and highΓÇôcapacity fiberΓÇôoptic communication systems and networks This book examines key technology advances in high spectralΓÇôefficiency fiberΓÇôoptic communication systems and networks, enabled by the use of coherent detection and digital signal processing (DSP). The first of this bookΓÇÖs 16 chapters is a detailed introduction. Chapter 2 reviews the modulation formats, while Chapter 3 focuses on detection and error correction technologies for coherent optical communication systems. Chapters 4 and 5 are devoted to NyquistΓÇôWDM and orthogonal frequencyΓÇôdivision multiplexing (OFDM). In chapter 6, polarization and nonlinear impairments in coherent optical communication systems are discussed. The fiber nonlinear effects in a nonΓÇôdispersionΓÇômanaged system are covered in chapter 7. Chapter 8 describes linear impairment equalization and Chapter 9 discusses various nonlinear mitigation techniques. Signal synchronization is covered in Chapters 10 and 11. Chapter 12 describes the main constraints put on the DSP algorithms by the hardware structure. Chapter 13 addresses the fundamental concepts and recent progress of photonic integration. Optical performance monitoring and elastic optical network technology are the subjects of Chapters 14 and 15. Finally, Chapter 16 discusses spatialΓÇôdivision multiplexing and MIMO processing technology, a potential solution to solve the capacity limit of singleΓÇômode fibers. ΓÇó Contains basic theories and upΓÇôtoΓÇôdate technology advancements in each chapter ΓÇó Describes how capacityΓÇôapproaching coding schemes based on lowΓÇôdensity parity check (LDPC) and spatially coupled LDPC codes can be constructed by combining iterative demodulation and decoding ΓÇó Demonstrates that fiber nonlinearities can be accurately described by some analytical models, such as GNΓÇôEGN model ΓÇó Presents impairment equalization and mitigation techniques Enabling Technologies for High SpectralΓÇôefficiency Coherent Optical Communication Networks is a reference for researchers, engineers, and graduate students.
