Extra info for Optical Performance Monitoring: Advanced Techniques for Next-Generation Photonic Networks
Most of the reported OPM techniques have been scattered throughout journals, conference proceedings, and several book chapters. Yet, there is no such book available in the market solely for the discussion of OPM techniques. This book aims to provide comprehensive and in-depth discussions of these advanced OPM techniques, which would be expected to play an important role to facilitate the network management of the next-generation photonic networks. All chapters in this book have been prepared and written by the leading experts and researchers in the OPM field.
The insets present eye diagrams of signal under analysis for OSNR values of 16 and 30 dB. (a) Power at OMS input of 0 dBm and (b) power at OMS input of À5 dBm. Copyright # 2009, IEEE. Dependence of estimated OSNR on OSNRSIG for OSNRREF = 28 dB (□), OSNRREF = 22 dB (Á), and OSNRREF = 16 dB (○). An EDFA is used within the OMS for pre-amplification. The insets present the eye diagram of the signal under analysis for OSNR values of 16 and 30 dB. (a) Power at OMS input of À20 dBm and (b) power at the OMS input of À25 dBm.
Each chapter provides an extensive overview and discussion of various feasible approaches to characterize the respective performance metric. These approaches will be further compared in terms of their technical merits and limitations, as well as their robustness in the presence of other system impairments. The second section comprises Chapters 6–11, which discuss several selected advanced OPM techniques, based on asynchronous amplitude histograms, asynchronous delay-tap sampling, linear xliii xliv Preface optical sampling, radio-frequency pilot tones, electronic digital signal processing techniques, and nonlinear optical effects, respectively.
