Fiber Optic Test and Measurement

This books stands heads and shoulders above anything else written so far on the test and measurement of fiber optic systems and components. The other reviewers have given details about the books content, so I'll say why I liked the book.Two main reasons: 1) The authors go into detail regarding how different instruments work from physical principles. Such an understanding is useful in understanding a device's (and measurement's) accuracy and validity.2) The practical tips and explanations on how to make measurement alone make this an essential reference. This book neatly compliments theoretical books and papers by explaining how the typical measurements you may read about in a journal article are made and the underlying issues that contribute/take away from a measurement's efficacy/accuracy.Some of my colleagues say that because this book was written by HP people and the examples shown involve HP instruments, this book loses some value. If so, this loss is miniscule.Most photonic test instruments, HP or not, work on more or less the same principles. Whether or not you own HP instruments, you will find this book an invaluable reference.

While fiber optic technology has advanced at a breakneck pace, the core fundamentals of lab measurements for photonics remain the same. This book gives you a very straightforward introduction to the most important ones, along with the basic physics as to why we do it this way. This is not really a quick introduction or simple overview for new lab technicians. This is meant as a reference that many people can use at different levels: the experienced techs, the junior engineers, as well as the more senior R&D scientists. Optical device manufacturers reference this book in their test data reports to explain how they were measured. This would be an excellent primer for junior/senior year college lab courses in physics or engineering.The contents remain very relevant even though it was published 25 years ago (we used it just a few weeks ago for laser linewidth measurement techniques). I give it 4 stars only because my edition is a little dry and monochromatic, and may not be as fun to work with as textbooks with nicer pictures and colors.-c

Good textbook

Extremely useful book for working in fiber optics labs

Great book.

This is probably the most complete, accurate, and authoritative book I've seen that is devoted specifically to the science of testing fiber-optic systems and components.The book begins by reviewing basic fiber-optic communications systems. It summarizes basic ideas in communications theory, characteristics of optical fiber, optical amplifiers, optical repeaters, O/E converters, and wavelength-division multiplexing. The first chapter also contains some useful background information about bit-error rates and waveform analysis. There are simple descriptions of multimode fiber, and basic explanations of things like numerical aperture, chromatic dispersion, and polarization characteristics of optical fiber. There is also some review material on active components such as Fabry-Perot lasers, distributed-feedback lasers, vertical cavity surface-emitting lasers, electrooptic modulators, and LEDs. The first chapter ends with a review of time and frequency measurements in photonic networks.The material in the first chapter is pretty broad, and some of it is rather shallow. It's not really a good place to go for a primer on photonic networks, but the first chapter does help the reader review key concepts and ideas that are important in the book's later developments.With the review completed, the book launches into detailed discussions about different types of measurements made in fiber-optic networks and on fiber-optic components. Generally, each chapter deals with a separate topic, and is written by a different author.Chapter two discusses the nuances of making optical power measurements. While some may think that such measurements are trivial, Christian Hentschel (the author of chapter 2) does an excellent job of illustrating the precise engineering needed to make the most accurate measurements of optical power. Topics covered include temperature effects, spatial effects, noise, reflectivity, and compatibility with various fiber and connector types.Chapter three is of special interest to anyone working in the field of wavelength-division multiplexing, as it's subject matter deals with optical spectrum analysis. A common theme throughout this book is to describe many of the different ways in which measurements can be performed. True to that theme, Joachim Vobis and Dennis Derickson (the authors of chapter 3) review the various ways in which spectral analysis can be performed. These include tunable filters like the Fabry-Perot interferometers as well as diffraction-based OSAs. The authors clearly prefer the grating OSA, and most of the chapter deals with specific nuances that must be considered in making such and instrument perform properly. Chapter four is similar to chapter three - it deals also with optical spectrum analysis. Chapter four, though, is devoted exclusively to the subject of wavelength meters that make spectral measurements using a Michelson interferometer and stabilized internal light source.Chapter five covers high-resolution optical frequency analysis. Chapter 6 deals with polarization measurements, including a review of the Jones calculus and a nice explanation and description of the Stokes parameters and Poincare sphere. Chapter 7 describes intensity modulation and noise characterization of optical signals. Chapter 8 covers analysis of digital modulation on optical carriers, including some nice material on bit-error rates, eye-diagram analysis, mask measurements, and jitter analysis. Chapter 9 has some good information on insertion-loss measurements (another of those underestimated problems). Chapter 10 has a good review of optical time-domain reflectometers (OTDRs) used in testing components, while chapter 11 explains the use of OTDRs in making measurements on optical fiber. Chapter 12 covers dispersion measurements, including both chromatic dispersion and polarization-mode dispersion. The last chapter explains the tests used to characterize erbium-doped optical fibers (EDFAs). This last chapter, especially, is well worth reading, though I found some of the test descriptions a little hard to follow.The book ends with three very useful appendices. Appendix A is devoted to noise sources in optical measurements, appendix B to nonlinear limits for optical measurements (a must for anyone working with DWDM systems) and appendix C has some practical information regarding the care of optical connectors.The book covers a tremendous amount of information. Its 642 pages are jam packed with just about everything you ever wanted to know about photonic test and measurement. And what it does not cover is usually described in excruciating detail in the complete list of references at the end of each chapter.There are plenty of equations, but not much mathematical derivation. If you are up on your algebra and calculus you will have no difficulty following anything in this book. Its aim is practicality, and I'd say it hit a bull's eye.The illustrations are done nicely; the explanations are (for the most part) clean, crisp, and concise. This is an excellent book that I highly recommend. I've marked it with yellow pen, dog-eared the corners of the pages, scribbled in the margins, spilt my drink on it at least once, broken the spine, and basically beat it to pieces. That's what you do with the really useful tools - the rest of them just sit on the shelf looking pretty and collecting dust.If you make your living testing photonic systems, you really owe it to yourself to get and read this book.Duwayne Anderson, February 28, 2000

This text is essential for anyone who wishes to test or measure optical sub-components, components, systems, or devices. Dennis lays out the fundamentals of each measurement in an easy to understand format. This is especially useful because this field is growing tremendously and often utilizes people from other fields who lack familiarity with these measurements. This book provides as easy to understand tutorial for people who need to learn these techniques. If you can't measure what you have very well, you don't know what you sent to your customer; and if they can't measure what you sent them, they don't know what they have.

I have known the test and measuring work performed by HP people since 1989, specially the written work from Dr. Christian Hentschel (one of the authors of the book) on lightwave standards and test procedures. After working all these years in the fiber optic and optoelectronics field, I have found this precisious book, and I highly recommend it to every one who needs to work on fiber optic communications. For sure, this book will easly be a first reference on the field.
