Introduction to Dwdm Technology: Data in a Rainbow

It was a pleasant surprise to read this book. I decided to buy the book despite a 3 star rating because I needed to update myself quickly.First I found the book full of nicely done and colorful diagrams that are easy to understand. The author succeeds in explaining fairly complex topics in simple enough words that someone like me with background in science and engineering but work in another field can grasp the concepts quite fast.The book covers a wide range of the latest technologies so it is definitely a useful reference book for people looking to understand optical engineering. It may be too simple for readers who are already knowledgeable in optics. In that sense, I can actually see disappointment by them. But for managers and investors who want to know the subject enough to appreciate the technology-- but not to be an engineer or designer in the field-- this is very useful.I used to write "introductory" books in another technical field with good review from managers and technicians. This book has accomplished that goal for me.

I found the text book very usefull as an overview of the technology. Good and at the point description of the components/hardware used for optical communication. The author has an excellent understanding of the physics governing the technology. Some typos can be found through the text, the author should have the text reviewed more carefully. I recommend the book to anyone who wants to know "how things work".
