This book discusses the current state of Fiber-to-the-Home. It discusses societal impacts, cost issues, protocol architectures, underlying technologies, and deployment.The book does a good job of discussing all of these aspects of FTTH, except for the underlying technologies. The author attempts to provide more than a rough overview of the underlying technologies (i.e., lasers, photodiodes, splitters/couplers, etc.). Unfortunately, it is best to either give a high level description of these components or delve deeply into the physics of the devices. In my opinion, there is no appropriate middle ground.A note on the writing in the book. The language in quite a few instances is a little awkward. The book is also full of typographic errors.My overall comment would be that this book provides valuable insight into the state of FTTH as of 2005.
