This book gives readers an independent treatment of all the theory and design criteria needed to design high speed and multi-wavelength optical fiber communication systems. Contains many aspects of fiber optic transmission technologies including waveguide theories, opto-electronic devices and system design? Together, volumes one and two covers all the criteria of the theory and design of high speed and multi-wavelength fiber optic communication systems Because of the balance between a clear description of the theory and scope of practical examples that are relevant, this text is suitable not only for engineers R & D and system designers, but also academics and researchers in the field.
