Title: Mostly useless
Review: Only 70 of the 250 pages are dedicated to DWDM technology directly. Full of conflicting and ambiguous comments. For instance the section on Arrayed Waveguide Grating states in two consectutive comments: >AWG's are temperature sensitive. To eliminate thermal drift... Next Comment: >AWG's operating in the wide temerature range (0-85C) have been reported. Most topics are treated rather lightly. Seems like a book put together in a hurry to cash in on the recent "Fiber" goldrush.
