DWDM Fundamentals, Components, and Applications

Summary: There will be a need for this research soon
Review: When Wavelength Division Multiplexing was first deployed on fibre routes, it seemed awesome! That a tiny glass fibre could transmit so much. It made copper obsolete, if it wasn't for the cost of the last kilometer to many end users.

How could we ever fill such a wide pipe? Well, actually, usage increased, quarter after quarter. And so did progress in the fibre field, as shown in this book. Now we have DWDM. Ever more capacious fibre. Some readers may query the worth of this research described here. After all, with the telecom crash, and the huge overbuilding of fibre capacity worldwide, what is the point of ever more gains? Shouldn't Laude and the rest of his ilk just declare a moratorium for ten years, say, till usage catches up?

Not so. The current installed fibre, including the dark fibre, will barely suffice when viewing or sending video becomes common over fibre. Even with advanced software multicasting to minimise the bandwidth usage, one can expect usage to just keep growing.
