Herc - my answers:
Are the DWDM's the devices that break up light into all the differenct wavelengths?
Ans. Yes.
How many different wavelengths are the light be broken down into?
Ans. Today, by LUMM, into 4, 8, 16, 32, 40, etc. up to 128 wavelengths. But to start 4, 8, 16 and 32, I believe, will be the choices.
How often do the DWDM's have to be spaced along the fiber optic lines?
Ans. At the beginning and the end. In between are devices called add/drops which do just that, add a wavelength and/or take off a wavelength. LUMM is developing those and other devices, on chips, at this moment.
If demand for fiber goes down as some are anticipating then will there will less need for DWDM's?
Ans. No one I know or read suggests the demand will go down. Just the opposite. But should the fibers not be installed there will be a corresponding drop in the need for DWDMs.
One wavelenght per fiber will be enough with slow demand?
Ans. We passed that point of one wavelength/fiber 5 years ago. Please get up to date on what the present demand is.
