FDM IS USED FOR ANALOG SIGNALS GENERALLY FOR THE SIGNALS
TRANSMITED THROUGH TWISTED PAIR CABLE.
WHILE
WDM IS USED FOR SIGNALS TRANSMITTED THROUGH OPTICAL FIBER
CABLES.
BOTH ARE SAME BUT USED IN DIFFERENT AREAS.

in fdm data transmitted based on the particular frequency
and in wdm data transmitted based on the particular wavelength .
fdm is used in twisted pair cable and wdm is used in fiber
optic cable .

Answer
# 4
their is no difference between FDM and WDM because wavelenth is inversly proportional to frequency. but generally when we are working on optical domain then we consider WDM because

i) we have limited source to genrate light using LED or LASER. using this we can genrate light easily and then passthourgh prism to get different wavelength. we can not genrate such high frequency.

ii) to analysis of such high frequency in CRO is not possible that why we are using WDM when we r working on Optical domain
