Primarily used in fiberoptics, but generally applicable, WDM is a way of transmitting more data by separating channels by "color". For example, you can transmit one message with blue light and another by yellow light and another by red light. Then you can separate them at the receiver. More specifically, you can use thousands of very narrow wavelengths in a single fiberoptic cable to increase the communication capacity enormously.

What is the definition of the word 'multiplexing'?
Multiplexing is the process of combining multiple signals over one media line. There are several types of multiplexing: frequency division, time division, and wavelength division.
What is optical fibers used in?
WDM wavelength division multiplexing

Andrea Borella has written: 'Wavelength division multiple access optical networks' -- subject(s): Multiplexing, Wave length, Congresses, Wavelength division multiplexing, Light, Optical communications
What characteristic two modulated signals are guaranteed to differ in wavelength division multiplexing?
color
In wavelength division multiplexing two modulated signals are guaranteed to differ in what characteristic?
Color
Name the various types of multiplexing techniques?
Multiplexing techniques vary widely based on what is being multiplexed. Modern telecommunications use a very wide array of techniques including: TDM - examples: TDMA, T-carrier FDM - examples: DWDM Spatial - example: MIMO Code division - examples: CDMA Phase or polarization division - cable/satellite TV Statistcal - examples: packet mode (STS), FHSS etc etc. This is far from a complete list. I think the question needs to be more specific.
Why amplitude division multiplexing is not used?
