WDMmultiplexing
WDM Multiplexing, or Wavelength Division Multiplexing, is a technology used in fiber optic communications that enables the transmission of multiple data streams over a single optical fiber. This is achieved by assigning each data stream a unique wavelength, or color, of light. These different wavelengths are then combined onto the same fiber using a multiplexer. At the receiving end, a demultiplexer separates the individual wavelengths, allowing each data stream to be processed independently.
The core principle of WDM is that different wavelengths of light can travel through optical fiber without
There are two main types of WDM: Coarse WDM (CWDM) and Dense WDM (DWDM). CWDM uses fewer
