Wavelength Division Multiplexing Technology

Being a technique where optical signals with different wavelengths are combined, transmitted together, and separated again, wavelength division multiplexing (WDM) is mostly used for optical fiber communications to transmit data in several (or even many) channels with slightly different wavelengths. This technique enables bidirectional communications over one strand of fiber, as well as multiplication of capacity. WDM Operating Principle There…
