The operation of each component is discussed individually and the whole structure of a fundamental DWDM system is shown at the end of this blog. DWDM, supports up to 80 simultaneous wavelength channels, with each of the channels only 0.8nm apart. Dense Wavelength Division Multiplexing (DWDM) Definition Dense wavelength division multiplexing (DWDM) is a fiber-optic transmission technique that employs light wavelengths to transmit data parallel-by-bit or serial-by-character.
