division multiplexing technology with a variety of package sizes and wavelength options; it multiplexes optical signals of different wavelengths into a single optical fiber for transmission. The receiving end uses demultiplexing to decompose the signal in the optical fiber into signals of different wavelengths. DWDM has a channel spacing of 100GHz, 200GHz, etc., suitable for long-distance, large-capacity long-distance backbone networks, or super-capacity metropolitan area network core nodes.
