Dense wavelength-division multiplexing (DWDM) refers originally to optical signals multiplexed within the 1550 nm band so as to leverage the capabilities (and cost) of EDFAs, which are effective for wavelengths between approximately 1525–1565 nm (), or 1570–1610 nm (). The main components include optical transmitters (converting electrical signals to light), multiplexers (combining wavelengths), optical amplifiers (boosting signals), demultiplexers (separating wavelengths), and optical receivers (converting light back to electrical signals). Commonly used optical sources include laser diodes, semiconductor lasers, and fiber lasers. 2 Passive Components - The 2x2 Fiber Coupler - Scattering Matrix Representation - The 2x2 Waveguide Coupler - Mach-Zehnder Interferometer Multiplexers - Fiber Grating Filters 10. Each wavelength carries a discrete data stream at speeds up to 100 gigabits per second, creating these key components: WDM technology comes in three primary variants based on channel spacing and capacity: WDM networks rely on specialized optical components to transmit multiple wavelengths of light.
