Key parameters of wavelength division multiplexer include

Wavelength division multiplexers (WDMs) combine and separate multiple optical signals on different wavelengths, with key parameters including channel spacing, insertion loss, crosstalk, and wavelength range.Core CharacteristicsMultiplexing and Demultiplexing: WDMs use a multiplexer (MUX) to combine multiple optical signals of distinct wavelengths into a single fiber and a demultiplexer (DEMUX) to separate them at the receiver, enabling simultaneous transmission of multiple data channels over one fiber without interference . Channel Spacing:Dense WDM (DWDM): Narrow spacing of 0.4–0.8 nm (50–100 GHz) in the C-band (1530–1565 nm) or L-band (1565–1625 nm), supporting 40–96 channels .Coarse WDM (CWDM): Wider spacing of 20 nm, covering 1270–1610 nm, typically supporting up to 18 channels . Insertion Loss: Typical insertion loss for high-quality WDMs is
