Multiplexers/demultiplexers and interleavers combine and separate wavelengths in DWDM (dense
wavelength division multiplexed) systems. Vendors are divided according to technology type: thin-film filters (TFFs),
Fiber Bragg Gratings (FBGs),
Arrayed Waveguide Gratings (AWGs), and bulk grating-based devices.
