The CWDM Mux & Demux Module is a passive wavelength-division multiplexing device designed to combine and separate multiple optical channels over a single fiber link. Based on thin-film filter technology and micro-optical packaging, the module supports CWDM transmission across the 1260–1620 nm operating wavelength range with 20 nm channel spacing.
