CWDM MUX
CWDM MUX (Coarse Wavelength Division Multiplexer) is an optical communication device used to combine multiple optical signals with coarse wavelength spacing (typically 20 nm) into a single fiber for transmission. Utilizing low-complexity optical technologies such as thin-film filters or fiber Bragg gratings, it enables cost-effective and low-power multi-wavelength multiplexing. Supporting 18 ITU-standard wavelength channels (1271-1611 nm), it features wide channel spacing, low temperature sensitivity, high stability, minimal insertion loss, and low inter-channel crosstalk, making it suitable for short-distance, medium-low speed transmission scenarios like metropolitan area networks and enterprise access layers. Paired with DeMUX, CWDM MUX is widely adopted in networks with limited fiber resources and cost-sensitive deployment requirements, complementing DWDM technology to balance performance and cost efficiency.
