CWDM stands for Course Wavelength-Division Multiplexing. The CWDM method multiplexes optical signals together on one single fiber. To achieve this, it uses different colors (wavelengths) which are combined in a MUX. The device where the optical signals are multiplexed and de-multiplexed is called a MUX or a fiber optical multiplexer or a CWDM multiplexer.
CWDM has 18 wavelengths from 1610 to 1270 with steps of 20nm. The top 8 wavelengths (1610-1470) are the most used and also are not affected by what is referred to as "the waterpeak". This waterpeak causes high attenuation from wavelengths 1370-1410nm on old types of fibers.
Reach Optics offers the Passive CWDM MUX/DEMUX in 8 channels and 18 channels and we also have the full range of CWDM 1G (24dB/32dB/37dB) and SFP+/XFP 10G ER/ZR optics in stock. All of our CWDM MUXE/DEMUX have ABS Box module type, and 19 inch chassis with rack mounts type that the MUX and DEMUX inside.
