CWDM Module-16channel
Coarse Wavelength Division Multiplexers (CWDM) module come as stand-alone module and as 19” rack-mount assembly, is designed to multiplex (mux) or de-multiplex (demux) optical signals in CWDM systems with multiple channels at an ITU standards defined spacing of 20 nm. CWDM features low insertion loss, wide pass band, high channel isolation and excellent environmental stability and epoxy free optical path. It’s been widely used for many applications, such as CWDM system, Line Monitoring, WDM Network, Telecommunication, Cellular Application, Fiber Optical Amplifier, access Network, and lab research.
