This professional-grade 4-channel CWDM mux demux module delivers ultra-low polarization dependent loss (PDL) performance for demanding bidirectional communication systems. Engineered for 1370-1530nm wavelength range, our dual-fiber CWDM solution provides 4 independent optical channels in single 1U rack space, reducing fiber count by 75% while maintaining <0.5dB ripple uniformity.
The hermetic sealed design ensures stable operation in harsh environments, making it ideal for FTTx deployments and mobile transport networks. With industry-leading >40dB return loss, this CWDM mux demux set significantly outperforms conventional WDM devices in OSNR-sensitive applications.
Package Includes:
1× 4CH CWDM Mux
1× 4CH CWDM Demux
2× Dust caps
Installation guide
Why Choose Our CWDM Solution?
→ Plug-and-play deployment with <15min commissioning time
→ 3-year warranty with lifetime technical support
→ RoHS/REACH compliant eco-friendly manufacturing
CWDM technology uses ITU standard 20nm spacing between the wavelengths, from 1270nm to 1610nm. Our CWDM module has 2 to 18 channels. The central wavelength of each channel is specified to one of the ITU-T grid wavelengths. The CWDM module features wide channel bandwidth (13nm). Its isolation is greater than 30dB for adjacent channels, and greater than 40dB for non-adjacent channels. The module also has high thermal stability to ensure reliable performance under different environment.
