1X2 Coarse Wavelength Division Multiplexer(CWDM) is based on thin film filter technology. They can be used in high-power applications in WDM systems.
1X2 Coarse Wavelength Division Multiplexer(CWDM) is based on thin film filter technology. They can be used in high-power applications in WDM systems. The products adopt hermetic package craft and environmental stability. DK Photonics offers a full range of CWDM Mux-Demux and Optical Add Drop Multiplexer (OADM) units to suit all kinds applications and network solutions. Some most common ones are: Gigabit & 10G Ethernet, SDH/SONET, ATM, ESCON, Fibre Channel, FTTx and CATV.
Our CWDM Mux Demux products provide up to 16-channel or even 18-channel Multiplexing on a single fiber. Due the the low insertion loss is needed in WDM networks, we can also add “Skip Component” in a CWDM Mux/Demux module to reduce the IL as an option.
Standard CWDM Mux/Demux package type include: ABS box package, LGX pakcage and 19” 1U rackmount. The products are Telcordia GR-1221/1209-CORE qualified, and RoHS compliant.
