4-Channel +1310nm CWDM Module are 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. CWDM can solve the shortage of fiber and transparent transmission of business, and reduce the cost of network building. With low-cost low power consumption and small compact, it is widely used in metro aggregation and access layer to do transmission on a short time.
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.
