CWDM 1,2 Channel Optical Add-Drop Multiplexer

CWDM 1,2 Channel Optical Add-Drop Multiplexer(CWDM) 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.

The products are Telcordia GR-1221/1209-CORE qualified, and RoHS compliant.
