Optical mux demux CWDM 1/2/4ch 1470-1610 Add/Drop Multiplexer OADM Module
CWDM/OADM modules are Course Wave Division Multiplexing (CWDM) Optical Add/Drop Multiplexers (OADM). The CWDM/AD modules add (multiplex) and drop (demultiplex) chosed channels, or wavelengths, on both directions (east and west) or one direction (east or west) of a CWDM common fiber link. The technology enables intelligent planning and flexible provisioning of optical services while simplifying the deployment and maintenance of optical networks. Access points can be added to linear, bus, and ring networks, where the east and west ring design provides redundant protected architecture.
Features
Low insertion loss
Wide band
high channel isolation
High stability and reliability
Epoxy-free optical path
Applications
CWDM channel Add/Drop CWDM Add/Drop
