4 Channels CWDM OADM Modules Duplex West & East Link
GEZHI's 4 Channels CWDM OADM Modules Duplex West & East Link are designed for Static and ROADM based systems. The 4 Channels CWDM OADM Modules Duplex West & East Link are Course Wave Division Multiplexing (CWDM) Optical Add/Drop Multiplexers (OADM). This 4 Channels CWDM OADM Modules Duplex West & East Link add (multiplex) and drop (demultiplex) selected channels, or wavelengths, on both directions of a CWDM common fiber link. Using this modules of GEZHI, network designers can add new access points anywhere on a CWDM network, without impacting the remaining channels traversing the network. Access points can be added to linear, bus, and ring networks, where the dual-direction ring design provides redundant protected architecture.
