4 Channels CWDM Mux Demux , Duplex East CWDM OADM Optical Add / Drop

GEZHI Photonics Duplex CWDM OADM for East-and-West Traffic

The Duplex CWDM/AD modules add (multiplex) and drop (demultiplex) selected wavelengths over dual fiber Duplex CWDM MUX & DEMUX link for East-and-West Traffic.

GEZHI PHOTONICS CWDM OADM ( CWDM/AD) modules are Course Wave Division Multiplexing (CWDM) Optical Add and Drop Multiplexers (OADM). "Add" and "drop" here refer to the capability of the device to add one or more new wavelength channels to an existing multi-wavelength WDM signal, and to drop (remove) one or more channels, passing those signals to another network path.

The CWDM/AD is a passive optical add/drop multiplexer designed for point-to-point, ring, or bus configurations' applications that provides the ideal solution for the increasing bandwidth demand on enterprise and metro access networks and delivers dramatic cost savings to network equipment manufacturers, enabling them to develop metro access systems that are lower in cost, easier to provision and simpler to operate.

Added/dropped channels are interfaced to any of GEZHI PHOTONICS CWDM transceivers on the equipment side, and we also provide optional port configurations such as: Express Port, Monitor Port, 1310nm passband port and 1550nm port for these multiplexers according to customer choice.

NOTE:
Actual layout depends on the chosen connector type as well as other factors. However, the principal scheme stays the sameWe also provide optional port configurations such as: Express Port, Monitor Port, 1310nm passband port and 1550nm port for these multiplexers according to customer choice, When using with 1310nm legacy SDH/SONET, CWDM wavelengths 1270, 1290, 1310, 1330 and 1350nm should not be used. When using with 1550nm legacy SDN/SONET, CWDM wavelengths 1510, 1530, 1550, 1570 and 1590nm should not be used.
