4ch DWDM Add+Drop Multiplexers in splice/pigtailed ABS module, 100GHz ITU grid, duplex LC/UPC

 

GEZHI DWDM/AD modules are Dense Wave Division Multiplexing (DWDM) Optical Add/Drop Multiplexers (OADM). The DWDM/AD modules add (multiplex) and drop (demultiplex) selected channels, or wavelengths, on both directions (east and west) or one direction (east or west) of a DWDM 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.

DWDM passive OADM modules are protocol-transparent and invisible to both the network and the users, each DWDM passive OADM uses wavelengths that fall within the ITU-T G.694.2 DWDM grid standard from C17 to C61(1563.86~1528.77nm) with 0.8 nm spacing.

Optical add drop multiplexer function

The passive DWDM optical add drop multiplexer (DWDM OADM) sends and receives signals to/from DWDM transceivers installed in the switch. It adds or drops this specific wavelength from the optical fiber and allows all other wavelengths to pass straight through.

Features

 

 

Each fiber pigtails of inputs and outputs are labeled with wavelengths that is used to indicate the wavelengh of the individual DWDM transceivers. There are four holes to fix the pigtailed module with your device.
