Description
D-MD-09EM-Cxx-Cyy; 8ch DWDM filter
The D-MD-09EM-Cxx-Cyy filters are a series of DWDM Mux/DeMux'es having 8 wavelength ports, one extension port and two monitor ports.
D-MD-09M-C21-C28 logical icons and front plate example
The monitor portstap off about 1% of the transmitted and received line signal.This provides the ability to monitor the channel power levels via a connected Optical ChannelMonitoring (OCM) deviceor an optical spectrum analyzer.
The table below lists the provided variants:
Product number | DWDM channels |
D-MD-09EM-C21-C28 | 1560.61 to 1554.94 nm |
D-MD-09EM-C29-C36 | 1554.13 to 1548.51 nm |
D-MD-09EM-C37-C44 | 1547.72 to 1542.14 nm |
D-MD-09EM-C45-C52 | 1541.35 to 1535.82 nm |
D-MD-09EM-C53-C60 | 1535.04 to 1529.55 nm |
The number of channels can be extended by connecting two or more filters via the Extension ports.

D-MD-08EM-Cxx-Cyy-L; low loss 8ch DWDM filter
The D-MD-09EM-Cxx-Cyy-L are a set of 8ch DWDM filters covering the same channels as the D-MD-08EM-Cxx-Cyy filters, but uses a low loss filter design that provides a much lower loss through the Extension ports. The D-MD-09EM-Cxx-Cyy-L is thus advantageous when cascading multiple filters via the Extension ports.
D-MD-08EM-Cxx-Cyy-4C; 400G 8ch DWDM filter
The D-MD-09EM-Cxx-Cyy-4C are a set of 8ch DWDM filters covering the same channels as the D-MD-08EM-Cxx-Cyy filters, but having a channel passband of 72.5GHz enabling 400Gbps/16QAM signals to be add/dropped. The pass-through (Ext Û Line) has an extra wide band coverage 1264 -1630nm which opens for a wide variety of combinations of LANWDM, CWDM, DWDM and OTDR solutions over the same infrastructure.
The table below compares selected parameters between the D-MD-C08EM-Cxx-Cyy and the low loss version D-MD-C08EM-Cxx-Cyy-L.
