D-OADM2x4-Cxx-Cyy/D-OADM2x4-Cxx-Cyy-4C
The D-OADM2x4-Cxx-Cyy is a two-sided 4ch DWDM add/drop filter. The filter has four add/drop ports, one group for east and one for west direction.
The D-OADM2x4-Cxx-Cyy-4C filters are part of a series of filters where the channel passband is wide enough to allow 400G 16QAM signals to be add/dropped by the filter.Channels outside the add/drop channel bands of the H-OADM2x4-Cxx-Cyy-4C filters are glassed through the filter.This intrinsic pass-through bandwidth is from 1264 -1630nm which opens for a wide variety of combinations of LANWDM, CWDM, DWDM and OTDR solutions over the same infrastructure.

Channels outside the add/drop channel bands are glassed through the filter. There are two monitor ports (Mon) that drop about 1% of the transmitted and received signal from the Line ports.
The table below lists the provided variants:

D-OADM2x4-C57-C60 | 195.7 to 196.0 THz |
Ten different versions of the filter are provided. They can be connected in pairs as shown in the figure below ortowards a DWDM Mux/DeMux unit. Note that the Line port shall always face inwards a connection.
