D-OADM2x2-Cxx-Cyy-4C; DWDM 2-way OADM filter
The D-OADM2x2-Cxx-Cyy-4C is a two-sided 2ch DWDM add/drop filter. The filter has four add/drop ports, one group for east and one for west direction.
The D-OADM2x2-Cxx-Cyy-4C filters are part of a series of filters where the channel passband is wide enough toallow 400G 16QAM signals to be add/dropped by the filter,Channels outside the add/drop channel bands of the D-OADM2x2-Cxx-Cyy-4C filters are glassed through the filter. Note that this intrinsic pass-through bandwidth is from 1460-1620nm, i.e. more narrow than the other filters in the 400G capable filter family.Channels outside the add/drop channel bands areglassed 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：
