Description
C-MD-09H/C-MD-09H-L; 8ch low loss, high CWDM-band filter
The C-MD-09H is an 8ch CWDM Mux/DeMux with an extension port. The eight wavelength ports of the H-MD-H09H operates on the high CWDM-band channels; 1471 to 1611nm. This filter is best used to fully utilize the upper CWDM channels in the region where the SM fiber attenuation is the lowest.
As shown in the figures below, the extension port can be used to add on the low CWDM channel band via the C-MD-04L, C-MD-08L or C-MD-08L-L Mux/DeMux
C-MD-09H channels and potential added low CWDM-band channels
Example with C-MD-09H combined with 8ch CWDM low band filters
The table lists what filters that can be connected to the Extension port.
| PARAMETER | |
Extension port wavelength band H-MD-H09H | 1264 – 1458nm |
Filters matching Ext port | C-MD-04L (CWDM channels 1271 – 1331nm) |
C-MD-08L (CWDM channels 1271 – 1451nm) | |
C-MD-08L-L (CWDM channels 1271 – 1451nm) | |
The table below compares the worst-case (ageing & temperature) link loss of C-MD-09H and C-MD-09H-L at I-temp conditions. Note that C-temp conditions will provide lower losses.

C-MD-09H-L uses a more expensive filter design to provide a lower loss. The selection between the two is a balance between needed loss and cost. | |||
The C-MD-09H/C-MD-09H-L; 4ch low loss, high CWDM-band filter module are mounted in a 1 RU mounting bracket solution where the filter module sizes varydepending on type of filter, i.e. the number of optical ports that are required. The filters are thus not wider thannecessary. The size of the plug-in filter units runs from 35 to 113mm in width and any combination of the filtermodules can be mounted in the 422mm wide slot of the mounting bracket. The 40ch filters are monoliths andhave a full 19” rack width.
