Description
C-MD-05H/C-MD-05H-L 4CH High CWDM-band filter
The C-MD-H05 is a 4ch high CWDM-band Mux/DeMux with an Extension port.
The four wavelength ports of the C-MD-05H operates on the high CWDM-band channels; 1471/1491nm &1591/1611nm. The wavelength band between these can be utilized for DWDM channels via the Extension port.This is the primary intension with this filter. To fully utilize the high band CWDM channels, the C-MD-09H or C-MD-09H-L is the recommended choice.
Alternatively, the low CWDM-band channels can be added to the Extension port via the C-MD-H08L or C-MD-H08L-L Mux/DeMux modules to provide an 8+4 channel solution. The Extension port can as another alternative be connected to a fiber network carrying a legacy 1300nm channel, enabling the same fiber infrastructure to carry an additional four channels. Figure 6 shows channels supported via the wavelength ports (l-ports) and Extension port.
The figure below shows how the C-MD-05H filters are combined with the 8ch C-MD-08L or C-MD-08L-L filters to provide a 4+8 channel configuration.
The figure above shows the alternative example where the C-MD-05H filters are combined with DWDM channels via theD-MD-16-C21-C36 filters. In the case that optical EDFA amplifiers are required, these are added between the DWDM and CWDM filters so that only the DWDM channels are amplified.
Combined CWDM and DWDM configuration example
The C-MD-05H/C-MD-05H-L; 4ch 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.

C-MD-H05-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. | |||
