5.9.2 Installing the 23-Inch DCM Shelf
The dispersion compensation module (DCM) shelf (FC9512SFD3), if needed, provides
dispersion compensation for dense wavelength division multiplexing (DWDM) signals
entering the NE.
Figure 5-8 [p. 5-21] shows the 23-inch DCM shelf (SFD3) with two single-height DCM
units. Figure 5-9 [p. 5-22] shows Issue 03 of the 23-inch DCM shelf (SFD3) with two
single-height DCM units. Issue 03 of the SFD3 DCM shelf supports DCM fiber diversity
mounting units, which allows the routing of fiber to either side of the shelf.
