The DDM-2000 FiberReach Multiplexer wideband shelf is shown in Figure 3-1
through Figure 3-9. Figure 3-1 through Figure 3-7 show various shelf
configurations. The shelf measures approximately 9.65 inches high by 9.17
inches wide by 13.11 inches deep. Each wideband shelf is a stand-alone entity
with its own fiber cabling and interfaces to the DSX-1, office power, and operations
interfaces. The default configuration provides rear access cabling. Front access is
also an option. Front-access optical connectors interconnect to optical fiber
facilities and facilitate shelf loopback. The optical connectors are mounted on the
optical line interface unit (OLIU) circuit pack faceplate. A DDM-2000 FiberReach
Multiplexer wideband shelf consists of the following:
■
