3.12 Point-to-Point 16-Channel Protected DWDM Link
The example in the previous section can be extended by subtending an 8-Channel DWDM Expansion tray
off of the expansion port of each 8-Channel DWDM Base tray. As shown in Figure 3-57, the 8-Channel
DWDM Expansion trays, like the Base trays, consist of two unit types, a Mux and a Demux. The Mux
multiplexes eight DWDM wavelengths and the Demux de-multiplexes the same eight DWDM wave-
lengths into/out-of a single ‘common’ port. In the case of the Expansion filter trays, the Common port is
connected to the Expansion port of the corresponding base unit. When deployed back-to-back the Mux
and Demux terminal multiplex devices allow full-duplex transmission of up to sixteen OC-48/OC-192 sig-
nals.
