17.1.4 ROADM Node
A reconfigurable OADM (ROADM) node allows you to add and drop wavelengths without changing the
physical fiber connections. ROADM nodes are equipped with two 32WSS cards. 32DMX or 32DMX-O
demultiplexers are typically installed, but are not required. Transponders (TXPs) and muxponders
(MXPs) can be installed in Slots 6 and 12 and, if amplification is not used, in any open slot. Figure 17-8
shows an example of an amplified ROADM node configuration.
Both 32DMX-O and 32-DMX cards can be used in ROADM nodes. Cisco MetroPlanner automatically
determines at ROADM Node level which Demultiplexer to use based on the overall Network design.
Note Both 32DMX-O and 32DMX cards can be used in an ROADM node. Cisco Metroplanner automatically
chooses the demultiplexer to use for the ROADM node based on the overall network requirements.
