Chapter 9 Node Reference
9.1.4 ROADM Node
9.1.4 ROADM Node
A ROADM node adds and drops wavelengths without changing the physical fiber connections. A
ROADM node is equipped with two TCC2/TCC2P cards and one of the following combinations:
Two 32WSS cards and, optionally, two 32DMX or 32DMX-O cards
Two 32WSS-L cards and, optionally, two 32DMX-L cards
Two 40-WSS-C or 40-WSS-CE cards and, optionally, two 40-DMX-C or 40-DMX-CE cards
Transponders (TXPs) and muxponders (MXPs) can be installed in Slots 6 and 12 and, if amplification is
not used, in any open slot.
Note Although not required, 32DMX-O can be used in an ROADM node. Cisco TransportPlanner
automatically chooses the demultiplexer card that is best for the ROADM node based on the network
requirements.
Figure 9-11 shows an example of an amplified ROADM node configuration with 32DMX cards installed.
