Figure 10-8 Mesh Network
In a multiring mesh network (Figure 10-9), several rings are connected with four-degree or eight-degree 
mesh nodes. The intermediate ROADM nodes are equipped with MMU cards. All wavelengths can be 
routed among two or more rings using a 40-WXC-C card without any optical-electrical-optical (OEO) 
regeneration. As in a native mesh network, is possible to combine 40-WSS-C/40-WSS-CE , 40-WXC-C, 
and 32WSS cards in the same multiring network without impacting system performance. For nodes 
equipped with 32WSS cards, maximum system capacity is limited to 32 channels. A terminal node is 
connected to a multiring node as a spur. 
For information on node configurations for both native mesh and multiring networks, see the 
“9.4  Configuring Mesh DWDM Networks” section on page 9-30.
