10.8.2.2 System Gain Tilt Compensation With ROADM Nodes
When a ROADM node is present in the network, as shown in Figure 10-24, a per-channel dynamic gain
equalization can be performed. Both gain tilt and gain ripple are completely compensated using the
following techniques:
• Implementing the per-channel VOAs present inside the 32WSS card
• Operating in Power Control Mode with the specific power setpoint designed by
Cisco TransportPlanner
