15.4 Span Loss Verification

Span loss measurements can be performed from the Maintenance > DWDM > WDM Span Check subtab
(Figure
"Span Loss Out of Range" condition is raised when the measured span loss is higher than the maximum
expected span loss. It is also raised when the measured span loss is lower than the minimum expected
span loss and the difference between the minimum and maximum span loss values is greater than 1 dB.
The minimum and maximum expected span loss values are calculated by Cisco MetroPlanner for the
network and imported into CTC. However, you can manually change the minimum and expected span
loss values.
