2
If power level is low on the DWDM facing port, identify the associated OCh trail and
verify the power levels along the OCh trail.
...................................................................................................................................................................................................
3
Identify the farthest upstream point relative to the far end OTUk port at which power
level falls within the expected range.
...................................................................................................................................................................................................
4
Check the alarms/conditions on the node located in Step 3 or the node immediately
upstream from point identified in Step 4.
...................................................................................................................................................................................................
5
Correct the problem identified in Step 4.
...................................................................................................................................................................................................
6
If all power levels along the OCh trails fall within the target range, locate the fiber
connected directly to receiver of the port which detects SSF condition.
...................................................................................................................................................................................................
7
Clean the fiber.
...................................................................................................................................................................................................
8
If cleaning the fiber does not clear the problem, replace the fiber.
...................................................................................................................................................................................................
9
If the problem is detected on the client port of 11STAR1 OT, and the power level is
within the operating range, check for pluggable module alarms.
...................................................................................................................................................................................................
10
Replace the pluggable module.
