OPROOR (Optical power received out of range)
The OT port has detected a received optical power out of range at OCH layer. This defect
indicates that local port has detected that the input optical power is lower or higher than
specified value.
This may be caused by the following reasons:
• Damaged or dirty fiber connected to the local receiver
• Damaged or dirty receiver inside pluggable module
• The received power may not be within the acceptable range on local port input
• Power level out of range on the associated OCh trail
Severity Major
Service affecting? Yes
Applicability 11STAR1
This procedure details the corrective action for an OPROOR against the OT port. At the
end of each step wait to see if the fault clears. If not, continue with the next step.
...................................................................................................................................................................................................
1
Retrieve power level reading on the local port.
...................................................................................................................................................................................................
2
If input power level is lower or higher than the required on the port, identify the
associated OCh trail and verify the power levels along the OCh trail.
...................................................................................................................................................................................................
3
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 OPROOR condition.
...................................................................................................................................................................................................
4
Clean the fiber.
...................................................................................................................................................................................................
5
If cleaning the fiber does not clear the problem, replace the fiber.
...................................................................................................................................................................................................
6
Clean the input port of the OT. If the port is pluggable module, replace the module.
