When troubleshooting possible generic fiber cuts, the recommended first step is to: 1. Review alarms at nodes where power loss occurs.
What is the next recommended step?
Options:
A.
Review PM data to determine if the problem is intermittent.
B.
Perform network power traces to attempt to determine the point of power loss.
C.
Monitor amplifier total power in/out to isolate the direction of a possible cut.
D.
Review EPT design for calculated span loss.
Answer:
B

Explanation:
When troubleshooting possible generic fiber cuts, the recommended first step is to review alarms at nodes where power loss occurs. This can help identify the location and extent of the fiber cut and the affected services. The next recommended step is to perform network power traces to attempt to determine the point of power loss. Network power traces are graphical representations of the optical power levels along a span or a path. They can be used to compare the measured power levels with the expected power levels and to pinpoint any significant deviations or drops that indicate a fiber cut. The other options are incorrect because they either do not help locate the fiber cut or are not as effective as network power traces.
