Optical Power and Voltage Summary report

Optical Power and Voltage Summary report overview

The Optical Power and Voltage Summary report contains a summary of information about the optical power in dBm, measured at equipment ports. The report provides a table showing Tx power, Rx power, temperature, supply voltage, and Tx bias current.

Limitations

Report limitations include:

The average voltage counter is not part of the hardware resource statistics.
Low voltage threshold and high voltage threshold report inputs are applicable only to DDM statistics and hardware resource statistics.
Periodic counters are used for hardware resource statistics if non-periodic counters are not present in aggregation tables.

Use cases

Troubleshooting—Use the report to confirm that optical power is in the optimum operating range to determine if it is a cause of network impairment.

Prerequisites

The following table describes the aggregation rules that must be enabled and the statistics to be collected. To view the report for granularities other than raw data, the aggregation rules must be enabled; see How do I configure analytics aggregation?.

	Granularity	Aggregation types: None (raw data) Hourly Daily Weekly Monthly
	Region	Select a region.
	Subregion	Only subregions below the top-level region are displayed in the prompt. Objects in the lower subregions are automatically selected when their subregion is selected.
	NE types	Select individual items.
	NE	Select individual items.
	Low voltage threshold	Specify the value using expressions like > or <.
	High voltage threshold	Specify the value using expressions like > or <.
	Logo Position	Choose Left, Middle, or Right. The logo appears on the left on the first page of the report if you choose Left or Middle.
	Show threshold violations only	Select to see threshold violations only.
	Show report output on one page	Select the check box to enable pagination. Note: Using the Show report output on one page option when creating reports as drill-downs may impact report rendering time. Nokia recommends disabling the Show report output on one page option when creating reports.
Drill-down support	Yes—Click on a KPI in a table cell to launch the Details report
