Digital optical monitoring

The digital optical monitoring (DOM) feature monitors the digital optical media for temperature, voltage, bias, transmission power (Tx), and reception power (Rx). This feature also generates event logs, alarms, and traps for any fluctuations, when configured thresholds are reached.

There are four threshold levels for each of the DOM categories—temperature, voltage, bias, transmission power, and reception power as summarized in the following table:

High
High warning
Low
Low warning

The OS10 DOM subsystem periodically monitors the optical transceivers for temperature, voltage, bias, transmission power and reception power changes and generate event logs, alarms, and traps when their respective values cross the predefined thresholds.

Table 1. DOM Alarms The following table provides a list of DOM alarms, indicates whether a trap is generated for the alarm, and also lists the severity level (major or minor).
Alarm Category	Alarm Name	Traps Generated?	Severity Level
Temperature	Temperature high	Y	Major
	Temperature high warning	N	Minor
	Temperature low	Y	Major
	Temperature low warning	N	Minor
Voltage	Voltage high	Y	Major
	Voltage high warning	N	Minor
	Voltage low	Y	Major
	Voltage low warning	N	Minor
Bias	Bias high	Y	Major
	Bias high warning	N	Minor
	Bias low	Y	Major
	Bias low warning	N	Minor
Power transmission (Tx)	Tx high	Y	Major
	Tx high warning	N	Minor
	Tx low	Y	Major
	Tx low warning	N	Minor
Power reception (Rx)	Rx high	Y	Major
	Rx high warning	N	Minor
	Rx low	Y	Major
	Rx low warning	N	Minor

You can enable or disable the DOM feature, configure traps, and view the DOM status.
