5.4.6 AlarmEntry Table
The cerent15216EdfaAlarmEntry table is used to display alarm status. The associated table command
provides a summary of all alarms.
Table 5-11
describes the cerent15216EdfaAlarmEntry table variables.
cerent15216EdfaPumpStatusDCVoltage
Integer (0 to

Read-only
DC voltage (*10V)

cerent15216EdfaPumpStatusOutPowerdBm
Integer
(–99999 to

cerent15216EdfaPumpStatusGain

Integer (–9999
to 9999)
Read-only
Gain (*10 dB)
1.
The value of the cerent15216EdfaPumpStatusGain variable should always be around 23 dB. This variable is the internal
amplifier module gain. The cerent15216EdfaPumpStatusGain variable should not be confused with the
cerent15216EdfaConstGainOverallGain variable that is used to set the gain of the ONS 15216 EDFA2. The
cerent15216EdfaPumpStatusGain is the value of the gain of the amplification module only, it does not take into account the
VOA (variable optical attenuator) attenuation. If you try to calculate the gain using the values of the
PumpStatusOutPowerdBm – PumpStatusInPowerdBm you will not get the exact PumpStatusGain value. A more complex
calculation is required to get the gain value. It needs to take ASE (amplified spontaneous emission) into account. This is often
called the amplifier noise. This variable will be more dominant when the input power to the amplifier is low.
