		Maximum

	to 9999)

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.

5.4.6AlarmEntry Table

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