14 Alarms
Name Full name Description
TINT Internal temperature alarm Indicate that the EDFA`s internal
case temperature is out of limits
MODULE_SHUT_TEMP Module automatically shutdown
alarm
The alarm is activated if any single
pump laser diode temperatures
exceed the set value by 2 Celsius
and control electronic automatically
shutdown pump laser diodes.
PTMP Pump temperature alarm The alarm is activated if any single
pump laser temperature is higher
than the software maximum alarm
or less than the software minimum
alarm.
EOL End of life of pump diode alarm The alarm is activated if any single
pump laser current reaches 95% of
its End Off Life value.
The values are noted in “Active
Report Unit” document.
ADI Amplifier Disable alarm The signal present that that the
laser pump diodes power supply is
turned off. The amplifier don`t
amplify now.
The Temperature control power
supply stay turned on.
OPMI Eye-safe Power Control alarm When active, the output power is
set to mute power according to ALS
function. (default 0dBm)
PUMPON Pump diode ON This signal isn`t alarm. This signal
only report that Laser Pump diodes
are active and optical amplifier
amplify input signal.
INLOSS Loss of input alarm The input signal is lower than loss
of input alarm threshold. Alarm
threshold is settable and may be
disabled (set LI to -50.00dBm)
OUTLOSS Loss of output alarm The output signal is lower than loss
of output alarm threshold. Alarm
threshold is settable and may be
disabled (set L0 to -50.00dBm)
