The Main Working Parameters
(1) Working Mode
AGC: Automatic constant gain.
Tips: Please do not modify working mode.
(2) PUMP Switch
DWDM EDFA does not work normally after PUMP closed, please set with caution.
(3) Input Power Alarm Threshold
DWDM EDFA alarms with lower input power than threshold and then does not work normally.
Please do not set this term, lest the device come to error alarm and a ect normal work.
Tips: DWDM EDFA still can work with higher input power than saturated input power. But please note
that in this case the performance problems are at the owner's risk and FS shall not be responsible
or liable for any performance problems of input power alarm threshold adjustment.
(4) Output Power Alarm Threshold
DWDM EDFA alarms with lower output power than threshold and then does not work normally.
Please do not set this term, lest device come to error alarm and a ect normal work.
Tips: DWDM EDFA still can work with higher output power than saturated output power. But please
note that in this case the performance problems are at the owner's risk and FS shall not be
responsible or liable for any performance problems of output power alarm threshold adjustment.
(5) Work Gain
It is the current gain of EDFA card, which is the same as the default gain when output power is lower
than or equal to saturated output power.
(6) Default Gain
It is the default gain of EDFA card, which is generally the same as work gain under normal
circumstance.
Tips: Please do not modify the default gain.
(7) Module Temperature
It is the temperature inside EDFA module box.
(8) PUMP Temperature
