Power Degrade
Low (dBm)
Shows the current value of the optical
power degrade high threshold configured
in the card. This threshold applies only
when the amplifier is active and in
constant power mode.
Power Degrade Low refers to the port’s
Signal Output Power value and is
automatically calculated by the
TCC2/TCC2P when the amplifier is
turned up.
The Power Degrade Low threshold is
automatically linked to the Output Power
Setpoint on the Parameters tab. Changing
the setpoint changes the Power Degrade
Low threshold. The threshold value is
always 2 dB lower than the Output Power
Setpoint.
APC can modify this value based on the
number of OCHNC circuits the amplifier
is managing.
