Description
Options
Port
(Display only) Displays the port number. —
Power Failure
Low (dBm)
Shows the optical power failure low
threshold for the port. The threshold is
calculated automatically when you run
ANS. You can manually change the
threshold. The value must be within the
optical power range that is specified for
the card. (See
Numeric. Display only
Power Degrade
High (dBm)
Shows the current value of the optical
power degrade high threshold. This
threshold applies only when the amplifier
is active and in constant power mode.
Power Degrade High 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 High threshold is
linked to the Output Power Setpoint on
the Parameters tab. Changing the setpoint
changes the Power Degrade High
threshold. The threshold value is always
2 dB higher than the Output Power
Setpoint value.
APC can modify this value based on the
number of OCHNC circuits the amplifier
is managing. See the
Power Control” section on page 18-18
for
more information.
