Total Output
Power
(Display only) Shows the current power level per
port.
—
Channel Power
Ref.
(Display only) Shows the optical per-channel
signal power setpoint that must be reached at the
amplifier output when gain control is active.
—
Offset Adjusts the Total Output Power unless network
conditions prevent the adjustment, for example the
port is in IS state.
—
Signal Output
Power
Shows the current output power leaving the
amplifier, including the amplified spontaneous
emissions (ASE) contribution.
—
Channel Power
Ref
(Display only) Shows the optical power per channel
leaving the amplifier.
—
Channel Power
Ref
(Display only) Shows the optical power per channel
leaving the amplifier.
—
Power Calib Allows you to manually change the total optical
power going to the amplifiers.
Numeric
Gain (Display only) The current gain of the amplifiers. —
Gain Set Point The value of the gain that the amplifier must
achieve. Automatic Power Control (APC) can
modify this value based on the number of optical
channel network connection (OCHNC) circuits that
are managed by the amplifier or to compensate for
fiber aging insertion loss. See the “18.4 Automatic
Power Control” section on page 18-18 for more
information.
Display only or numeric depending on mode setting.
When the system is configured as metro core, this field
is display only. When the system is configured as
metro access, this field can be changed by the user.
Tilt Reference (Display only) Shows the default value for the
amplifier tilt. This field can only be modified by
ANS.
—
Tilt
Calibration
Allows you to manually change the amplifier tilt. Numeric. Double-click the parameter, enter a value,
and press Enter.
Mode (Display only) Shows the working mode of the
amplifier.
• Control gain
• Control power
DCU Insertion
Loss
(OPT-PRE cards only; display only) Shows the
working mode of the amplifier.
• Control gain
• Control power
