ITU values are set at the factory and cannot be changed in the field.
Configurable Parameters
Parameter
Name (LCI) ICIM
Abbreviation Description Values Default
Laser Enable Enable Enables or disables amplifier
operation; that is, turns the laser on or
off.
ON (1) = Enabled
OFF (0) =
Disabled
ON (1)
Low RF Alarm
Inhibit
LoRFInh Enables or disables the "RF input low"
alarm.
ON (1) = Alarm
Enabled
OFF (0) = Alarm

OFF (0)
AGC Mode AGC Turns automatic gain control on or
off.
Inactive (0)
Active (1)
Inactive (0)
RF Drive
Setting
RFDrive Sets the relative RF drive level into
the transmitter. Only effective when
AGC is off (manual gain control). This
is used in conjunction with OMI set.
Values from -2 dB to +2 dB allow
OMI set to be adjusted and maintain
specified performance
-5 dB to +4 dB 0.0 dB
OMI Level
Setting
OMISet Sets the optical modulation index
level. Only effective when AGC is on.
NOTE: When the AGC control is in
the “on” state, the composite OMI can
be changed from the factory-preset
level. If the RF input power is 0dB
relative to nominal, the range is [-5,
+1] dB. If the RF input power is less
than 0 dB relative to nominal, the
maximum OMI set value is 4 dB + RF
Input Level.
-5dB to +1.0 dB
when RF drive
setting is 0 dB
0.0 dB
Length FibLinDi
Sets the nominal link distance for
optimum performance.
0 to 100 km in 10
km steps
50 km
Dither Dither Turns Dither on or off. Dither may
need to be turned off for high drive
levels or channel loads in order to
improve performance.
ON (1)
OFF (0)
OFF (0)
