Description
Values
Default
Enable Laser
Enable
Enables or disables amplifier operation, i.e.,
turns the laser on or off.
ON (1) = Enabled
OFF (0) = Disabled
ON (1)
Laser Mode
LasMode
Selects one of two laser operating modes:
constant current (i.e., constant wavelength)
or constant power.
Constant Current
(ConstCur)
Constant Power
(ConstPwr)
ConstPwr
AGC Mode
AGC
Turns automatic gain control on or off.
ON (1)
Off (0)
OFF (0)
RF Drive Setting
RFDrive
Sets the relative RF drive level into the
transmitter. Only effective when AGC is off
(manual gain control).
-6.0 dB to +1.0 dB in
0.5 dB
steps
(Negative decreases
drive, positive
increases drive)
0.0 dB
OMI Level Setting
OMISet
Sets the optical modulation index level. Only
effective when AGC is on.
Note:
When AGC is active, it maintains a
constant OMI for input powers between
-3
dB and +1 dB from nominal when OMI level
is set to 0 dB.
In general, guaranteed AGC range is (
-3 +
OMI Level) dB to +1 dB. For example, for an
OMI level setting of +1 dB, the guaranteed
AGC range is 2 dB to +1 dB. Actual AGC
range is typically larger.
