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 Power

(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.
