Setup Commands
When setting a laser in constant current mode, the GAIN alarm is automatically disabled. The output
power alarm continues to function, testing for a 2 dB deviation of output power from the last output
power setpoint.
If necessary, the ALMDSBL command (see the“ALMDSBL” section on page 5-12) can be used to
disable the LPOUT alarm.
Note A value of zero will place the specified laser in idle mode.

Use Table 5-10 to interpret the SETI commands.
SETOUT
Explanation:
Constant EDFA output power mode has a configuration of 75 mW constant pump power for the
first-stage pump laser and the second-stage laser controlling the overall EDFA output power. Use the
SETOUT command to set the control point for the second-stage laser. The LPOUT alarm is
automatically enabled and the GAIN alarm is automatically disabled when the SETOUT command is
successfully issued.
A value of zero for the EDFA output power setpoint puts both pumps into IDLE mode. In this case, no
control mode line is displayed after you enter the SETOUT command.
