Figure 2 Output Power as a Function of Pump Current, for 0 dBm and -20 dBm Input Powers
Pressing the knob a second time after pump current adjustment has been completed will allow adjustment of the
pump laser temperature in the 20 °C to 30 °C range. Temperature adjustment is typically not needed for the
operation of the EDFA100S and EDFA100P; generally speaking, optimal performance will result when the pump
temperature is kept at the factory default of 25 °C.
Pressing the control knob again (i.e., a third time) will exit the adjustment mode and revert back to the viewing
mode, locking in the selected parameters. This can also be achieved by allowing the display to time out at any point
in the process. The display will adjust in real time to the new current setting.
5.5. Turning the Fiber Amplifier Off

Standby Mode
– By adjusting the control knob fully counterclockwise, the pump current will adjust down
to the threshold current and then to standby mode.

Disable/Enable Mode - The amplifier output can be turned off by pressing and releasing the ENABLE
switch. The pump diode temperature will be maintained even when the amplifier is disabled.

Power Down - When completely powering down an enabled unit, first press and release the ENABLE
switch and then turn the POWER key switch counterclockwise, which will turn OFF the entire unit. Anytime
the unit is turned OFF and then turned back ON, the fiber amplifier will be disabled until the ENABLE switch
is pressed. The pump current setting is retained when the amplifier is powered OFF.
