Step 2 Repeat Step 1 for pump 2.
Step 3 Set the pump mode of operation using cerent15216EdfaPumpCfgControlMode attribute.
a. Select pump 1 or 2.
b. Set the mode.
Example 5-6 shows how to set the ONS 15216 EDFA2 to Constant Pump Current mode and then set it
back to Constant Gain Temperature Compensated mode. (Setting pump 1 or 2 to Constant Gain
Temperature Compensated mode sets both pumps to that mode.)

5.4.14.2 Changing the Pump Control Value
To change the control value for Constant Gain Temperature Compensated mode, the user must set a new
value of cerent15216EdfaConstGainOverallGain.
Constant Output Power mode is only valid for pump 2. To change the control value for pump 2, the user
must set the new value of cerent15216EdfaPumpCfgConstOutPower for pump 2. When Constant Output
Power mode is set for pump 2, pump 1 is automatically set to Constant Pump Power mode with a value
that is internally calculated.
To change the control value for Constant Pump Current mode, the user must set new values of
cerent15216EdfaPumpCfgConstPumpCurrent for both pumps.
To change the control value for Constant Pump Power mode, the user must set new values of
cerent15216EdfaPumpCfgConstPumpPower for both pumps.
For example, to change the value for Constant Pump Current mode, use the following steps:
Step 1 Set the pump value using cerent15216EdfaPumpCfgConstPumpCurrent attribute.
a. Select pump 1.
b. Set the value.
Step 2 Repeat Step 1 for pump 2.
Step 3 If desired, set the pump mode of operation using cerent15216EdfaPumpCfgControlMode attribute.
a. Select pump 1 or 2.
