5.4.14.1 Changing the Pump Control Mode
For Constant Gain Temperature Compensated, Constant Pump Current, Constant Pump Power, or idle
modes, the system automatically sets the second pump to the same mode when either pump is set.
Constant Output Power mode is only valid for pump 2. If pump 2 is set to Constant Output Power Mode,
pump 1 is automatically set to Constant Pump Power mode with an internally calculated value.
Warning The pump control modes Constant Pump Current, Constant Pump Power, and Constant Output Power
are to be used with very high precautions. They are service affecting and can reduce the life cycle of
the lasers if used in extreme conditions. The factory default setting and recommended mode of
operation is Constant Gain Temperature Compensated mode. Cisco recommends that users contact
the Cisco TAC before changing from this mode of operation.
To set the ONS 15216 EDFA2 to 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.

idle(6)
Read-write Laser pump control mode. When the
mode is set directly to constCurrent,
constPower, or constOutputPower, the
respective current value of
ConstPumpCurrent,
ConstPumpPower, or ConstOutPower
is used as the constant parameter for
the new mode.
Note: Pump 1 cannot be set to
constOutputPower mode.
cerent15216EdfaPumpCfgC
onstPumpCurrent
Integer
(0 to 300)
Read-write Constant pump current (mA).
The current that is used when the
pump control mode is changed to
constCurrent.
cerent15216EdfaPumpCfgC
onstPumpPower
Integer
(0 to 100)
Read-write Constant pump power (mW). The
power that is used when the control
mode is changed to constPumpPower.
cerent15216EdfaPumpCfgC
onstOutPower
Integer
(0 to 650)
Read-write Constant output power. The power that
is used when the control mode is
changed to constOutputPower. In units
of 0.1 mW. For example, a value of
551 is actually 55.1 mW.
