5.4.2 PumpCfgEntry Table
The cerent15216EdfaPumpCfgEntry table is used to set or get laser pump control mode configuration.
The associated table command displays a settings summary or allows you to set pumps. See Table 5-7
for variable definitions. The factory default pump control mode for the ONS 15216 EDFA2 is Constant
Gain Temperature Compensated. Cisco recommends that users contact the Cisco TAC prior to changing
this mode of operation.
5.4.2.1 Changing the Pump Control Mode
For Constant Gain Temperature Compensated mode, the system automatically sets the second pump to
this 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 a value of 75 mW.
For Constant Pump Current or Constant Pump Power mode, the user should set both pump modes to be
the same.
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.
