Chapter 5 SNMP MIB Configuration
5.4.14 PumpCfgEntry
Note The values in mW and microW units are measured values. The dBm units are converted from mW or
microW to dBm, so theses values could be slightly different. If you take the
cerent15216EdfaInPoweruW, convert it to dBm (10log(cerent15216EdfaInPoweruW)) and compare the
value to the attribute cerent15216EdfaInPowerdBm, you will see a small difference. The difference is
because of rounding error. The value cerent15216EdfaInPoweruW that is displayed on the screen has
been rounded, but the value used in the calculation has more significant digits.
5.4.14 PumpCfgEntry
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 5-21
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.
cerent15216EdfaConstGainOver
allGainMeasured
Integer
(0 to 230)
Read-only The measured overall gain that is
used when the control mode in the
PumpCfg table is set to
constGainTempComp, in units of
0.1 dB. For example, a value of 219
is actually 21.9 dB.
cerent15216EdfaVariableGainPr
eAttenuationMeasured
Integer
(0 to 110)
Read-only The measured pre-attenuation that
is used when the control mode in the
PumpCfg table is not set to
constGainTempComp, in units of
0.1 dB. For example, a value of 10
is actually 1.0 dB.
