ons15501OutputSignalPower

The optical signal power at the output of the Amplifier.
The value of this attribute triggers the alarm, based on
mean value and trigger as defined by 
ons15501OutputSignalPowerMean and
ons15501OutputSignalPowerTrigger.
          
This value is internally calculated using the following
formula.
 ons15501OutputSignalPower = ons15501OpticalPowerGain +
                                ons15501InputOpticalPower
At very low ons15501InputOpticalPower (below -16 dBm),
the ons15501OutputSignalPower has significant difference
from ons15501OutputOpticalPower while at higher input
power (ons15501InputOpticalPower) they are closer.
          
Following graph captures the difference (for a 17 dBm
EDFA)
   (dashes '-'/'_' denote optical output power
    while dots '.' denote signal output power)
