How to Calculate Power Penalty?
Power Penalty calculator uses Power Penalty = -10*log10((Extinction Ratio-1)/(Extinction Ratio+1)) to calculate the Power Penalty, Power penalty is a measure of how much the received optical power deviates from the ideal power level due to various impairments in the system. In the context of nonideal ER, power penalty quantifies the additional power loss or distortion in the received signal caused by an insufficient extinction ratio. Power Penalty is denoted by Per symbol.
