Why is Power Penalty important?

Power penalty, resulting from a nonideal Extinction Ratio (ER), is important in optical communication because it quantifies the impact of signal quality on data transmission. The Extinction Ratio represents the contrast between the optical signal's on and off states.

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 P_er symbol.

How to calculate Power Penalty using this online calculator? To use this online calculator for Power Penalty, enter Extinction Ratio (r_e) and hit the calculate button. Here is how the Power Penalty calculation can be explained with given input values -> 0.799118 = -10*log10((10.9-1)/(10.9+1)).

FAQ

What is 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 and is represented as P_er = -10*log10((r_e-1)/(r_e+1)) or Power Penalty = -10*log10((Extinction Ratio-1)/(Extinction Ratio+1)). Extinction Ratio represents the ratio of the average power in a logic 1 to the average power in a logic 0.
