ROF system of key performance indicators

ROF system key performance indicators are: noise factor link gain G, the system NF, spurious-free dynamic range SFDR, third order intermodulation distortion IMD3, third-order intercept point of IP3
. 1, the link gain G: link gain into optical gain and an RF gain
2, the noise figure NF: output noise power with input noise power ROF link $NF = 10lg ((sin / Nin) / (sout / nout)) = 10lg (nout / gtnin)$
. 3, spurious-free dynamic range SFDR:Baidu Encyclopedia
4, third order intermodulation distortion IMD3: the output power level of the signal power by subtracting the amount of third-order intermodulation value level
5, third-order intercept point IP3: signal frequency over the output signal of the third order intermodulation linear system when the intersection point is equal to the amplitude component, is a fixed point
