Basic components: RF -> optical : CW source and a modulator. opical -> RF : Photodetector. OIP3 (output intercept point). Assumption in all math: output noise independent of input power. phase change with thermal conductivity: optical fibre is chosen over RF cable. Direct Modulation: Shot noise : -168 dBm , Thermal noise : -174 dBm. Laser relative intensity noise(RIN): We do not desire RIN peaks in the passband.
