Abstract :
|
Signal to Noise Ratio (SNR) has been investigated for radio over fiber systems based on optical single side band including the effects of chromatic dispersion, phase noise due to laser and oscillators discussed in this paper. Optical Single sideband signal is studied as it has tolerance for power degradation due to dispersion effects over a length of fiber. Investigations have been made out for Radio frequency of 30 GHz, with a laser source of 1550 nm. SNR has been evaluated using Power Spectral Density(PSD) function.SNR is studied for varying electrical receive required filter power to total RF power ratio over 10 Km fiber with chromatic dispersion D=17 ps/Km nm.
