Abstract :
The distortion characteristics of a radio-over-fiber (ROF) system that uses the relative intensity noise (RIN) reduction technique is investigated in detail. The third-order intermodulation (IM3) and spurious free dynamic range (SFDR) characteristics of this system are measured using multi-reflection configurations. It is observed that the maximum deterioration in IM3 is 4 dB. However, SFDR is improved by 7 dB as CNR exceeds 12 dB. Moreover, we measure the adjacent channel leakage power ratio (ACLR) characteristics of this system in the multi-carrier transmission condition. The RIN reduction technique yields an ACLR improvement of 4.5 dB
