Radio over fiber is an integration of microwave and optical fiber technologies having numerous benefits. RoF technology can give a scope of advantages including the capacity for backing multiple radio services and standards. In order to maintain Signal Integrity in RoF system, it’s indispensable to take all components of a system under rooted consideration. Due to the increasing number of RoF application, it’s necessary to do some system level changes in designing RoF transceiver. In this paper we compared two popular modulation techniques NRZ (non return to zero) and RZ (return to zero) for better signal integrity in RoF system. Secondly we also did analysis of RoF transceiver with APD and PIN photo detectors and compared the performance on different distances. Hence the Q factor of PIN and APD photo diodes and comparison of NRZ and RZ modulation will be helpful for system designers who are working on better signal Integrity in Radio over fiber systems.
