The wide range of applications on wireless platforms requires direct access to large amounts of wireless avenues that can be achieved in the orthogonal channel. Orthogonal Frequency Division Multiplexing (OFDM) is a modulation technique for transmission of communication through recent wireless and optical channel. The OFDM is a recent multiple access technology for both wired and wireless mediums. This research focuses on the OFDM modulation technique that can be adapted to the RoF system. The combination of OFDMRoF (Radio over Fiber) is found to satisfy various demands on the OFDM system. The main objective of this research work is to identify the minimum bit error rate and better QFactor for the QAM modulation. This work executes two cases based on QAM modulation namely 4 and 16-QAM modulations and each case has various data rates, subcarriers, and their different distances are compared with the BER and Q-Factor.
