Radio over fiber (RoF) systems is one of the technologies which carry microwave signals and distributed it using the optical fiber cable from the control station to the base station. The combining of wireless and optical networks is a potential solution for increasing capacity as well as decreasing costs in the network. The overall purpose of the project is to simulate the radio over fiber in point-topoint (PZP) network and compare the modulation performance of RF using Phase Shift Keying (PSK) and Differential Phase Shift Keying (DPSK). The performance of both mdulation techniques are compared through simulation by using Optsim provided by RSoft. The performances are characterized through Bit Error Rate (BER) for eye opening and input power. For PSK modulation technique, the transmission power is -16 dBm, with bit rate a t 1.25 Gbps and the frequency up to 1 GHz. It is found that the performance of PSK modulation is better than DPSK modulation technique in most of simulation results because it have a high sensitivity for detection and good tolerance to nonlinearity of transmission line.
