Abstract—Radio over fiber (ROF) has been developed since 20th century and has been used efficiently for the provision of untethered access to broadband wireless communications in a range of applications including last mile solutions, extension of existing radio coverage and capacity, and backhaul. RoF is the next generation communication systems that can utilize the high capacity of optical networks along with the mobility of wireless networks. Optical fiber has many advantages compared to conventional system with low attenuations and superior signal integrity found, it allow much longer intervals of signal transmission. It is not unusual for optical systems to go over 100 kilometers, emerging technologies promise even greater distances in the future. By incorporating OFDM along with RoF, the system can be used for both short distance as well as long-haul transmission at very high data rate. Large capacity RF signals as well as ultra-wide band wireless access is achieved. This paper investigates the performance and characteristics of Orthogonal Frequency Division Multiplexing (OFDM) as a modulation technique for a ROF. The project is about to modeling and simulates OFDM Radio Over Fiber scheme using latest commercial software called Optisystem. This is the pre-exquisite method that only uses standard components of optical telecommunications. As a result the model of this paper can be used with different wireless communication systems such as high data rate Wireless LANs, Fiber-To-Home (FTH), WiMax, and Digital Video Broadcasting (DVB) and it is supporting to the 4th generation cellular systems. The detail of the design in Optisystem and simulated results for the proposed model are shown and elaborate.
