 Radio-over-fiber (RoF) systems have been widely investigated due to such advantages of optical fiber as low loss, large bandwidth, and transparent characteristics for radio signal transmission. By utilizing RoF systems, various radio frequency (RF) signals including cellular services and wireless local area network (WLAN) signals can be efficiently distributed to densely populated areas or outdoor ranges. This paper investigates RoF transport systems that have the potential to offer large transmission capacity, significant mobility and flexibility, as well as economic advantage due to its broad bandwidth and low attenuation characteristics. The high performance of RoF communication systems are investigated against traditional optical communication systems using different coding formats over wide range of the affecting operating parameters. Moreover we have analyzed the transmission bit rates and products per channel based standard single mode fiber made of both silica-doped and plastic materials with using modified Shannon technique in addition to use different coding format such as non-return-to-zero (NRZ) code for ultra long haul transmission applications. We have taken into account the bit error rate (BER) for RoF systems with comparing it with traditional optical fiber communication systems as a proof for improvement of signal to noise ratio.
