Abstract: Radio over Fiber (RoF) is one of the efficient technology in modern communication system by combination the facilities of optical communication capacity and the mobility of wireless networks. ROF technique provides many advantages in addition to the conventional wireless communication system such as high signal quality, low cost and high reliability. In this research, radio over fiber transmission for 100 km-long optical fiber operated at 1 Gb/sec data rate and modulated under efficient DPSK modulation technique is employed. The performance of the transmission system is evaluated using OptiSystem Version-10 in terms of max. Q-factor, min. bit error rate, eye height, threshold and decision inst. The performance of the system is improved by utilizing fiber bragg grating under dispersion compensation fiber scheme. According to our results, the set up utilizing DCF with FBG scheme has the better performance as compared to other schemes where Q factor, BER, eye height, threshold and decision inst. are 23.5971, 1.999*10-123 , 1.986*10-005 ,2.217*10 -005, 0.446, respectively.
