This thesis investigates the integration of OOFDM with RoF for achieving high data rates and the transmission of the signal over long haul optical fiber. Therefore, the combination of OOFDM and RoF will enhance the system flexibility and help to cover a very large area without increasing the system complexity and cost very much. The OFDM-RoF design uses 128 subcarriers, 40 Gbps bitrates, 0.2 dB/km attenuation, 16.75 ps/nm dispersion, and 193,1 THz Laser frequency. OOFDM is an effective method to overcome different restrictions of optical fiber transmission systems such as chromatic dispersion, polarization mode dispersion, and modal dispersion. In this research, the model design for OFDM-RoF system uses single-port dual polarization method with QPSK and QAM modulation using OptiSystem software. Optical Orthogonal Frequency Division Multiplexing (OOFDM) technology commits to be a fundamental technique for accomplishing high data when is integrated with RoF. In WDM, multiple optical carrier signals are multiplexed and transmitted over one optical fiber. To increase the capacity and bandwidth of the optical fiber communication system a Wavelength-Division Multiplexing (WDM) is used. The demand for high-speed wireless communications is increasing rapidly. In RoF, light is modulated by using a radio signal and sent over an optical fiber link to simplify wireless access.
One of the advanced technologies in optical fiber communication systems that support efficient convergence of wireless and optical access network structure is Radio over Fiber (RoF).
