|Title||Characterization of Radio over Fiber Employed GPON Architecture for Different Modulation Schemes|
One of the most significant developments within the fiber optic technology is passive optical network (PON) which is a point-to-multipoint network architecture. Compare to other PONs, Gigabit-PON (GPON) is attractive due to the flexibility, simple and low cost passive connection. Radio over fiber (RoF) is One of the most important applications in the fiber optic system, RoF is a hybrid system that integrates the wireless and optical in one system. The combination of GPON with RoF technology provides high capacity, high data rate and low cost of development. This research provides characterization of RoF employed GPON architecture for wireless distribution network. The Simulations has been performed on OPTISYSTEM software. The analysis of simulation results are based on the bit error rate (BER), received signal strength and eye pattern obtained for various modulation schemes. The system has been analyzed using phase shift keying (PSK) modulation, differential phase shift keying (DPSK) modulation and offset quadrature phase shift keying (OQPSK) modulation with different length from the optical line termination (OLT) to optical network unit (ONU). The best results were achieved using PSK modulation, and for different modulation schemes, the BER is accepted for length of fiber up to40 kmin upstream and downstream.
