Performance Analysis of Radio over Fiber Network for Indoor Telecommunication Application

Radio over Fiber (RoF) as part of optical fiber communication could be the solution to the increasing number of demands in the success of telecommunication data processing, especially indoor where the communication traffic is higher than outdoor. An RoF network system set up is proposed for indoor application implementing for Indonesia's optical fiber communication system, which provides important benefits for the overall telecommunication system. In this network set up, DPSK digital modulation is used to modulate data in the RF signal. MZM is added as an external modulator. Random binary data is generated using PRBSs with 1 GBits/s bit rate. Various variants of 1:2, 1:4, and 1:8 power splitters are analyzed to identify the best performance of the network system. Received power, Q-Factor and Bit Error Rate are the performance parameters to determine the performance of the proposed network system. The performance parameters standards that are used is based on general telecommunication system in Indonesia with the ideal value of Q-Factor at 6, maximum BER at 10–9 and Received Power $\geq-35\mathbf{dBm}$.
