The amazing growth in the usage of the broadband services has motivated a number of the services' providers to find drastic solutions. The percentage of broadband subscribers has increased from 5.3% of the world population in 2007 to 8.5% of the population in 2011. The increase in the number of subcarriers and a high bandwidth requirement are two motivations to demonstrate the broadband service provision. As a promised demonstration of the broadband provision, professionals use optical fiber to account for the present and the future broadband demand.
Power consumption and bandwidth capacity, which the optical fiber has offered, are two main requirements for success of any communication system. In this thesis several implementations have been added to such Passive Optical Network (PON) systems in order to meet the future broadband demand by maintaining the Bit Error Rate (BER). The interaction between Radio Frequency (RF) and optical fiber can support both wired and wireless communication systems. The modulation of RF signals has been tried by using different types in order to study the BER performance when PON is used. Three different optical millimeter signals were analyzed, which are Single Side-Band (SSB), Double Side-Band (DSB), and Optical Carrier Suppression (OCS) and applied to Wavelength Division Multiplexing- Passive Optical Network (WDM-PON) systems. The Orthogonal Frequency Division Multiplexing (OFDM) multi-carrier has been realized as an advanced modulation format of RF. Two different modulations methods of OFDM were used and compared at diffrenet levels
