Abstract: Principal requirements and technology trends of advanced DSP for high-speed, real-time Orthogonal Frequency Division Multiple Access (OFDMA)-based PON are analyzed. Key benefits emerge from component integration, mass production and parallel activity in long-haul fiber systems. Future PON technologies are highly cost-efficient to remain attractive and practical. OFDM technology that is well-suited for future PON Systems. But it requires advanced Digital Signal Processing (DSP). Moreover, we provide an analysis of primary cost factors in a practical DSP-based OFDMA-PON implementation and survey the most recent achievements in this domain. Due to the combination of highly attractive advanced features and favorable related trends in long haul fiber transmission, OFDMA-PON can be regarded as a very promising solution for future PON-based access.
Keywords: OFDM, OOFDM, Passive Optical Network (PON).
