摘要： In this paper, a novel optical access network based on orthogonal frequency division multiplexing (OFDM) is proposed. An OFDM-based passive optical network (PON) uses multicarriers to carry different information that is transmitted to different optical network units (ONUs). In this paper, system performance is analyzed for OFDM-PON with different linewidths of the lightwave source, different optical signal-to-noise ratio (OSNR), different access distances, and different modulated formats. Colorlessness in the OFDM-PON is also analyzed. Finally, a 40 Gb/s baseband OFDM-PON with two carriers and achieve error-free performance over 25 km fiber transmission is proposed.
