摘要
In this paper, a novel optical access network based on orthogonal frequency division multiplexing （OFDM） is proposed. An OFDMbased 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 OFDMPON with different linewidths of the lightwave source, different optical signaltonoise ratio （OSNR）, different access distances, and different modulated formats. Colorlessness in the OFDMPON is also analyzed. Finally, a 40 Gb/s baseband OFDM-PON with two carriers and achieve errorfree performance over 25 km fiber transmission is proposed.
