Orthogonal frequency division multiple access PON (OFDMA PON) employs orthogonal frequency division multiplexing (OFDM) as the data modulation scheme to increase the provisioning data rate. Qian et al. [89] demonstrated the transmission of 108 Gb/s downstream data rate over a type B fiber with a split ratio of 32. Figure 6.1 describes one typical OFDMA PON architecture. OFDMA PON uses OFDMA as an access scheme [90, 111], which divides the upstream/downstream bandwidth in baseband into multiple subcarriers with orthogonal frequencies. These subcarriers are dynamically allocated to different ONUs based on their real-time incoming traffic information. As compared to TDM PON and WDM PON, OFDMA PON enjoys numerous advantages such as high speed transmission, fine granularity of bandwidth allocation, and color-free ONUs [137].
