This paper represents the orthogonal frequency division multiple access passive optical network (OFDMA-PON) as a promising solution for next level PON due to its high spectral efficiency and flexible bandwidth allocation scheme. Various techniques are used by different researchers for orthogonal frequency division multiple access. So far, an OFDMA-PON technique has been widely accepted. It shows that the various DBA schemes have been proposed to enhance the performance of the network. The overall objective of this research paper is to compare the different techniques based on OFDMA-PON and investigate the performance of various independent services.
