Performance of 10G-EPON

10G-EPON system specifications have reached the end of the development cycle, with the release of the final standard version. Recent announcements of first practical 10G-EPON demonstrations [1, 2] indicate rapid adoption of these specifications by system vendors. Given the growing interest in 10G-EPON, it is useful to examine the worst-case scenario performance of this new first-mile access network in both downstream and upstream channels. Due to the number of technical changes introduced to 10G-EPON when compared with 1G-EPON, the obtained performance figures are substantially different from those of its predecessor. The results presented in this article have been obtained through an analytical model and confirmed by detailed simulation.
