Proposals for Cost-Effectively Upgrading Passive Optical Networks to a 25G Line Rate
01 January 2017
Bandwidth demands keep increasing, inspiring researchers to continue to find cost-effective ways to increase the line rate in PON systems. In this paper we present and discuss proposals to upgrade 10G PONs with a 25 Gbps line rate at low cost and with low power consumption. Our proposals are based on binary NRZ and Duobinary based transmission which gained a lot of attention as solutions for upgrading PON to a 25 Gbps line rate in recent research papers as well as the standardization body IEEE. IEEE started standardizing 100G-EPON beginning of 2016. We report the latest results of our study of duobinary detection showing that it is a cost-effective technical feasible solution for 25G PON. Also topics like forward error correction and power consumption are investigated in the context of 25G PON.
