Abstract

In this paper, we present an electrical dispersion compensator (EDC) for a 1.25 Gb/s gigabit passive optical network (GPON) with Fabry-Perot (FP) lasers. Due to mode-partition noise (MPN) from the FP laser and fiber dispersion, GPON systems suffer from inter-symbol interference (ISI). The choice of the architecture for the EDC is a feed-forward equalizer (FFE) structure. The GPON experimental link was set-up with 0~15km fiber with a commercial triplexer. The EDC successfully compensates ISI for a given link with a 1.25 Gb/s PRBS signal. The EDC is implemented in 0.18 um CMOS technology with 54 mW power consumption from a 1.8 V power supply.
