Abstract

We have studied transmission properties of the previously proposed passive optical network (PON) using hybrid Raman amplifiers for upgrading the existing PON. We focus on the upgrading of 10G-EPON (also XG-PON) system, which uses optical burst signals for upstream transmission. This paper discusses the transmission properties of the hybrid Raman amplifiers for burst signals. In access networks, there are many splice points and connection points. These points may reflect signal waves and may interfere with themselves, which is called a multipath interference (MPI). We also study degradation due to MPI in the hybrid Raman amplification. With the obtained results, we evaluate required reflection coefficients of splices in the previously proposed PON using hybrid Raman amplifiers.
