We have studied bidirectional lump Raman amplification (LRA) for upgrading the existing passive optical network (PON). We focus on the upgrading to TWDM-PON (or WDM/TDM-PON) systems economically. First of all, we investigate properties of a bidirectional LRA theoretically considering the co-use of 10 G-EPON and TWDM-PON. Then, we investigate them experimentally using a dispersion-shift fiber (DSF) and a high-nonlinear fiber (HNLF). Finally, we made fundamental bit error rate (BER) experiments to confirm the feasibility of the co-use method.
