In this paper, we analyzed Cross Phase Modulation (XPM) crosstalk in bidirectional Passive Optical Networks. The proposed network is designed for Mixed Line Rates (MLRs) i.e. 10/ 20/ 40 Gbps to meet the requirement of high volume of heterogenic traffic. Further, the investigation is focused on uniform channel spacing and mixed channel spacing for MLRs. Various multidimensional results are presented to highlight and evaluate the impact of XPM in term of carrier to noise ratio (CNR), input power, received output power and BER. It is depicted that mixed channel spacing for MLRs performs better than conventional uniform channel spacing. It is also investigated that the effect of XPM on the system performance can be minimized with an optimal launch power..
