Abstract—This paper contains an analyzing investigation of 32 channel - 10 Gbps DWDM-PON FTTH Simulate reaching a village in suburban area in environment that cannot put any sub node (amplifier or repeater) in the middle of the distance, therefore we design a system that deliver the CO signal directly from the OLT in the central of the city to the houses of the village all the way passive. to accomplish that we need a constant channel Spacing equal 100 GHz. with different dispersion (2,4,6,8,10 ps/nm.km) and power (-10, -5, -3,0,3,5,10) at the end of comparison of BER and Q factor for DWDM systems we reach a maximum distance 129 km with Q factor = 6.16 and BER = 3.44 e-10 in the presence of nonlinearities. This system can be severely limited by dispersion as we know smaller the dispersion the better the Q- factor but we will prove, not always the smaller the dispersion the better the Q-factor as we will see in some distance like 60,80 km the best performance is done with dispersion equal to 4, 6 and sometime 8 ns/nm.km not 2.
