    Conclusions

    In this paper, the influence of SRS crosstalk on the Super-PON system is investigated by simulation in which two cases are considered. The one case is using C-band for US and L-band for DS, and the other case is using C-band for DS and L-band for US. The simulation results show that when using C-band for DS and L-band for US, the power impairment of signals is the smallest, which is 0.43 dB (the single wavelength input optical powers of US and DS are 10 dBm and 13 dBm, respectively). Therefore, this combination mode is the best band-allocation scheme for the Super-PON system. Besides, we simulate the power impairment of signals caused by SRS when the Super-PON US and DS coexist with EPON US and 10G-EPON DS systems, and the results show that the SRS effect has little influence on them which can be basically ignored.
