In future, various optical access systems will be deployed depending on the required data transmission capacity. For smooth migration, generic network management scheme is desired. In this paper, generic remote ONU management scheme by adopting the virtualization of logical channel in various optical access systems is described.
We investigate ONU power leveling methods for mitigating Inter-channel crosstalk of upstream signals in TWDM-PON. 6-dB power dynamic range was archived with maximum 1.4-dB power penalty by adjusting operation current of Tx. The proposed method is thought to be a simple, low-cost solution in comparison with that with a VOA or SOA. Further study is needed for trade-off between crosstalk and eye distortion...
