Abstract
A scheme to easily upgrade TDM-PON using WDM overlay is proposed. To maintain the colorless characteristics of ONU transmitters, a wavelength-conversion ONU is adopted for each TDM-PON group, where all upstream signals from regular ONUs are adjusted to an assigned wavelength. An implementation scheme for remote node and wavelength conversion node is suggested and the test results are shown.
