Summary:Methods, systems, and apparatus for overlaying a passive optical network on a legacy optical access network are disclosed. In one aspect a system includes a legacy optical access network in a copper loop plant. The legacy optical access network provides access to customer premises. The system also includes a gigabit passive optical network (GPON) that is overlaid on the legacy optical access network. A fiber is shared by the GPON and the legacy optical access network. The GPON can provide a plurality of channels on the shared fiber at wavelengths that are separate and independent of wavelengths of the legacy optical access network.
