Abstract
A method and system for upgrading service to an optical network terminal among a plurality of optical network terminals on a passive optical network. The upgrade enables bidirectional communications between a central office and the optical network terminal over dedicated downstream and upstream wavelength channels outside the downstream and upstream wavelength bands associated with the passive optical network. The optical network terminal to receive upgraded service is disconnected from a passive optical splitter at a remote node serving the optical network terminal, and optically coupled to a port of the multi-port arrayed waveguide grating at the remote node. Wavelength taps are provided at the central office and the remote node to facilitate multiplexing and demultiplexing the dedicated downstream and upstream channels with the downstream and upstream wavelength bands associated with the passive optical network. In this manner, certain users on the passive optical network may receive service upgrades to wavelength specific services without affecting other users who remain on the passive optical network.
