Abstract
A method, a computer readable medium, and a system for discovering an Optical Network Terminal (ONT) in a Dense Wave Division Multiplex (DWDM) hybrid Passive Optical Network (PON) Line Terminal (LT), comprises implementing, by an Optical Line Termination (OLT), a ranging procedure on at least one downstream link, wherein the OLT is communicably coupled to the ONT, discovering at least one new ONT, by the OLT, on the at least one downstream link based on the ranging procedure, discovering an unranged ONT, by the OLT, during the ranging procedure, and determining, by the OLT, that the unranged ONT resides on the at least one downstream link.
