US 2007/0166037 A1 · System and Method for Managing Network Components in a Hybrid Passive Optical Network

Abstract

In accordance with the teachings of the present invention, a system and method for managing network components in a passive optical network (PON) is provided. In a particular embodiment, the method includes transmitting, at a first wavelength, a first configuration message on the PON, wherein the first configuration message comprises a first transmitter interface number. The method also includes transmitting, at a second wavelength and at approximately the same time as the first message, a second configuration message on the PON, wherein the second configuration message comprises a second transmitter interface number. The method further includes receiving a configuration response message from each of one or more optical network units (ONUs) in a first set of ONUs that comprises the first transmitter interface number and receiving a configuration response message from each of one or more ONUs in a second set of ONUs that comprises the second transmitter interface number. The method also includes, based on the configuration response messages from the first set and second set of ONUs, associating, in a database, each ONU in the first set of ONUs with the first wavelength and each ONU in the second set of ONUs with the second wavelength. The method further includes, using the database, transmitting downstream traffic destined for any ONU in the first set of ONUs at the first wavelength and transmitting downstream traffic for any ONU in the second set of ONUs at the second wavelength.
