Abstract:
1. A method for managing network components in a passive optical network (PON), comprising: transmitting, at a first wavelength, a first configuration message on the PON; receiving at a receiver a configuration response message from each of one or more optical network units (ONUs) in a first set of ONUs; based on the configuration response messages from the first set of ONUs, associating, in a database, each ONU in the first set of ONUs with the first wavelength; after transmitting the first configuration message, transmitting, at a second wavelength, a second configuration message on the PON; during transmission of the first configuration message, transmitting a configuration message comprising no bandwidth allocation for upstream transmission at the second wavelength; receiving at the receiver a configuration response message from each of one or more ONUs in a second set of ONUs, wherein the ONUs in the second set of ONUs do not belong to the first set of ONUs; based on the configuration response messages from the second set of ONUs, associating, in the database, each ONU in the second set of ONUs with the second wavelength; and using the database:
