Abstract:
1. A method implemented at an optical line terminal (OLT) to support wavelength management for a passive optical network (PON) comprising: receiving, using a receiver, a wavelength and tunability report in a Serial_Number_optical network unit (ONU) physical layer operations, administration, and management (PLOAM) message, wherein the wavelength and tunability report is received from an ONU, wherein the wavelength and tunability report comprises data that indicates an ONU transmitter wavelength, an ONU receiver wavelength, an ONU transmitter tunability, and an ONU receiver tunability, and wherein the ONU transmitter tunability and the ONU receiver tunability each comprise a plurality of wavelengths; sending, using a transmitter, a wavelength assignment command to the ONU in a Assign_ONU-ID PLOAM message, wherein the wavelength assignment command indicates an assigned ONU transmitter wavelength and an assigned ONU receiver wavelength; exchanging a registration with the ONU; and exchanging a wavelength assignment change with the registered ONU in an operation phase subsequent to the registration.
