Optical network terminal (ont) wavelength tuning and correpsonding calibration procedure

An apparatus comprising:

• a receiver;
• a processor configured to
• initiate an activation procedure responsive to a wavelength configuration message received via the receiver;
• identify an instruction in the wavelength configuration message to modify a present wavelength being used to a different wavelength;
• assign an optical network unit identifier (ONU-ID);
• modify the present wavelength to the different wavelength;
• and
• a transmitter configured to transmit subsequent data messages at the different wavelength.

A non-transitory computer readable storage medium configured to store instructions that when executed cause a processor to perform:

• initiating an activation procedure for a network terminal responsive to receiving a wavelength configuration message;
• identifying an instruction in the wavelength configuration message to modify a present wavelength used by the network terminal to a different wavelength;
• assigning an optical network unit identifier (ONU-ID) to the network terminal;
• modifying the present wavelength to the different wavelength;
• and
• transmitting subsequent data messages from the network terminal at the different wavelength.
