1. A method comprising:
- initiating an activation procedure for a network terminal responsive to receiving a wavelength configuration message, the wavelength configuration message comprising one set of acceptable wavelengths assigned to the network terminal from among a plurality of sub-bands of wavelengths assigned to a plurality of network terminals;
identifying an instruction in the wavelength configuration message to modify a present wavelength used by the network terminal to a different wavelength within the set of acceptable wavelengths indicated in the wavelength configuration message,receiving at the network terminal an optical network unit identifier (ONU-ID) assignment;
identifying a present signal quality transmitted from the network terminal based on a signal transmitted from a transmitter of the network terminal;
determining the current wavelength utilized by the network terminal is incorrect based on the signal quality of the signal transmitted from the transmitter of the network terminal;
modifying the present wavelength to the different wavelength; and
transmitting subsequent data messages from the network terminal at the different wavelength.

Abstract
Tuning an optical network unit (ONU) to an appropriate communication wavelength may be performed by initiating an activation procedure responsive to receiving a wavelength configuration message, and identifying an instruction in the wavelength configuration message to modify a present wavelength used by the network unit to a different wavelength. The process may also provide assigning an optical network unit identifier (ONU-ID) to the network unit, modifying the present wavelength to the different wavelength, and transmitting subsequent data messages from the network unit at the different wavelength.
