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.
