Claim:
1. A method, in an active optical network unit (ONU),of reconfiguring wavelength of the active ONU, the method comprising the steps of: receiving a reconfiguration message from an optical line terminal (OLT), the reconfiguration message including new receive wavelength and new transmit wavelength assigned for the active ONU; performing, based on the reconfiguration message, both of, discarding transmission convergence layer parameters related to a current wavelength channel and replacing original receive wavelength and original transmit wavelength of the active ONU with the new receive wavelength and the new transmit wavelength included in the reconfiguration message, and subsequently de-activating and re-activating the active ONU, such that a receiver and a transmitter of the re-activated ONU work on the new receive wavelength and the new transmit wavelength.
