An optical line terminal (OLT) comprises a processor configured to designate an extended quiet window having a start time and a stop time. The processor may be further configured to suspend upstream transmission during the extended quiet window. The OLT further comprises a transmitter that transmits a serial number (SN) grant to an optical network unit (ONU) during the extended quiet window. Upon receiving the SN grant, the ONU may transmit a plurality of calibration request messages during the extended quiet window. Each of the calibration request messages correspond to a different attempt wavelength. The OLT may receive one of the calibration request messages at a successful attempt wavelength. The OLT transmits a calibration response message identifying the successful attempt wavelength.
