Abstract: PROBLEM TO BE SOLVED: To maintain high accuracy of time synchronization, regardless of asymmetry of transmission delay in a PON section, in a PON system where an uplink PTP packet is received by a master ONU, and time information is provided to the OLT side, and delivered to all other slave ONUs via the OLT.SOLUTION: A master ONU compares the time of the own device with the reference time of a PTP packet, and notifies the OLT of the time difference. The OLT adjusts the time of the own device by using the notified time difference, and synchronizes the times of the master ONU and slave ONU with the time of the own device by applying a synchronization system. The slave ONU generates a PTP packet based on the time information acquired from the OLT, and transmits the PTP packet thus generated to a subordinate PTP slave device. By using the time information indicated in the PTP packet acquired from the slave ONU, the PTP slave device adjusts the time of the own device or executes PTP basic sequence between the slave ONU and itself thus synchronizing the time.SELECTED DRAWING: Figure 3
