OPTICAL LINE TERMINALOLT FOR MANAGING LINK STATUS OF OPTOCAL NETWORK UNITSONUs AND GIGABIT ETHERNET PASSIVE OPTICAL NETWORKGE-PON APPLING THE SAME

Gigabit Ethernet-based passive optical for managing the link state of the optical line network unit (ONU) of this invention access network is, data transfer bandwidth allocation requirements for the transmission of data signals to the next window period by using the assigned data transmission interval at least one ONU (optical Network Unit), one side of the connection with the ONU, respectively, and when the other is configured to at least one optical communication channel switch the input signal to the destination transmission signal transmits a report signal and a data signal containing the optical splitter, and on the assigned data transfer section verify the ONU transmits a whether or not to receive the report signal and the received report signal and confirm receipt of the data signal during the data transmission interval allocated by the ONU transmits a report signal to ONU that It has an OLT (Optical Line Terminal) for determining link status for the management. Oh enyu, OLT, the passive optical network based on Gigabit Ethernet, link status, identification, management
