Abstract: PURPOSE: A method for filtering an abnormal ONT with same serial number in a GPON system is provided to authenticate the registration of a subscribed optical subscriber device and block out the registration of the non-subscribed optical subscriber device. CONSTITUTION: An ONT(Optical Network Terminal)(20) performs the encoding and decoding of a PLOAM(Physical Layer OAM) of a registered-related frame based on an allocated open key according to optical network subscription. An OLT(Optical Line Terminal)(10) performs the decoding or encoding of the PLOAM of the frame from the keys allocated from the outside or the optical subscription device through the created key. According to the encoding and the decoding results, the optical circuit terminal process registration authentication of the optical subscriber device.
