Claim:
1. A method for authentication in a passive optical network (PON) comprising an optical line terminal (OLT) and an optical network unit (ONU), the method comprising: receiving, by the OLT, a first terminal serial number and a logic registration code of the ONU; determining, by the OLT, whether the first terminal serial number matches with a second terminal serial number stored on the OLT; determining, by the OLT, when the first terminal serial number does not match the second terminal serial number, whether the first logic registration code received from the ONU matches a second logic registration code stored on the OLT; and determining, by the OLT, that the ONU is a valid ONU and assign a formal ONU identifier (ONU-ID) to the ONU, if the first logic registration code matches the second logic registration code.
