Abstract

A method and apparatus for authentication in a passive optical network are disclosed. In the disclosure, a first terminal serial number of an ONU and a first logic registration code are transmitted from the ONU to an OLT; if the OLT determines that the first terminal serial number does not match a second terminal serial number stored on the OLT, the OLT judges whether the first logic registration code received from the ONU matches a second logic registration code stored on the OLT; the OLT stores the first terminal serial number received from the ONU on the OLT if the first logic registration code matches the second logic registration code.

Claims

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 of the ONU;

determining, by the OLT, whether the first terminal serial number matches with the second terminal serial number stored on the OLT;

determining, by the OLT, that the ONU is a valid ONU and assign a formal ONU identifier (ONU-ID) to the ONU, in the event that the first terminal serial number match the second terminal serial number.
