  • Publication number: 20180083964
    Abstract: A method for authenticating an optical network unit (ONU) and devices for an optical line terminal (OLT) and an optical network unit (ONU) where an ONU is not allowed to be migrated in an authorized manner to an OLT of another vendor for use and binds the ONU and a particular vendor. The method also includes, when an ONU goes online, obtaining, by the OLT, first vendor information of the ONU, where the first vendor information is vendor information of a vendor to which the ONU belongs; comparing, by the OLT, the first vendor information with second vendor information, where the second vendor information is vendor information of a vendor to which the OLT belongs; and if a comparison result indicates that the OLT and the ONU belong to different vendors, determining, by the OLT, that authentication on the ONU fails.

  • Patent number: 9859975
    Abstract: An apparatus and a method for detecting an uplink optical signal. The apparatus includes a memory and a processor, where the processor is configured to determine a remaining bandwidth in a target uplink frame as a test window, where the remaining bandwidth in the target uplink frame indicates an unallocated bandwidth in the target uplink frame, and detect an uplink optical signal in the determined test window. Therefore, a remaining bandwidth obtained after bandwidth allocation in a target uplink frame is used to detect an uplink optical signal, which can effectively use a resource without the need of independently opening a test window and using an extra resource to detect the uplink optical signal, thereby avoiding waste of a resource and improving test efficiency.
