METHOD OF IDENTIFYING LONG-SHINING ROGUE ONU IN PASSIVE OPTICAL NETWORK

摘要

The present invention discloses a method of identifying a long-shining log ONU in an OLT of a passive optical network, comprising the steps of: A. assigning a specific radio frequency signal of a different frequency to each of the ONUs of the passive optical network; And B. When a long-shining log ONU is detected in the passive optical network, b1. Broadcasting a control message to each of the ONUs; b2. Receiving uplink signals in an uplink; b3. Recovering specific radio frequency signals transmitted by normal ONUs from the uplink signals; And b4. Identifying a particular radio frequency signal of the member according to the recovered specific radio frequency signals, wherein the ONU corresponding to the particular radio frequency signal of the member is a long-shining log ONU. The present invention also discloses an OLT device that performs the method and a method in an ONU that helps the OLT to identify a long-shining log ONU.
