Abstract
A method for detecting an optical network unit (ONU) in a passive optical network (PON), an ONU, a PON and an optical line terminal (OLT) are disclosed. In an embodiment the method include detecting an ONU identity code in an open uplink empty window or an empty timeslot, wherein the ONU identity code is a specific code stream sequence of the ONU that identifies a single ONU of the plurality of ONUs included in the PON system during the open uplink empty window or the empty timeslot and determining that the single ONU corresponding to the ONU identity code is a rogue ONU according to the ONU identity code.
Claims8
A method for detecting an optical network unit (ONU) in a passive optical network (PON) system including an optical line terminal (OLT) and a plurality of ONUs that communicate with the OLT via a shared optical transmission path, the method comprising:
- detecting an ONU identity code in an open uplink empty window or an empty timeslot, wherein the ONU identity code is a specific code stream sequence of the ONU that identifies a single ONU of the plurality of ONUs included in the PON system during the open uplink empty window or the empty timeslot;
- and
- determining that the single ONU corresponding to the ONU identity code is a rogue ONU according to the ONU identity code.
An optical line terminal (OLT) configured to detect an optical network unit (ONU) identity code in an open uplink empty window or an empty timeslot, wherein the ONU identity code is a specific code stream sequence of the ONU that identifies a single ONU of the plurality of ONUs during the open uplink empty window or the empty timeslot;
- and determine that the single ONU corresponding to the ONU identity code is a rogue ONU according to the ONU identity code.
An optical network unit (ONU), wherein the ONU is configured to send an ONU identity code to an optical line terminal (OLT), and wherein the ONU identity code is a specific code stream sequence of the ONU that identifies a single ONU.
A passive optical network (PON) system comprising:
- an optical line terminal (OLT);
- and
- at least one optical network unit (ONU), wherein the ONU is configured to obtain an ONU identity code and to send the ONU identity code,
- wherein the ONU identity code is a specific code stream sequence of the ONU that identifies a single ONU of the plurality of ONUs included in the PON system during an open uplink empty window or an empty timeslot, and
- wherein the OLT is configured to:
- receive the ONU identity code in the open uplink empty window or the empty timeslot;
- detect an ONU identity code;
- and
- determine that the single ONU corresponding to the ONU identity code is a rogue ONU according to the ONU identity code.
