[0062] Such as figure 1 As shown, the detection method of the long-emitting optical network unit in the embodiment of the present invention includes:

[0063] Step 11: After detecting the optical network unit ONU failure alarm, assign a fixed time slot to each ONU connected in communication with the OLT, and record the correspondence between the ONU identifier of each ONU and the assigned time slot of the ONU relation.

[0064] In the embodiment of the present invention, the OLT can perform fault detection on the ONU according to a predetermined detection cycle, and after detecting an ONU fault alarm, a fixed time slot is assigned to each ONU connected to the corresponding PON port of the fault alarm ONU. The fault alarm here may specifically be an ONU upstream bit error alarm, a round-trip time delay RTT drift, or other preset alarm information.

[0065] Here, a fixed time slot can be assigned to each of the ONUs according to a preset allocation strategy, wherein the preset...

[0077] Such as figure 2 As shown, the detection method of the long-emitting optical network unit in the embodiment of the present invention includes:

[0078] Step 21: Record the online and offline information and ONU bit error information of each ONU according to the preset recording period.

[0079] In a specific embodiment of the present invention, the OLT central office device may record the online and offline information of the ONU and the error information of the online ONU in units of PON ports according to a preset recording period. Preferably, the online and offline information of the ONU and the error information of the ONU can be recorded according to the detection result of the long luminescent signal. Specifically, when no long luminescence signal is detected in the current recording period, the relevant ONU information in this period is included in the normal period information; when a long luminescence signal is detected, the relevant ONU information in this p...

Abstract

The invention provides a long-luminescence optical network unit (ONU) detection method, a detection device and an optical line terminal (OLT), so as to solve the problem of difficult long-luminescence ONU positioning caused by ONU uplink grant time slot dynamic changes. The method comprises steps: after ONU fault warning is detected, a time slot is fixedly distributed for each ONU in communication connection with the OLT, and the corresponding relationship between the ONU identifier of each ONU and the time slot distributed for the ONU is recorded; long-luminescence signal detection processing is carried out on the ONU, and a time slot range corresponding to ONU long-luminescence signals is acquired; according to the corresponding relationship between the ONU identifier and the time slot distributed for the ONU and the time slot range corresponding to ONU long-luminescence signals, a suspicious fault ONU set is determined; and a long-luminescence ONU is detetced in the suspicious fault ONU set. Through fixedly distributing the time slot for the ONU, the problem of difficult long-luminescence ONU positioning caused by ONU uplink grant time slot dynamic changes is solved.

Description

technical field [0001] The present invention relates to the technical field of communication applications, in particular to a detection method, device and optical line terminal of a long-emitting optical network unit. Background technique [0002] In the xPON network of the passive optical network, the common networking system generally consists of an element management system (Element Management System, EMS), an optical line terminal (optical line terminal, OLT), an optical distribution network (Optical Distribution Network, ODN) and several An Optical Network Unit (ONU), the OLT, as a central office device, aggregates multiple ONU devices through the ODN network connection, and the ONU device realizes the access of user services, thereby realizing functions such as data services and configuration management. The xPON network is a "point-to-multipoint" topology: the transmission direction from the OLT to the ONU is the downlink direction, and the downlink direction uses bro...
