Method and device for registration lighting for ONU (optical network unit) device

Abstract

The invention relates to a method and device for registration lighting for an ONU (optical network unit) device. The method is characterized by comprising the following steps of transmitting data frame based on MPCP (multi point control protocol) between PON (passive optical network) interfaces, corresponding to ONU devices, in PON chips of the ONU devices and an OLT (optical line terminal) device; directly outputting a corresponding drive signal after analyzing and judging the received data frame through the PON chips so as to adjust the states of panel lamps, corresponding to the ONU devices, on the OLT device; or outputting a corresponding lighting signal to a logic chip after judging the received data frame through the PON chips, and outputting the corresponding drive signal after analyzing and judging the lighting signal through the logic chip so as to adjust the states of the panel lamps. By adopting the method and device, the conditions of the ONU devices under the PON interfaces, including normal registration of the ONU devices, interaction between the PON interfaces and the ONU devices, no registration of the ONU devices under the PON interfaces or no registration signal from the PON interfaces, can be visually displayed, and the prompt response and accuracy in judgment can be realized.

Description

technical field [0001] The invention relates to the field of passive optical network communication, in particular to a method and device for registering and lighting an ONU device in an OLT device. Background technique [0002] In the application of PON (passive optical network) technology, OLT (optical line terminal) equipment is an important local end equipment. It is interconnected with the optical splitter at the user end; realizes functions such as control, management, and distance measurement of the ONU (Optical Network Unit) at the user end. Usually, the way of panel lighting is adopted, so that the central office equipment can know the registration status of the ONU device under each PON port, so as to know the working status of the PON port and the working status of the corresponding ONU device in time. [0003] However, at this stage, the ONU device registration under the PON port is simply processed by the hardware, and then the logic chip directly lights up or u...

AI Technical Summary

Problems solved by technology

[0010] 1. Whether the ONU under the PON port is registered is not judged by the PON chip, but only by the Rxloss signal on the optical module; therefore, sometimes the registration information of the ONU cannot be accurately judged, and the link detection function cannot be completed

[0011] 2. The PON chip operates the ONU, and the registration or deregistration cannot respond in time, and can only be judged by the Rxloss signal

[0012] 3. The ONU lighting function of the OLT device is single, and the judgment methods required by different optical modules or Rxloss are inconsistent, which does not have good portability
