Problems solved by technology

[0003] At present, the automatic test of the PON system is still in the stage where the OLT controls the ONU to transmit test data. The passive transmission method of the ONU cannot meet its own needs, which is not conducive to the real-time monitoring, maintenance and management of the PON network status.

[0082] In this embodiment, the ONU sends the test data that needs to be transmitted to the OLT in the PLOAM message. When the ONU carries the test data that needs to be transmitted through the PLOAM message, it also carries a predetermined identifier in the PLOAM message to indicate the active transmission event or Indicates the transmission of test data, and the OLT and the ONU agree on the value of the specific field identifier in the PLOAM message, for example, the value of the second byte numbered 2 of the PLOAM message is set to 00001010. Correspondingly, when receiving the uplink data sent by the ONU, the OLT receives the test data transmitted by the ONU according to the predetermined identification.

[0115] In this embodiment, the ONU sends the test data that needs to be transmitted to the OLT through the OMCI channel. When the ONU sends the test data that needs to be transmitted through the OMCI channel, it also carries a predetermined identifier in the OMCI message to indicate the active transmission event. The OLT and The ONU agrees on the value of the transaction-related identifier in the OMCI message, for example, it can be set to 0x0000. Correspondingly, when receiving the uplink data sent by the ONU, the OLT receives the test data transmitted by the ONU according to the predetermined identifier.

[0142] In this embodiment, the ONU sends the test data that needs to be transmitted to the OLT through the OMCI channel. When the ONU sends the test data that needs to be transmitted through the OMCI channel, it also carries a predetermined identifier in the OMCI message to indicate the active transmission event. The OLT and The ONU agrees on the value of the transaction-related identifier in the OMCI message, for example, it can be set to 0x0000. Correspondingly, when receiving the uplink data sent by the ONU, the OLT receives the test data transmitted by the ONU according to the predetermined identification. If the ONU finds that the allocated bandwidth on the OMCI channel is not enough, the OMCI can request bandwidth from the OLT to transmit the test data that the ONU needs to transmit. The OLT can also predict whether the OMCI bandwidth needs to be allocated to the ONU according to the existing monitoring results of the ONU at the local end to transmit the test data that t...

Abstract

The invention discloses a method for transmitting test data, which comprise the steps: an ONU judges whether the self current situation meets a preset condition; and if so, the ONU transmits ONU test data to an OLT. The invention also provides a method for obtaining the test data, an ONU, an OLT and a PON system. The method obtaining the test data, the ONU, the OLT and the PON system provided by the invention lead the ONU to transmit the self test data in real time and also the OLT to obtain the ONU test data in real time, thus being helpful to the real-time monitoring on PON state.

Description

technical field [0001] The invention relates to passive optical network (PON) technology, more specifically, to a method for transmitting test data, an optical line terminal, an optical network unit and a passive optical network system. Background technique [0002] PON technology is a point-to-multipoint optical fiber access technology. figure 1 is a schematic diagram of the structure of the PON system, such as figure 1 As shown, the PON system includes an Optical Line Terminal (Optical Line Terminal, OLT), more than one Optical Network Unit (Optical Network Unit, ONU), and an Optical Distribution Network (Optical Distribution Network, ODN) that connects the ONU to the OLT. It is called a passive optical network node. Among them, the ODN includes a passive optical splitter (splitter) for optical power distribution, a trunk fiber connected between the passive optical splitter and the OLT, and a splitter connected between the passive optical splitter and the ONU. Branch fi...
