Monitoring the Link Between ONU and OLT

Monitoring the Link Between ONU and OLT

Link faults are common on GPON networks. You are advised to view the status of each monitoring point in advance and make preventive measures.

Context

Monitoring of eSight on the link between the ONU and OLT includes the following aspects:

  • Optical fiber status between the ONU and OLT
  • Link quality parameters: number of LOFI alarms, number of upstream FEC decoding uncorrected blocks, number of BIP error frames, and bit error rate
  • Status of the optical module on the ONU: working environment (voltage, current, and temperature) and power

Procedure

  1. Monitor the optical fiber status between the ONU and OLT.

    1. Choose Resource > PON from the main menu.
    2. Choose PON Resource > Equipment from the navigation tree on the left.

    3. Click the name of an OLT. The NE management window of the OLT is displayed.
    4. Choose View > Device Panel from the navigation tree on the left.

    5. Click a GPON port on the device panel, and view the optical fiber status between the ONU and OLT.

  2. Monitor the link quality parameters: number of LOFI alarms, number of upstream FEC decoding uncorrected blocks, number of BIP error frames, and bit error rate. You can choose either of the following methods:

    • (Recommended) Enter the OLT's NE Manager to view the link quality parameters.
      1. Choose Resource > PON from the main menu.
      2. Choose PON Resource > Equipment from the navigation tree on the left.

      3. Click the name next to a specific OLT in the OLT list. The OLT's NE Manager is displayed.
    • Enter the ONU's NE Manager to view data of a single ONU.
      1. Choose Resource > PON from the main menu.
      2. Choose PON Resource > ONU from the navigation tree on the left.
      3. Click the name next to a specific ONU in the ONU list. The ONU's NE Manager is displayed.

  3. Monitor the status of the optical module on the ONU: working environment (voltage, current, and temperature) and power.

    Enter the ONU's NE Manager to view data of a single ONU.

    1. Choose Resource > PON from the main menu.
    2. Choose PON Resource > ONU from the navigation tree on the left.
    3. Click the name next to a specific ONU in the ONU list. The ONU's NE Manager is displayed.
