Testing Optical Port Specifications of Smart Line Boards

Testing Optical Port Specifications of Smart Line Boards

This section describes how to test the average transmit optical power and the actual receive optical power of smart line boards.

Testing the Mean Launched Optical Power of a Smart Line Board

If the mean launched optical power of an optical port is excessively high or low, bit errors occur, services are affected, and even equipment components are damaged. This section describes how to test the mean launched optical power of optical port on a smart line board, to verify that the mean launched power is normal.

Prerequisites

  • Fibers are correctly connected.
  • The laser of the optical port on the smart line board is enabled.

    NOTE:

    To enable the laser of an optical port on a smart line board, choose the smart line board in NE Explorer. Choose Configuration > WDM Interface from Function Tree. Select ByBoard/Port(Channel) in the right window. On the Basic Attributes tab, select the optical port and set Laser Status to On.

  • Performance monitoring has been enabled for NEs. For details, see Enabling Performance Monitoring for an NE.

U2000

Procedure

  1. Select an NE on the Main Topology view. Right-click the NE and choose NE Explorer from the shortcut menu.
  2. In NE Explorer, select the smart line board.
  3. Choose Performance > Current Performance from Function Tree.
  4. In the right pane, set Monitor Period to 15-Minute or 24-Hour. Click Measure and select Transmitted Optical Power in the Performance Event Type area. For details, see Enabling Performance Monitoring for an NE.



  5. Click Query to view mean launched optical power of the N1HUNS3 board.
  6. Check whether the mean launched optical power is normal by referring to Technical Specifications of HUNS3 or Technical Specifications of HUND2 in the Hardware Description.
  7. If the mean launched optical power is not within the specified value range, check and clean the fiber connectors connecting the NEs. For details, see Checking the Optical Fiber ConnectorEnabling NE Performance Monitoring and Cleaning the Optical Fiber Connector in the Supporting Tasks. Then repeat 5.

Testing the Received Optical Power of a Smart Line Board

If the received optical power of an optical port is excessively high or low, bit errors occur, services are affected, and even equipment components are damaged. This section describes how to test the received optical power of optical interfaces on a smart line board, to verify that the received optical power is normal.

Procedure

  1. Select an NE on the Main Topology view. Right-click the NE and choose NE Explorer from the shortcut menu.
  2. In NE Explorer, select the smart line board N1HUNS3.
  3. Choose Performance > Current Performance from Function Tree.
  4. In the right pane, set Monitor Period to 15-Minute or 24-Hour. Click Measure and select Received Optical Power in the Performance Event Type area. For details, see Enabling Performance Monitoring for an NE.



  5. Click Query to view received optical power of the N1HUNS3 board.
  6. Check whether the received optical power is normal by referring to Technical Specifications of HUNS3 or Technical Specifications of HUND2 in the Hardware Description.

    NOTE:

    The received optical power must follow the rule: minimum sensitivity + 3 dB ≤ received optical power (tested) ≤ minimum overload threshold - 5 dB.

  7. If the received optical power is abnormal, complete the following steps:

    • If the received optical power is excessively low, check whether fiber connectors, ODF-side flange plates, and optical attenuators are normal. Or replace optical attenuators. To clean fiber connectors, see Checking the Optical Fiber Connector and Cleaning the Optical Fiber Connector in the Supporting Tasks.
    • If the received optical power is excessively high, check whether optical attenuators are normal or add attenuators on the ODF side. For specific values of attenuators, see the note in 6.

  8. Repeat 5 to 7.
