Querying Optical Power of a Board

The optical power of a signal changes after it is transmitted. This change affects intensity and sensitivity of the signal. If the optical power is too high or too low, bit errors or damage to optical components may be caused, affecting the service. Querying the optical power of the specific board is a common method used during maintenance to determine whether the optical power has changed.

Prerequisites

  • The fibers must be connected and the lasers must be enabled.
  • The performance event monitoring function must be started.

Context

For the OTU boards, you can query the optical power of client interface.

Procedure

  1. In the NE Explorer, select a board and choose Configuration > Optical Power Management from the Function Tree.

  2. Click Query to get the current optical power value from the NE.
  3. Check the current optical power value and compare it with the reference value.

    NOTE:
    If there is a big difference, you must check the historical value to ensure that the optical power is normal.

  4. Optional: Record the current optical value and compare it with the historical value.
