Method used to check whether the transmit optical power of a TOG board is fixed

34

You can query for a change in the transmit optical power of the TOG board on the NMS and determine whether the transmit optical power is fixed based on the query results.

Method used to handle low transmit optical power
Possible cause 1: Any fiber pigtail in a multiplexing part or the optical cable degrades or is physically damaged. As a result, the attenuation of the fiber increases, and the receive optical power decline causes an OSNR decrease. Possible cause 2: The OA board gain at the local or peer site is decreased. For possible cause 1: a. Check the pigtail of the multiplexing part, and replace the pigtail if it is abnormal. b. Verify that the optical cable is normal. Note: A pigtail in a multiplexing part is one between the following units: Equipment and ODF OA and FIU OA and MUX/DEMUX ODFs TDC and RDC of an OAU board For possible cause 2: Check the OA board gain. If the gain is abnormal, replace the board.

How to determine whether an optical module is identified by the switch or check the transmit power of an optical module
Run the display transceiver command on a switch. If the following information is displayed, the optical module can be identified by the switch. This command can also display the type, wavelength, transmission distance, and power of the optical module. NOTICE: The switch must have Huawei certified optical modules installed. Non-Huawei-certified optical modules cannot ensure transmission reliability and may affect service stability on the switch. Huawei is not responsible for any problem caused by non-Huawei-certified optical modules and will not fix such problems.
