How to determine whether an optical module is identified by the switch or check the transmit power of an optical module

4

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.

Can I view the optical module types of switch and the receiving and transmitting power of the optical modules
You can use commands to view the information. To view the type of an optical module inserted into an optical interface, run the display interface interface-type interface-number command. To view the receiving and transmitting power on all interfaces, run the display transceiver diagnosis interface command. To view the receiving and transmitting power on an interface, run the display transceiver diagnosis interface interface-type interface-number command. For example: The display transceiver diagnosis interface GigabitEthernet 0/0/1 command displays the following information: Port GigabitEthernet0/0/1 transceiver diagnostic information: Parameter Current Low Alarm High Alarm Type Value Threshold Threshold Status ------------- --------- --------- ---------- -------- TxPower(dBm) -4.83 -11.02 -2.00 normal RxPower(dBm) NA -18.01 -1.00 NA Current(mA) 6.38 2.00 14.00 normal Temp.(C) 44.00 -20.00 90.00 normal Voltage(V) 3.31 2.90 3.70 normal

Method of querying optical module information on an AR router
Run the display transceiver command on an AR router to query basic information of optical modules, including module type, production SN, and manufacturer. Run the display transceiver verbose command to query detailed information of optical modules, including receive and transmit power of optical modules.

How do I determine the optical modules and cables supported by a card or switch
For CE series switches: - To determine the optical modules and cables supported by a card of the CE12800 series switches, see the "Indicators and Ports" section of the card model under "Cards" in the CloudEngine 12800 Series Switches Hardware Description. - To determine the optical modules and cables supported by CE8800&CE7800&CE6800&CE5800 series switches, see the "Appearance and Structure" section of the specific chassis model under Chassis > Chassis Models in the CloudEngine 8800&7800&6800&5800 Series Switches Hardware Description.
