How to read Optical Module information on Huawei Switches

      Optical modules are commonly used in switches, network cards, routers and other communications equipment, in the process of using the optical module information can be read to understand its real-time operating status, when there is a link abnormality can be more quickly locate the cause of the failure.
      Next, let's use Motek SFP-10G-LR module to access Huawei S6700 switch to introduce how to read the information of the accessed optical module on Huawei switch.

Figure 1 Schematic diagram of the optical module accessing the switch

1. Status of the Optical Module
      Execute the command "display interface interface-type interface-number" to view the interface information;
      The information output under this command contains the interface rate, module type, module link state (state UP is a prerequisite for the work of the optical module), and some statistical information, which can be used for troubleshooting.
      Explanation: interface-type interface-number is the interface type and interface number where the module is located, you can execute the command "display interface brief" to check the interface type and then determine the interface number according to the switch panel; if you don't know the interface type and interface number, you can use the command "display interface brief" to check the interface type and then determine the interface number. If you do not know the interface type and number, you can not enter them, and the information of all interfaces will be output at this time.

2. Switch identification of module and DDM detection data
      Execute the command "display transceiver interface interface-type interface-number verbose" to view the information of the optical module on the device interface;
      The information output under this command can be divided into two items, one is the identification information of the optical module, including the module type, wavelength, transmission distance, serial number, vendor name, etc., which originates from the coded data written by the optical module; the other is the DDM data of the optical module, including the real-time data diagnosis and the threshold range, which can be used to check whether the working status of the optical module on the two devices is normal or not by paying attention to the received optical power, transmitted optical power, temperature value and current value, etc. The DDM data of the optical module can be used to check whether the working status of the optical module is normal or not. module working status is normal.
