How to read optical module information on H3C 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 us use Moduletek QSFP-40G-LR4 module to access the H3C S6820 switch, to introduce how to read the information of the accessed optical module on the Huasan switch.

Figure 1 Schematic diagram of optical module accessing the switch

1. Status of Optical Module
      Execute the command "show 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 type and number of the interface where the module is located, you can execute the command "show 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 number, you can not use the command "show interface brief". If you do not know the interface type and number, you can not enter them, and all the interface information will be output at this time.

2. Switch identification of module
      Execute the command "show transceiver interface interface-type interface-number " to view the information of the optical module on the interface of the device;
      The information output under this command is the identification information of the optical module, including module type, wavelength, transmission distance, vendor name, etc., which is derived from the coded data written by the optical module.

3. DDM Detection Data of Switch to Module
      Execute the command "show transceiver diagnosis interface interface-type interface-number" to view the information of the optical module on the device interface;
      The information output under this command is the DDM data of the optical module, including real-time data diagnosis and the threshold range. By focusing on the received optical power, transmitted optical power, temperature value, current value, etc., you can check whether the working status of the optical module on the equipment at both ends is normal.
