The switch uses the fiber optic module to interconnect the light on one end or on both ends. How to deal with it? Next, let's follow the editor of Feichang Technology to learn more about it!
1. Use the corresponding interface of dis int to confirm that the module has been correctly identified;
2. Confirm whether the physical parameters of the optical modules at both ends are consistent, such as wavelength, speed, and distance (Note: Gigabit optical modules can only communicate with Gigabit, and 100M can only communicate with 100M);
3. Use the pigtail to loop back the optical module to confirm whether the optical module is normal (note: the loopback of the single-mode module needs to add optical attenuation to prevent the optical module from being burned by excessive optical power);
4. Force rate and duplex (speed 1000; duplex full) on the physical interface corresponding to this optical module;
5. After finishing the above operations, if there are still the above problems, you need to use an optical power meter to test the optical power of the optical module, and confirm whether the optical power is within the critical range of the received optical power of the module! (Please refer to the installation manual of each product for the optical power of the corresponding optical module).
Well, the above content is about how to deal with the fact that the light on one end or both ends of the fiber optic module interconnection of the switch is not bright, and how to deal with it? A detailed introduction to this issue, I hope it can be helpful to everyone!
