Huawei switches using non-certified optical module may not be able to read the information, can not guarantee the accuracy of the information read, recommend the use of Huawei certified optical
Troubleshooting Optical Module Issues Symptom An optical port cannot go Up. The optical module cannot be properly identified and optical module information cannot be obtained. After
First, we need to confirm whether the type of optical fiber jumper and optical transceiver is correct, and second, whether the optical fiber jumper is
Learn why an SFP module is not recognized, from compatibility and port issues to fiber mismatch, and follow 6 practical steps to troubleshoot and fix link problems.
This article summarizes several solutions for using optical modules with switches and common problems encountered during usage, along with specific solutions.
The optical module design does not comply with the EMC, its anti-electromagnetic interference capability is low, and the optical module brings electromagnetic interference to surrounding devices.
For details about the optical modules supported by optical ports on switches, see "Appearance and Structure" of a specific switch model in the Hardware Description. The following figure shows the
The optical module installed on the optical interface is not certified for Huawei data center switches. The optical module type does not match the optical fiber type.
Huawei CE and S series switches both incorporate an optical module authentication mechanism. On S series switches, authentication is strict and alarm notifications
Optical transceivers are delicate devices and need to be handled with care. Following the tips above can avoid many common problems and ensure
In summary, make sure that you know what you are doing when plugging in SFP+ modules and fibre optic cables. It may look simple, but transceivers and ports
Module installation is an important factor affecting the service life of switches and modules. In the installation process, be sure to follow the installation steps
Check whether the optical modules are Huawei-certified ones. If not, contact the supplier of the optical modules. If possible, remove and reinstall the optical modules to check whether the fault is rectified.
Context If optical modules that are not certified for Huawei data center switches are used on devices, the devices will generate a large number of alarms to prompt users to replace these
When you are not familiar with optical module products, you may not understand the DDM information of optical module read on the switch. In this
Once the transceiver and fiber optic cable are plugged in properly in the switch optical module, you should be able to view the current information for the optical connection, which helps
Remove and reinstall the optical module. If the fault persists, replace the optical module with a normal one of the same type to check whether the optical module is faulty.
If it is not a Huawei-certified optical module, replace it with a Huawei-certified optical module. If the optical module is installed on a GE port, run the display interfaceGigabitEthernet x/x/x command to
View the Optical Module Status of your Switch Step 1. Log in to the web-based utility of your switch then choose Status and Statistics > Diagnostics
Non-OEM SFP modules may not necessarily adhere to the vendor''s specifications, which could lead to the module not being detected, reduced performance, or the possibility of the
The optical module installed on the optical interface is not certified for Huawei data center switches. The optical module type does not match the optical fiber type.
Possible Causes The optical module model does not match. The transmit or receive optical power of an optical module is not within the normal range. The optical module and optical fiber do not match. The
The following uses the Moduletek SFP-10G-LR module connected to a Huawei S6700 switch as an example to introduce how to read information of the connected optical module on a
For example, the original optical module used for Huawei transmission does not necessarily have no alarm when it is used on Huawei switch. Not all individually packaged optical modules belong to
If this optical module is not delivered from Huawei or is not customized for Huawei, replace it with a Huawei-customized optical module. Cause 2: Temperature of the installed optical
Optical transceivers play a crucial role in modern data communication networks, enabling the transmission and reception of optical signals across fiber
Some non-Huawei-certified switch optical modules are not designed in compliance with EMC standards and have low anti-interference capability. Additionally, they bring electromagnetic
Check whether the optical module is Huawei-certified. If it is not certified by Huawei, replace it with a Huawei certified one. Remove and reinstall the optical module.
Displaying Optical Module Information You can use the display commands to view information about the optical module on an interface, including conventional information, manufacturing information, and
This field indicates whether the rate of the optical module installed on the port matches the port rate. For example, if a non-XGE optical module is installed on an XGE port, the rate of the optical module
Therefore, alarms about optical modules that are not certified for Huawei Ethernet switches are generated. You can run the transceiver non-certified-alarm disable command to disable the alarm
If it does not recognize the SFP Module, verify your module just isn''t inserted upside down. Additionally, check the module slot for any problems and
A switch must use optical or copper modules that have been certified for use on Huawei S switches. Non-certified optical or copper modules cannot ensure transmission reliability and may
