Before connecting an optical fiber, attach temporary labels to both ends of the optical fiber for identification. Remove protective caps from optical fiber connectors, insert optical fibers into 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
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
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
Interfaces that use optical modules that are not certified for Huawei data center switches may be unable to go Up. If an optical module that is not certified for Huawei data center switches is used, replace it
The pluggable optical module market was valued at $9.8 billion in 2025 and is projected to reach $26.4 billion by 2034, growing at a CAGR of 11.6%.
The selected optical modules must be supported by the optical interfaces. Check whether the optical module used on the switch is certified by Huawei switches. For the Huawei-certified optical modules,
A switch must use optical or copper modules that have been certified for use on Huawei switches. Non-certified optical or copper modules cannot ensure transmission reliability and may affect service
After the optical module does not satisfy the non-MSA authentication protocol structure dimensions, when inserted into the optical interface of such a light module, since the size of the problem of the
If an optical module is installed in a running switch, you can run the display transceiver command to view parameters of the optical module, including the
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 affect service
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
Context Never look directly into an optical module or the ends of optical fibers. Optical modules and connected fibers emit laser radiation that will cause eye damage. A switch must use optical or copper
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
Install dust plugs on idle optical ports. If an optical module cannot be completely inserted into an optical port, turn the optical module over and try again. Before connecting the optical fiber to the optical
Optical modules are widely used in switches, network interface cards (NICs), routers, and other communication devices. During use, reading optical module information helps understand
Take out the new optical module from the package. Ensure that the optical module is correctly oriented and gently push it into the optical port until you hear a click.
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 mentioned above and pay attention to the
Procedure 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
Troubleshooting for Optical Modules on Huawei Switch Many friends feedback that one problems occurred when using optical modules on switches, now we are
Describes what an optical module is and FAQs, including the fundamentals, appearance and structure, key performance counters, common types, and naming conventions of optical modules, causes of
This article summarizes several solutions for using optical modules with switches and common problems encountered during usage, along with specific solutions.
Context Optical modules and optical fibers are equipped with clips. The optical module or optical fiber is inserted properly when you hear a clack. After making sure that the optical module is inserted
Insert the Gigabit electrical port module into the SFP optical port, and then connect the Category 6 network cable to the Gigabit RJ45 port. This method
NOTICE 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
