This article summarizes several solutions for using optical modules with switches and common problems encountered during usage, along with specific solutions.
When using switches, we may encounter many confusions, such as what types of optical modules are needed for different models of Huawei switches, and how to resolve issues encountered
After an SFP-GE copper or optical module is installed on a GE or 10GE optical interface, or a high-speed cable is installed on a 40GE optical interface, the interface works in auto-negotiation
What Is an Optical Module and Its FAQs (V200) Describes what an optical module is and FAQs, including the fundamentals, appearance and structure, key performance counters, common types,
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
An unsupported optical module is installed in the optical interface. For example, an XGE optical module is installed in a GE optical interface; a 100GE optical module is installed in a 40GE
Call Huawei global service hotline or contact software maintenance engineers to verify the software version. If allowed, reboot the device or power off and restart the device. Services on the device are
If not, replace it with a Huawei-certified optical module. If the optical module is installed on a GE port, run the display interface GigabitEthernet x/x/x command to check information about the port, including
Procedure Check whether the optical module has been certified for Huawei Ethernet devices. If not, contact the supplier of the optical module. If possible, remove and reinstall the optical module to
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
Use an optical power meter to test the receive power of the port and check whether the optical fiber is disconnected. Use one optical fiber to form a loop on the port to check whether the port goes Up. If
Some non-certified optical modules are not designed in compliance with EMC standards and have low anti-interference capability. Additionally, they bring electromagnetic interference to nearby devices.
Possible Causes Cause 1: The optical module is not a Huawei-customized optical module. If this optical module was delivered from Huawei early. Cause 2: Temperature 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.
Procedure Use an optical power meter to test whether the transmit power of the optical module is normal. If not, replace the optical module.

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 the fault persists, collect log
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
Huawei 10 Gigabit Single-mode Double-fiber 80km02310SNN Work Package 1 Pack Huawei 02310SNN 10 Gigabit Single Mode Double Fiber 80km Small White Box 1 Pack ZTE SFP 10 Gigabit Single
Check the model and working mode (single-mode or multimode) of the optical modules on the connected devices. Use the patch cords accordingly. If the optical port still fails to go Up, replace the
Check whether the optical module matches the optical fiber. If not, replace the optical fiber or optical module. A single-mode optical module (generally with a center wavelength of 1310 nm or 1550 nm)
exception, SFP is not certified. (EntityPhysicalIndex=67453134, BaseTrapSeverity=5, BaseTrapProbableCause=136192, BaseTrapEventType=9, EntPhysicalContainedIn=67108873
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.
The working temperature range of the optical module does not meet requirements, causing the optical power to be reduced at a high temperature. Subsequently, services are interrupted.
Check whether the transmit optical power and receive optical power of the optical module are within the normal range. If the transmit optical power is beyond the normal range, replace the
If an optical module is not cleaned or protected properly, contaminants may accumulate on the fiber pin in the optical module. As a result, the coupling efficiency is reduced, optical signals are cut off, or
