What Is the Impact of Using Non-Huawei-Certified Optical Modules?
Huawei-certified optical modules have been tested to the highest standards to ensure their quality. Tests include the installation and removal, transmit and receive power, signal transmission quality, basic information query, fault tolerance, compatibility, electro magnetic compatibility (EMC), and environmental performance.
The optical module cannot be installed in an optical interface because of its nonstandard structure.
The structure and size of some non-Huawei-certified optical modules do not comply with the MSA agreement. After such an optical module is installed in an optical interface, the neighbor interface cannot have an optical module installed because the non-Huawei-certified optical module has a nonstandard size.
The device data bus is abnormal because of the data bus defects of the non-Huawei-certified optical module.
Some non-Huawei-certified optical modules have data bus design defects. When such an optical module is used on a device, the data bus of the device will become abnormal. As a result, data on the data bus cannot be read.
Improper edge connector size of the optical module damages the electronic components of optical interfaces.
The edge connectors of some non-Huawei-certified optical modules have a nonstandard size, causing the interface to be short-circuited and damaging the electronic components of optical interfaces.
Optical module temperature monitoring is not standardized, causing alarms to be incorrectly generated.
The temperature monitoring systems of some non-Huawei-certified optical modules do not comply with industry specifications, and so a high temperature is obtained. As a result, the system incorrectly reports a temperature alarm.
The optical module register is set incorrectly. Consequently, parameters and diagnostic information cannot be read or read incorrectly.
The A0 registers of some non-Huawei-certified optical modules are set incorrectly. As a result, parameters and diagnostic information cannot be read or read incorrectly by the data bus.
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.
- 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.
How Can I Determine Whether an Optical Module Is Huawei-Certified?
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 stability.

ENTITYTRAP/3/OPTICALINVALID:OID [oid] Optical Module is invalid.(Index=[INTEGER], EntityPhysicalIndex=[INTEGER], PhysicalName=\" [OCTET]\", EntityTrapFaultID=[INTEGER])
Possible Causes
- The type and wavelength of the local and remote optical modules are inconsistent.
- The optical module is incorrectly installed or the optical fiber is faulty.
- The fiber is too long or the fiber attenuation is too high.
- The remote transmit power is out of the allowed range.
- The optical module is faulty.
Troubleshooting Procedure
You are advised to save the results of each troubleshooting step. This information will help Huawei technical support assist you if the fault persists.
Check whether the local and remote optical modules have the same wavelength.
Run the display transceiver [ interface interface-type interface-number | slot slot-id ] [ verbose ] command to check optical module information on the interface. The Wavelength(nm) field in the command output indicates the wavelength of an optical module. If the two optical modules have different wavelengths, replace one optical module to ensure that the two optical modules have the same wavelength.
If the fault persists, go to step 2.
Check the link connection.
Remove and reinstall the fiber and optical module to ensure they are properly connected. Check whether the fiber connector is dirty or damaged. If so, clean or replace the connector.
If the fault persists, go to step 3.
Check the fiber length.
The fiber length must be shorter than the maximum transmission distance of an optical module. For the maximum transmission distance supported by different optical modules, see Optical Module in the hardware description. If the fiber length exceeds the maximum transmission distance of the optical modules, shorten the fiber length or use optical modules with a longer transmission distance.
If the fault persists, go to step 4.
Check the transmit optical power on the remote device.
Ensure that the transmit optical power on the remote device exceeds the lower threshold.
If the fault persists, go to step 5.
Check whether the fiber type matches the optical module.
Ensure that the fiber type matches the optical module:- A multimode fiber, generally distinguished by an orange outer sheath, is used together with a multimode optical module.
- A single-mode fiber, generally distinguished by a yellow outer sheath, is used with a single-mode optical module.
- Two connected optical modules must have the same wavelength.
Check the optical module type and vendor.
Check whether the local and remote devices use the same type of optical modules from the same vendor. If the connected optical modules have the same wavelength and provide short-distance transmission but alarms indicating low or high optical power occur, the two optical modules may be from different vendors. Although these optical modules have the same wavelength, optical power alarms occur because different vendors design different optical power indicators for these optical modules. To rectify the fault, use optical modules from the same vendor.
If the fault persists, go to step 7.
Replace the parts.
Perform a short fiber loopback test. If the fault cannot be located, replace the optical module or fiber.
If the fault persists, go to step 8.
- Collect the following information and contact Huawei technical support:
- Results of the preceding troubleshooting procedure
- Configuration file, logs, and alarms of the device

How Can I View the Optical Attenuation?
The optical attenuation information cannot be viewed directly. You need to view the current optical power in optical module information to determine whether the optical power is attenuated.
How Can I Determine Whether an Interface Has an Optical Module?
If non-Huawei-certified optical modules are used, the system may be unable to obtain correct information. You are advised to use Huawei-certified optical modules.
Run the display transceiver command to view optical module information.
