How to Identify Huawei-Certified Optical Modules
Method 1: Check for "HUAWEI" on the label
If an optical module has been certified by Huawei, its label contains "HUAWEI", as
shown in
Figure 4-181 "HUAWEI" on the label of a Huawei-certified optical module
Method 2: Run the display esn interface command
If Certified is YES, and VendorName is huawei in the display esn interface
command output, the optical module has been certified by Huawei. Otherwise, it
is not a Huawei-certified optical module.

Improper edge connector size damages electronic devices of optical interfaces.
If a non-Huawei-certified USG optical module with improper edge connector
size is used on an optical interface, electronic devices of the optical interface
will be damaged by short circuits.
Unnormalized temperature monitoring causes incorrect alarms.
The temperature monitoring systems of some non-Huawei-certified USG
optical modules do not comply with industry standards and report
temperature values higher than the real temperature. When such optical
modules are used on a USG, the system will report incorrect temperature
alarms.
Improper register settings cause errors or failures in reading parameters or
diagnostic information.
Some non-Huawei-certified USG optical modules have improper register
values on page A0, which can cause errors or failures when the system
attempts to read parameters or diagnostic information from a data bus.
Some non-Huawei-certified USG optical modules are not designed in
compliance with EMC standards and have low anti-interference capability.
Additionally, they bring electromagnetic interference to nearby devices.
The operating temperature ranges of non-Huawei-certified USG optical
modules cannot meet service requirements. When they are used under
relatively high temperature, the optical power decreases, resulting in service
interruption.
