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.
