1、华为定制光模块的标签上都有“HUAWEI”字样的标签,无该标签的为非华为定制光模块。
2、使用display transceiver命令查看光模块信息,如果显示厂商Vendor Name不是“HUAWEI”,那么该光模块不是华为定制光模块。
3、查看是否存在霹葺檠溥非定制光模块告警 用户视图下,执行命令terminal monitor命令开启终端信息显示功能;系统视图下,执行命令undo transceiver phony-alarm-disable打开非定制光模块告警开关。 BASETRAP/1/ENTITYINVALID: OID[ 1.3.6.1.4.1.2011.5.25.129.2.1.9 ] Physicalentity failed.

4、对于某些造假、仿冒的光模块,它们的信息往往是批量复制的,这些光模块的序列号往往都一样。因此,可以使用display transceiver命令观察批量光模块信息,看它们的序列号(Manu. Serial Number)是否一样。如果一样,说明光模块是仿冒的、非华为定制的。但改序列号并非难事,所以这一条也不是非常准确。
5、供货商货源渠道,如果正规渠道会和华为签合作合同,否则可能是工程余料。
