FiberMall currently offers two types of Copper SFP\u00a0modules, see the table below for\u00a0details:<\/span><\/p>\n

 <\/p>\n

The main difference between the two SFP copper modules is the interface type.<\/span><\/p>\n

 <\/p>\n

As can be seen from the figure above, the external ends of the two copper SFP modules are both standard RJ45 interfaces, while the device end (conductive metal) is distinguished by SerDes and SGMII, which leads to different application situations of the modules.<\/span><\/p>\n
