The flattening of the network architecture has greatly promoted the development of 100G high-speed interfaces. Many data centers have also upgraded from 25G networks to 100G. However, when high-speed switches are interconnected with low-speed switches, we will encounter the problem of insufficient SFP28 ports. At this time , We can use ETU CVR-QSFP28-SFP28 converter module to conver...
