In 40G short-distance optical network transmission, the conventional optical module solution is to use QSFP-40G-SR4 optical module and 12-core MPO multi-mode OM3 fiber patch cord. Although this solution can realize the upgrade of 10G network to 40G network, it uses MPO branch jumpers to connect 10G equipment and 40G equipment are obviously too expensive, so the industry has given a new optica...

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...
