Introduction to 25G and 40G Ethernet Network

When you look at the evolution of networking and the data that drives it, there is no surprise that Ethernet has been and will continue to be the most widely used network interface. Consumers and network designers wish to smoothly migrate to higher network speed—100G/400G without compromising quality. Ethernet speed upgrade path was clearly defined ...

SFP28 and QSFP28 Optical Modules For 25 Gigabit Ethernet

The widely acknowledged Ethernet speed upgrade path was 10G-40G-100G. However, a new development indicates the latest path for server connection will be 10G-25G-100G with potential for future upgrading to 400G. But why 25G? Because moving from 10G to 40G is a big jump and it turns out the incremental cost of 25G silicon over 10G ...
