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 ...

25 Gigabit Ethernet: It works already, test event shows

The IEEE P802.3by 25Gb/s Ethernet Task Force advanced its specifications efforts to the Working Ballot stage this past July (see “Ethernet progresses on several fronts at July IEEE 802.3 plenary meeting”). But the technology got a workout the previous month when The Ethernet Alliance held a test event at the University of New Hampshire InterOperability ...

IEEE launches new 25 Gigabit Ethernet, 50-Gbps Ethernet Study Groups

In a demonstration of how quickly it can move in response to market dynamics, the IEEE launched three new study groups at its meeting November 8-13 in Dallas aimed at expanding upon the efforts in process within the IEEE P802.3by 25 Gigabit Ethernet Task Force and leveraging the early work of the IEEE P802.3bs 400 ...

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 ...
