25 Gigabit Ethernet

25 Gigabit Ethernet

An Ethernet standard at 25 gigabits per second (25 GbE). Approved in 2016, 25 GbE was developed by the 25G Ethernet Consortium and IEEE 802.3by task force, which also includes 50 GbE. The 25 and 50 GbE speeds are even divisions of 100 GbE. Therefore, migrating in the future from 25 or 50 to 100 GbE is expected to be considerably more economical than going from 40 to 100 GbE. See 100 Gigabit Ethernet.
