25 Gigabit Ethernet (25GbE) and 50 Gigabit Ethernet (50GbE) are proposed standards for Ethernet connectivity in a datacenter environment.

The draft uses technology defined for 100 Gigabit Ethernet implemented as four 25-Gbit/s lanes (IEEE 802.3bj).
IEEE 802.3 has formed an 802.3by task force with the objectives to define:
a single-lane 25 Gbit/s 25GBASE-KR PHY for printed circuit backplanes;
a single-lane 25 Gbit/s 25GBASE-CR PHY for 5 m twin-ax cables;
