Terabit Ethernet

Terabit Ethernet (TbE) is Ethernet with speeds above 100 Gigabit Ethernet. The 400 Gigabit Ethernet (400G, 400GbE) and 200 Gigabit Ethernet (200G, 200GbE)[1] standard developed by the IEEE P802.3bs Task Force using broadly similar technology to 100 Gigabit Ethernet[2][3] was approved on December 6, 2017.[4][5] On February 16, 2024 the 800 Gigabit Ethernet (800G, 800GbE) standard developed by the IEEE P802.3df Task Force was approved.[6]

The Optical Internetworking Forum (OIF) has already announced five new projects at 112 Gbit/s which would also make 4th generation (single-lane) 100 GbE links possible.[7] The IEEE P802.3df Task Force started work in January 2022 to standardize 800 Gbit/s and 1.6 Tbit/s Ethernet. [8] In November 2022 the IEEE 802.3df project objectives were split in two, with 1.6T and 200G/lane work being moved to the new IEEE 802.3dj project. The timeline for the 802.3dj project indicates completion in July 2026. [9]
