Terabit Ethernet or TbE is Ethernet with speeds above 100 Gbit/s. 400 Gigabit Ethernet (400G, 400GbE) and 200 Gigabit Ethernet (200G, 200GbE) standards developed by the IEEE P802.3bs Task Force using broadly similar technology to 100 Gigabit Ethernet were approved on December 6, 2017. In 2016, several networking equipment suppliers were already offering proprietary solutions for 200G and 400G.
